Curtailing Battery InstabilityPRIORITY
[0001] This application claims priority to U.S. Provisional Patent Application Ser. No. 63 / 618,675 filed on January 08, 2024, which is incorporated herein by reference in its entirety.BACKGROUND
[0002] The present inventions relate to methods, systems, apparatuses, controllers, software, and composition of matter, e.g., materials. The present inventions relate to structures for use in energy manipulation (e.g., energy storage and / or energy release) devices comprising a battery cell (also referred to herein as “cell”), e.g., disposed in a battery. In an example, the present inventions relate to structures such as electrode assemblies for use in energy manipulation devices, such as (e.g., secondary) batteries. The present inventions relate to energy manipulation (e.g., energy storage) devices employing such structures. The present inventions relate to (e.g., methods for) manufacturing such structures and / or energy devices. In an example, the present invention relates to methods and structures such as electrode assemblies for use in energy manipulation (e.g., energy storage) devices such as secondary batteries, to energy manipulation (e.g., energy storage) devices employing such structures, and to methods for manufacturing such structures and energy devices.
[0003] In some cases, there may be shortcoming(s) related to such batteries, their use, their storage, their maintenance, and / or their manufacture, e.g., the process of making such batteries. In an example, there are a number of shortcomings related to batteries and the process of making them. A problem occurring in the energy manipulation (e.g., energy storage) device (e.g., battery) is its heating, e.g., due to battery abuse. The battery abuse may comprise thermal, electrical, or mechanical abuse resulting in the temperature increase. The temperature increase may occur at least in part due to increased electrical current between two opposing electrodes of a cell, e.g., at least in part due to a short. In normal operation of a cell, current passes from one electrode to its opposing electrode, mainly through a separation space between then, the separation space contacting the two opposing faces of the batteries. There may be a residual current passing through a volume contacting one or more sides of the two opposing electrodes. The increased heat may be at least in part due to Joule heating. Such heating may cause adverse effects to the energy manipulation (e.g., energy storage) device and / or its surroundings. The adverse effect may be at least in part due to instability of a cell of the battery and / or of the battery. Such heating may be caused by increased current between the opposing electrodes. Such heating may be generated during a thermal runaway reaction, e.g., an uncontrollable chain reaction. Suchheating may be generated in the battery at a rate exceeding the battery heat dissipation rate. The fast-increasing heat may cause a chemical (e.g., exothermic) reaction, generating additional heat. Such heat may cause adverse effects comprising release of toxic gas, fire, or explosion. The adverse effect(s) may be adverse to the cell, to the battery, and / or objects disposed in the environment outside of the cell, whether animate or inanimate. Outside of the cell can comprise outside of the battery housing, e.g., in an ambient environment. The adverse effects may be defined according to jurisdictional definition in the jurisdiction in which the battery is manufactured, stored, used, and / or otherwise located in. It may be advantageous to curtail (e.g., prevent) the occurrence of such adverse effect(s).SUMMARY
[0004] In some aspects, the present disclosure resolves one or more of the aforementioned hardships. In some embodiments, the present disclosure provides solutions to curtail the adverse effects. In some embodiments, the present inventions relate to method(s) (e.g., technique), device(s), apparatus(es), system(s), and design(s), which build a battery comprising cell(s). The battery may be configured to curtail the adverse effects, e.g., at least in part by shutting of the residual current and / or the load current which is in normal operation the main current of the battery. In an example, the cell may contact a dynamic insulator having a susceptibility to a triggering event such as reaching a temperature threshold. The triggering event may trigger material change(s) in the dynamic insulator that curtail(s) the rise in temperature of the cell (and / or of the battery), the rate of charge carrier flowing through the dynamic insulator, the concentration of the charge carriers in the dynamic insulator, or any combination thereof. In an example, at least one material type of the dynamic insulator may be susceptible to a triggering event. The triggering event may cause a substantial (e.g., material) change in (i) the flow rate and / or (i) the concentration of, the charge carriers in the dynamic insulator. The susceptibility of the at least one material type may depend at least in part on (a) a temperature threshold, (b) a concentration threshold of the charge carriers, or (c) a flow rate of the charge carriers. In an example, the cell may contact a dynamic insulator having at least one temperature susceptible material that curtails (e.g., prevents) flow of the residual current based at least in part of the temperature of the dynamic insulator. Such (e.g., temperature related) event triggering property / properties of the dynamic insulator may induce a substantial reduction and / or shutdown in the residual current pathway otherwise passing through the dynamic insulator and between the opposing electrodes of a cell. Such curtailing of residual current may (a) reduce the overall (e.g., Joule and / or other) heating of the cell during the adverse effect, and / or (b) reduce the extent of the runaway reaction, e.g., during an external short circuit. Such curtailing of the residual current flow may improve the overall safety of the battery.

[0048] While various embodiments of the inventions have been shown, and described herein, it will be obvious to those skilled in the art that such embodiments are provided by way of example only. Numerous variations, changes, and substitutions may occur to those skilled in the art without departing from the invention. It should be understood that various alternatives to the embodiments of the invention described herein might be employed. The various embodiments disclosed herein are combinable, as appropriate.
[0049] Reference throughout the specification to “various embodiments,” “some embodiments,” “one embodiment,” “some example embodiments,” “one example embodiment,” or “an embodiment” means that a particular feature, structure, or characteristic described in connection with any embodiment is included in at least one embodiment. Thus, appearances of the phrases “in various embodiments,” “in some embodiments,” “in one embodiment,” “some example embodiments,” “one example embodiment,” or “in an embodiment” in places throughout the specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures or characteristics may be combined in any suitable manner in one or more embodiments.
[0050] Terms such as “a,” “an” and “the” are not intended to refer to only a singular entity but include the general class of which a specific example may be used for illustration. The terminology herein is used to describe specific embodiments in the present disclosure, but their usage does not delimit to the specific embodiments of the present disclosure. The term“includes” means includes but not limited to, the term “including” means including but not limited to, and the term “based on” means based at least in part on.
[0051] When ranges are mentioned, the ranges are meant to be inclusive, unless otherwise specified. For example, a range between value 1 and value 2 is meant to be inclusive and include value 1 and value 2. The inclusive range will span any value from about value 1 to about value 2. The term “adjacent” or “adjacent to,” as used herein, includes “next to,” “adjoining,” “in contact with,” and “in proximity to.” When ranges are mentioned (e.g., between, at least, at most, and the like) the endpoint(s) of the range is / are also claimed. For example, when the range is from X to Y, the values of X and Y are also claimed. For example, when the range is at most Z, the value of Z is also claimed. For example, when the range is at least W, the value of W is also claimed.
[0052] The conjunction “and / or” as used herein in “X and / or Y” - including in the specification and claims - is meant to include the options (i) X, (ii) Y, and (iii) X and Y, as applicable. The phrase “including X, and / or Y” is meant to have the same meaning as the phrase “comprising X or Y.”
[0053] When ranges are specified for an attribute, it is meant herein that the attribute may include the value specified at the end of the range. For example, when the attribute is of a value of at least about X, the attribute can be X, or any value greater than X. For example, when the attribute is of a value of at most about Y, the attribute can be Y, or any value smaller than Y. For example, when the attribute is of a value from V to Z, the attribute can be V, the attribute can be Z, or the attribute can be any value between V and Z.
[0054] The term “operatively coupled,” “operatively configured,” or “operatively connected” refers to a first mechanism that is coupled (or connected) to a second mechanism to allow the intended operation of the second and / or first mechanism. The coupling may comprise physical or non-physical coupling. The non-physical coupling may comprise signal-induced coupling (e.g., wireless coupling).
[0055] The phrase “is / are structured” or “is / are configured,” when modifying an article, refers to a structure of the article that can bring about the referred result.
[0056] Fundamental length scale (abbreviated herein as “FLS”) comprises any suitable scale (e.g., dimension) of an object. For example, an FLS of an object may comprise a length, a width, a height, a diameter, a spherical equivalent diameter, a diameter of a bounding circle, a diameter equivalent of a bounding sphere, a radius, a spherical equivalent radius, or a radius of a bounding circle, or a radius of a bounding sphere.
[0057] A central tendency as understood herein comprises mean, median, or mode. The mean may comprise a geometric mean.
[0058] Performing a reversible first operation is understood herein to mean performing the first operation and being capable of performing the opposite operation to that first operation(e.g., which is a second operation). For example, when a controller directs reversibly opening a shutter, that shutter can also close, and the controller can optionally direct a closure of that shutter. For example, when an attractor reversibly binds to a charge carrier, that attractor can also release that charge carrier after its binding.
[0059] As noted herein, implementations of the present disclosure relate to (e.g., secondary) batteries, the structures that make up the (e.g., secondary) batteries, and the methods and processes for manufacturing the structures and batteries. As used herein, the term “anode” used in the context of a secondary battery may refer to the negative electrode in a (e.g., secondary) battery. “Anode material” or “anodically active” as used herein, may refer to a material or materials suitable for use as the negative electrode of a (e.g., secondary) battery. The term “cathode” as used herein in the context of a (e.g., secondary) battery may refer to the positive electrode in a secondary battery. “Cathode material” or “cathodically active” as used herein, may refer to a material or materials suitable for use as the positive electrode of a (e.g., secondary) battery.
[0060] In some implementations described herein, the term “electrode” may be used to refer to either the anode or the cathode, and the term “counter-electrode” may refer to the other or opposite electrode. For the sake of explanation (e.g., for didactive purposes), implementations may be described in terms of “electrode” and “counter-electrode.” It should be appreciated that in these implementations, the term electrode may be replaced by the term anode while the term counter-electrode may be replaced by the term cathode. Alternatively, in these implementations, the term electrode may be replaced by the term cathode while the term counter-electrode may be replaced by the term anode.
[0061] Curtailing may comprise deterring, slowing, hindering, slowing, limiting, halting, shutting off, ceasing, or stopping. Curtail may comprise deter, slow, hinder, slow, limit, halt, shut off, cease, or stop.
[0062] In some embodiments, the battery is configured to curtail (e.g., reduce, or prevent) the occurrence of battery heat-up and / or runaway reaction, e.g., due to residual current. At times, when a residual current in the cell exceeds an activation energy barrier, a thermal runaway (e.g., exothermic) reaction starts resulting in (additional) heating of the battery, e.g., that may be uncontrollable. Such uncontrollable heating and / or reaction may cause adverse effect(s) such as disclosed herein. The adverse effects may comprise substantial harm, e.g., damage. The adverse effect may be irreversible, uncontrollable, cause the cell to operate outside of its prescribed specifications, and / or cause the battery to operate outside of its prescribed specification. The specification may be prescribed by the battery manufacturer and / or the client. In an example, the substantial damage is to the battery, to an inanimate object in an ambient environment external to the battery, to personnel in the ambient environment external to the battery, or any combination thereof. The substantial damagemay be caused at least in part by the cell catching fire and / or exploding. It may therefore be beneficial to curtail (e.g., prevent) such substantial temperature rise and / or runaway reaction within the battery. The battery may be a primary or a secondary battery. The battery may or may not be rechargeable. The battery may or may not be a single use battery. The battery may comprise a primary battery cell, or a secondary battery cell. The battery may be a primary battery or a secondary battery. The battery may assume a configuration of a cylinder or a prism. The battery may comprise one or more battery cells. The battery cell may be folded, assume a (e.g., substantially) planar configuration, or be folder, e.g., in a fold comprising a spiral, sinusoidal, zigzag, or top-hat, fold. A set of battery cells may be disposed one on top of each other.
[0063] Fig. 1 shows in example 100 a schematic graph depicting battery current (I) over time (t), and temperature (T) of the battery over the time (t), in which are subject to an External Short Circuit (ESC) test, e.g., not during normal operation of the batteries. Section 111 during time window t1 depicts an initial heating of the battery, the heating hardly affects the current 101, above a threshold temperature, the current greatly diminishes, which is depicted during time window t2. The fast-diminishing current may be attributed to effective elimination of the load current, e.g., due to shutoff of the separator. Section 102 of the current graph, depicts the steep reduction of the current in the battery during temperature approaching threshold 112, occurring during time window t2. While the main current may be greatly diminished, a residual current 104 can remain in the battery. The residual current can contribute to continuous increase of the battery temperature above threshold temperature 112. Such an increase in temperature may initiate a runaway reaction contributing to uncontrollable temperature increase as depicted in 113 occurring in time window t3. When the residual current also diminishes, e.g., as is depicted in 105, the temperature of the battery may remain (e.g., substantial) constant, e.g., as is depicted in 114, or may reduce, as is depicted in 115. Reduction of the temperature may occur when the current (e.g., 105) is sufficiently curtailed, e.g., diminishes effectively to zero, or to a measurably zero current.
[0064] Fig. 1 shows in example 100 a schematic vertical cross section in a battery, showing arrangement and / or folding of battery cells with respect to a Cartesian coordinate system. In example 151, battery cells are arranged parallel to each other. Examples 152-155 show various folding of a sheet comprising one or more battery cells, with 152 showing a zigzag fold, 153 showing a top hat fold, 154 showing a sinusoidal fold, and 155 showing a spiral (e.g., rolling) fold. The battery may comprise a battery cell folded in a wound (e.g., jelly roll) configuration having an oblong or cylindrical configuration, e.g., as shown in Fig. 13, 1350.
[0065] In some embodiments, a battery comprises at least one cell. A cell may comprise two opposing electrodes (an anode and a cathode) separated from each other by a separation space. The separation space may comprise an electrolyte or a separator. The separationspace may comprise more than one separator. In an example, the separation space comprises the electrolyte and the separator, e.g., comping a polymer or a resin. Under normal conditions, the separator can be configured (a) to hinder (e.g., prevent) contact between the two opposing electrodes of the cell, and (b) to allow charge carriers to pass through the separator when propagating (e.g., progressing, or traveling) from one electrode to its opposing electrode. The normal conditions may comprise normal operation, (e.g., physical storage such as in a warehouse) storage, maintenance, or shipping conditions, e.g., ambient conditions. Under the normal conditions, the charge carriers may pass from one opposing electrode to another at least in part by using the electrolyte. The electrolyte may comprise of one or more distinct chemical types. The charge carrier may comprise a positively charged ion (cation), e.g., a metal cation of an alkali metal or an alkali earth metal. In an example, the charged ion is lithium. Lithium based batteries (e.g., Lithium-based secondary batteries) are a type of energy manipulation (e.g., energy storage) device having one or more cells. In some embodiments, a cell comprises carrier ions that propagate between the opposing electrodes during use, at least in part by using electrolyte, e.g., propagate between a cathode structure and an anode structure at least in part by using the electrolyte. In an example, lithium-based secondary batteries are a type of energy manipulation (e.g., energy storage) device having cells in which carrier ions, such as lithium, sodium, potassium, calcium or magnesium ions, travel between a cathode structure and an anode structure through an electrolyte within each cell. The carrier ions may comprise lithium, sodium, potassium, calcium, or magnesium ions. The opposing electrodes (e.g., the anode structure and cathode structure) are separated by the separator structure (also referred to herein as the “separator”) disposed in the separation space. The separation between the opposing electrodes may occur during the normal conditions. The normal conditions may comprise during use, e.g., at a time comprising (a) during assembly of the battery, or (b) during battery operation. Current collectors (e.g., wires) can pull electric current from the respective current carrying electrode and enable transfer of the current from the cell to the external environment, e.g., to the ambient environment external to the battery housing. An electrode may be operatively coupled with one or more current collector(s). In an example, an electrode is operatively coupled (e.g., connected) to at least one current collector such as wire. In an example, current from the respective active electrochemical electrodes and enable transfer of the current to the environment outside the battery. In an example, each of the anode and cathode current collectors pull electric current from the respective active electrochemical electrodes and enable transfer of the current to the environment outside the battery, e.g., and outside of the battery housing. In an example, an anode current collector is configured to pull electric current from an anode, e.g., to transfer the current to the environment outside the cell and / or the battery such as outside of thebattery housing. In an example, a cathode current collector is configured to pull electric current from a cathode, e.g., to transfer the current to the environment outside the cell and / or the battery such as outside of the battery housing. The battery may comprise one or more cells. The battery may comprise a housing. The current collector may carry the current outside of the cell and into the battery housing, outside of the battery housing, or a combination thereof. The current collectors of the anodes in a set of cells may be coupled (e.g., in parallel) to a main anode current collector. The current collectors of the cathode in a set of cells may be coupled (e.g., in parallel) to a main cathode current collector. The main cathode current collector may be disposed on the same face of the set of cells as the main anode current collector. The main cathode current collector may be disposed on a different face (e.g., at an opposing face) of the set of cells as the main anode current collector. The external battery contacts on a face parallel to, or normal to, to the long axis of the electrode of the cell.
[0066] In some embodiments, a battery cell comprises a pair of opposing electrodes and a separation space disposed between the opposing electrodes of the pair. In some embodiments, the electrode assumes the shape of a sheet. The sheet may be planar. The sheet may be substantially two dimensional. The thickness of the sheet may be substantially smaller than the length of the sheet, and substantially smaller than the width of the sheet. The separation space may comprise a separator, e.g., having a shape of a sheet. The electrode and / or separator, may be elongated. A subject face may be of a cell or of a component of the cell, the subject face having the largest surface area of the component’s faces, e.g., face types. The component of the cell may comprise a reference electrode, its counter electrode, or the separator. The subject face may be of the battery cell. The ratio of a subject face of the component, the subject face having the largest surface area of the faces of the component, may be at least about 1:2, 1:5, 1 :10, 1:50, 1:100, or 1:500 width per length. The face may be of the electrode of the cell (e.g., anode), or of the separator of the cell. The cell may be configured for deposition in a prismatic (e.g., cuboid) housing. The subject face may assume a shape configured to fit in a cross section of a face of the prism different than the face having the largest cross-sectional area. The subject face may assume a shape configured to fit in a cross section of the face of the prism having the smallest cross- sectional area. The face of the prism having the smallest cross-sectional area, can fit at most an integer number of the subject face, the integer number being at most about 5, 4, 3, 2, or 1. In an example, the face of the prism having the smallest cross-sectional area, can fit at most one subject face. The subject face may assume a shape configured to fit in a cross section of a face of the prism having the medium sized cross-sectional area. The face of the prism having the medium cross-sectional area, can fit at most an integer number of the subject face, the integer number being at most about 5, 4, 3, 2, or 1. In an example, the faceof the prism having the medium cross-sectional area, can fit at most one subject face. The face of the prism having the largest cross-sectional area, can fit at most an integer number of the subject face, the integer number being at most about 5, 4, 3, 2, or 1. In an example, the face of the prism having the largest cross-sectional area, can fit at most one subject face. The largest cross-sectional area of the subject face may be elongated, e.g., rectangular.
[0067] In some embodiments, the cell comprises a separator. The separator may be configured (a) to curtail (e.g., hinder or prevent) the cathode from contacting the anode, and (b) to allow ions to pass through the separator from one electrode to its opposing electrode, the ions passing at least in part by using electrolyte disposed at least between the opposing electrodes in the separation space. In an example, the separator is disposed between the opposing electrodes in a battery cell (also referred to therein as the “cell”). The separator may extend outside the surface of the opposing electrodes, which surfaces face each other. The electrolyte may be disposed (e.g., situated, or located) withing the battery housing. The electrolyte may be disposed in the cell. The electrolyte may be disposed within the immediate location of the cell. The electrolyte may comprise a polymer, a mixture of polymers. The polymer may be a copolymer. The electrolyte may contact the cell (e.g., also) outside of the separation space. The electrolyte may be disposed in a volume contacting the cell. In an example, the electrolyte is disposed in the battery housing, e.g., in a volume isolated (e.g., separated) from the ambient environment external to the battery housing. The isolated surrounding may comprise one or more cells.
[0068] In some embodiments, the separator is configured to (i) be electrically insulating and (ii) allow for ionic conduction of the charge carriers. In an example, the ionic conduction may initiate once the electrolyte fills the pore space. The separator may be configured to allow the charge carriers, such as lithium ions, to pass through from one face of the separator to its opposing face. The ionic conduction may be facilitated (e.g., done) at least in part by the charge carriers. The ionic conduction may be facilitated (e.g., done) at least in part by the electrolyte. The ionic conduction may take place during conditions of the cell comprising during use or during its storage. The ionic conduction may effectuate (e.g., be done) during operation and / or during an electrode buffering process of the cell, e.g., during pre-charging of the anode with the charge carriers. The charge carriers may be of one or more chemical types. In an example, the ionic conduction is done during operation and / or during a pre- lithiation (or buffer) process of the cell, e.g., pre-lithiation of the anode.
[0069] In some embodiments, a battery cell comprises an electrode (e.g., reference electrode), a counter electrode, and a separation space. The separation space may comprise a separator, e.g., having a material comprising conduits or pores, e.g., micro conduits, or micropores. The pores and / or conduits may be configured to facilitate ions topropagate through the pores. The conduits may be channels. Pores of the separator may be coupled with form the conduit. The battery cell may comprise, or may be coupled with, an insulator such as a dynamic insulator. The battery cell may comprise, or may be coupled with, a dividing space. At least one component may be electrically insulating, e.g., the separator body, the insulator, or at least one component of the dividing space. The dividing space and the separating space may or may not have the same material content.
[0070] Fig. 2 shows in example 200 a schematic representation of a battery cell, the battery cell comprising an electrode 202a - C (e.g., a cathode), and an opposing electrode 205a - A (e.g., an anode). A separator is disposed in separator space 203 - B. The battery cell is disposed in a battery having housing 209. The battery can optionally have an insulator 204 that may or may not be the dynamic insulator. Under normal conditions during use of the battery, the main current is a load current 206 passing from one electrode to its opposing electrode, and through separation space 203. There may be a residual current 201 passing outside of separation space B, and through volume 204, e.g., through the dynamic insulator. When temperature rises, the separator in separation space 203 may shut down, greatly diminishing (e.g., eliminating) the flow of the load current 206. A triggering event of current shut down through a volume may comprise temperature above a threshold, flow of charge carriers above a threshold, concentration of the charge carriers above a threshold. When the insulator in space 204 is unsusceptible to a triggering event, the residual current will continue to flow between the opposing electrodes, even though components of the separation space (e.g., 203) will be susceptible to the triggering event, e.g., and consequently the load current will (e.g., effectively) shut down. When the insulator in space 204 has a susceptibility to a triggering event that is different from (e.g., lower than) that of components of the separation space (e.g., to the separator), the residual current may continue to flow between the opposing electrodes, even though the load current is (e.g., effectively) shut down. In these cases, a shut down on the separator in separation space 203 will not affect the flow of residual current 201. If volume 204 comprises an insulator, the insulator contacts at least at opposing sides 202b and 202c of electrode 202a and at opposing sides 205b and 205c of counter-electrode 205a.
[0071] Fig. 2 shows in example 210 a schematic representation of a battery cell, the battery cell comprising an electrode 212 - C (e.g., a cathode), and an opposing electrode 215 - A (e.g., an anode). A separator is disposed in separator space 213 - B. The battery cell is disposed in a battery having housing 219. The separation space extends 221 beyond electrode 212, and extends 222 beyond counter electrode 215, the extension being along a long axis of each of the electrode, the long axis depicted in Fig. 2. The battery has a dynamic insulator 204 that was triggered due to a triggering event experienced in the dynamic insulator. The triggering event may comprise temperature above a threshold, flow ofcharge carriers above a threshold, concentration of the charge carriers above a threshold. Under the event triggering conditions, the load current 216 may or may not be passing through separation space 203. In an example, during the triggering conditions the load current is (e.g., substantially, and / or effectively) shut down. The triggering event may cause the dynamic insulator to curtail (e.g., effectively stop) the residual current. In the example shown in 210, residual current 211 does not pass through space 214 and outside of separation space B, volume 214 comprises (e.g., is filled by) the dynamic insulator. A change between the interiors 204 and 214 can depict a change in the dynamic insulator due to the triggering event. The triggering event(s) of the materials in the separation space (B) (e.g., of the separator) may or may not be (e.g., substantially) the same as the triggering event(s) of the dynamic insulator (e.g., of the insulating material). The dynamic separator may be configured to shut down the residual current before, after, or during the time at which the load current is shut down, e.g., due to a change in the separator and / or in the electrolyte in the separation space.
[0072] In some embodiments, one or more cells are disposed within a housing to form the battery. The housing may insulate the battery from one or more reactive agents in the ambient environment external to the battery. The reactive agent(s) may comprise oxygen, water, alcohol, thiol, sulfuric acid, phosphoric acid, carboxylic acid, or hydrogen sulfide. The reactive agent(s) may be oxygen based, sulfur based, and / or phosphorous based. The reactive agent(s) may comprise water or oxygen. In an example, the reactive agent(s) comprise water in a liquid and / or vapor form. The water may be in a droplet form. The housing may be configured to insulate the cell(s) from the reactive agent(s) present in the ambient environment external to the battery, e.g., to curtail (e.g., hinder, or prevent) reactive agent(s) from reaching the cell such as including reaching the electrode(s).
[0073] Figure 3 shows schematic perspective view examples of batteries and battery cell architecture therein relative to a Cartesian coordinate system. Example 300 shows a cylindrical battery housing having a length 302 and height 301, which is a diameter. The battery may comprise cell(s) that form a rolled sheet. In example 300, each of the bottom and top faces of the cylinder has a smaller surface area as compared to the side surface of the cylinder - to the curved surface of the cylinder. Example 330 shows a prismatic battery housing that is a rectangular prism, or a cuboid. The battery has length 332, height 331 , and width 333. Battery cells 335 are stacked in the battery along height 331 , and along the Z direction. In example 330, face XY has a larger surface area than face XZ, and face XY has a larger surface area than face YZ. Example 350 shows a prismatic battery housing that is a rectangular prism, or a cuboid. The battery has length 352, height 351, and width 353. Battery cells 355 are stacked in the battery along length 352, and along the X direction. Inexample 350, face XY has a larger surface area than face XZ, and face XY has a larger surface area than face YZ.
[0074] In some embodiments, the cell is arranged (e.g., substantially) perpendicular to the face of a prismatic (e.g., cuboid) battery having the largest surface area. At times, the largest surface area face of the anode, the separation space, the separator, the cathode, and / or the dividing space, is disposed (e.g., substantially) normal to the face of the battery having the largest surface area. Fig. 3, 350 shows an example of battery cells such as cells 335, disposed normal to the XY face of the battery, which XY face has the largest surface area among the battery’s faces. The surface area of the cell, in example 350, is at most the surface area of YZ face of the battery, or smaller. Cells arranged normal to the largest surface area face of the battery in which they are disposed (e.g., Fig. 3, 350), have a larger combined cell side (e.g., edge) surface area, as compared to (a) cells arranged parallel to the largest surface area face of the battery in which they are disposed (e.g., Fig. 3, 330) and / or to (b) cylindrical battery such as a wound cell (e.g., jelly roll) battery (e.g., Fig. 3, 300). In some embodiments, the greater the combined side (e.g., edge) surface area of the cells, the greater the residual current role is in the total current of the battery. When the cell comprises at least one uneven side, e.g., as is depicted in Fig. 2, 220, the uneven (e.g., misaligned) side creates a wavy side of a set of cells. The wavy side may or may not contribute to the amount of residual current passing between an anode and a cathode of a cell, e.g., through the insulator.
[0075] In some embodiments, the battery comprises battery cells. The battery cells may be stacked along an axis. A dividing space may be disposed between every two immediately adjacent cells such that a first cell contacts the first face of the dividing space, and a second cell contacts a second face of the dividing space opposing its first space. The dividing space may comprise an insulator, e.g., any insulator disclosed herein. The insulator may or may not comprise the dynamic insulator. The dividing space may be configured to electrically separate one cell from another. The battery stacks may follow a pattern, the pattern may comprise a sequence. The sequence may comprise an arrangement of components of the battery cell with respect to each other. The sequence may comprise an anode, a separation space, a cathode, and a dividing space. The sequence may follow a CBAS pattern, or a CBASABCS pattern, with C designating a cathode, B designating a separation space, A designating an anode, and S designating the dividing space, e.g., see Fig. 4. The battery cells may be stacked in one or more groups. The separation space may comprise two opposing faces. A face of the separation space contacting the anode, and an opposing face contacting the cathode. The cell may comprise components comprising an anode, a cathode, a separation space, and an optional dividing space. The components of the cell may be disposed along an axis. The components of the cell may be (e.g., substantially)symmetrically arranged along the axis, e.g., in mirror symmetry, the mirror plane running along the axis, and / or in a rotational symmetry, the rotational axis running along the cell stacking axis (e.g., parallel to axis 490 in Fig. 4). At least two components of the cell may extend in a direction (e.g., substantially) perpendicular to the cell stacking axis at a (e.g., substantially) same distance. At least two components of the cell may extend in a direction (e.g., substantially) perpendicular to the cell stacking axis at a different distance. The different distance extension of the components forms a corrugated (e.g., misaligned) face of the cell, and of the set of cells, e.g., as depicted in Fig. 2, 220. See also sides (e.g., edges) of cell sets in Fig. 4, 400, and 450. In an example, the cathode extends less than the anode, the extension being in a direction perpendicular to the cell stacking axis. In an example, the separation space extends more than the anode and / or more than the cathode, the extension being in a direction perpendicular to the cell stacking axis.
[0076] Fig. 4 shows a schematic cross-sectional example 400 of a battery comprising cathode 402, anode 405, separation space 406, and dividing space 407. The battery cells are disposed in volume 404 of the battery that can include an insulator such as a dynamic insulator. The battery cells are stacked along an axis 490, in a repeating CBAS arrangement. Each anode A in the battery is operatively coupled (e.g., connected) with a current collector such as 413, the anode current collectors being coupled in parallel to a main anode current collector 414, ending with cathode contact 411. Each cathode C in the battery is operatively coupled (e.g., connected) with a current collector such as 416, the anode current collectors being coupled in parallel to a main cathode current collector 417, ending with anode contact 412.
[0077] Fig. 4 shows a schematic cross-sectional example 450 of a battery comprising cathode 452, anode 455, separation space 456, and dividing space 457. The battery cells are disposed in volume 454 of the battery that can include an insulator such as a dynamic insulator. The battery cells are stacked along an axis 490, in a repeating CBASABCS arrangement. Each anode A in the battery is operatively coupled (e.g., connected) with a current collector such as 463, the anode current collectors being coupled in parallel to a main anode current collector 464, ending with cathode contact 461. Each cathode C in the battery is operatively coupled (e.g., connected) with a current collector such as 466, the anode current collectors being coupled in parallel to a main cathode current collector 467, ending with anode contact 462. In Fig. 4, the main cathode current collector is disposed on a different face of the set of cells as the main anode current collector, which is the opposing face.
[0078] Fig. 5 shows an example of a battery portion having stacked cells comprising dividing space 501 (S), anode 502 (A), separator space 503 (e.g., comprising a separator) (B), and cathode 504 (C), the cell repeating in a SABC sequence. In the example shown in Fig. 5,dividing space 501 is (e.g., substantially) identical to separator space 503, e.g., in terms of its material content and / or general physical dimensions. The wavy (e.g., misaligned) formation of the sides (e.g., edges) of the cells in the set of cells shows at the exposed portion of the stacked battery cells in the sequence of cells, e.g., the cell comprising components 502-504. The content of the separator space can be (e.g., substantially the same) as the dividing space.
[0079] In some embodiments, the battery comprises an insulator. The insulator may comprise a ceramic material. The ceramic may comprise alumina (AI2O3), zirconia (ZnCh), magnesium oxide (MgO), boron nitride (BN), mullite, boehmite, or silicon carbide (SiC, e.g., in pure form). The insulator may comprise an allotrope of elemental carbon that is non- conductive. The non-conductive allotrope of elemental carbon may comprise amorphous carbon, carbon foam (e.g., nanofoam), or Z-ACA allotrope. In an example, some (e.g., secondary) batteries rely on a paste of aluminum oxide (alumina) to create a porous layer on both XY faces of a cell. The ceramic may be utilized with or without an additive, e.g., the additive comprises a polymer or a resin. The ceramic may be deposited during the battery generation process, e.g., as a slurry that includes a solvent such as a hydrophobic solvent, e.g., Naphtha. The hydrophobic solvent may comprise aromatic or aliphatic compound. The hydrophobic solvent may be branched. The slurry may comprise a solvent, a binder (e.g., polymer), and a ceramic (e.g., alumina). The binder can comprise an anhydride, or an alkene. The polymer may be a copolymer. The solvent can comprise an aromatic hydrocarbon. The viscosity of the slurry utilized for deposition of the insulator can be at least about 1500 centipoise (cP), 1700 cP, 1750 cP, 2000 cP, 2570 cP, or 3000 cP, e.g., at ambient temperature or at 37°C. The viscosity of the slurry utilized for deposition of the insulator can be at most about 1700 cP, 1750 cP, 2000 cP, 2570 cP, 3000 cP, or 4000 cP. The viscosity of the slurry utilized for deposition of the insulator can be at of any viscosity values between the aforementioned viscosity values, e.g., from about to about, or from about to about. The viscosity can be measured at ambient temperature, e.g., at 20°C, 25°C, 30°C or 35°C. During manufacturing (e.g., during deposition), the dynamic insulator (e.g., slurry thereof) may assume the same viscosity properties as the non-dynamic (e.g., ceramic) insulator (e.g., slurry thereof). In an example, when there is an external short circuit (ESC) that causes the loading current to effectively cease, (e.g., ionic) current can continue to pass from the anode to the cathode through the insulator (e.g., through the aluminum oxide layer), even after the separator has reached its shutdown temperature. The insulator can exclude a dynamic component susceptible to the triggering event such as the shutdown temperature of the separator. A non-dynamic insulator can exclude a dynamic component susceptible to the triggering event in an amount in which the dynamic component will (e.g., substantially and / or measurably) curtail the flow of residual current and / or ions though the insulator volume. In anexample, the non-dynamic insulator excludes a dynamic component susceptible to the triggering event in an amount in which the dynamic component will (e.g., substantially and / or measurably) stop the flow of residual current and / or flow of ions though the insulator volume. When there is an external short circuit (ESC) event, ionic current can continue to pass from one electrode to its opposing electrode (e.g., from the anode to the cathode) through the electrolyte of the insulator (e.g., comprising an aluminum oxide layer) electrolyte, e.g., after the separator has reached its shutdown temperature. In an example, the insulator (this porous layer) must be electrically insulating to avoid shorts and (e.g., but) also allow for ionic conduction once the electrolyte fills the pore space - to allow lithium ions to pass through during the pre-lithiation (or buffer) process. In an example, a dynamic insulator susceptible to the triggering even(s) can also help prevent shorting between the cathode and anode.
[0080] In some embodiments, the battery and / or cell comprises a polymer. The polymer may comprise a copolymer, or a polymer mixture. The polymer may be included in the insulator, in the electrode, in the separator space, in the dividing space, or any combination thereof. The battery and / or the battery cell, may comprise at least one type of the polymer. At least two components of the cell and / or battery, may comprise the same polymer type. At least two components of the cell and / or battery may comprise different polymer types. In an example, the polymer is hydrophobic. In an example, the polymer is non-aqueous and / or non-polar.
[0081] In some embodiments, the battery and / or cell comprises a resin. The resin may comprise a resin mixture. The resin may be included in the insulator, in the electrode, in the separator space, in the dividing space, or any combination thereof. The battery and / or the battery cell, may comprise at least one type of the resin. At least two components of the cell and / or battery, may comprise the same resin type. At least two components of the cell and / or battery may comprise different resin types. In an example, the resin is hydrophobic. In an example, the resin is non-aqueous and / or non-polar.
[0082] In some embodiments, the battery and / or cell comprises an electrolyte. The electrolyte may comprise an electrolyte mixture. The electrolyte may be included in the insulator, in the electrode, in the separator space, in the dividing space, or any combination thereof. The battery and / or the battery cell, may comprise at least one type of the electrolyte. At least two components of the cell and / or battery, may comprise the same electrolyte type. At least two components of the cell and / or battery may comprise different electrolyte types. The electrolyte may be configured to be compatible with utilization of the battery at least under the normal conditions. In an example, the electrolyte is hydrophobic. In an example, the electrolyte is non aqueous and / or non-polar.
[0083] In some embodiments, the insulator is a dynamic insulator. The dynamic insulator may comprise a polymer, a resin, or an electrolyte. The dynamic insulator may or may not(e.g., also) comprise the ceramic. In an example, the dynamic insulator comprises a porous layer. In an example, the cell and / or battery includes the dynamic insulator. The dynamic insulator (porous layer) may help in curtailing (e.g., hindering or preventing) current shorting event(s) occurring between the opposing electrodes (cathode and anode) of the cell.
[0084] In some embodiments, the battery comprises (e.g. and rely on) the dynamic insulator (also referred to herein as an “insulating layer”) in which one or more insulating material types are disposed in a volume. The dynamic insulator may contact one or more faces of the cell(s). An example of the insulating layer is a porous polymer layer, e.g., as depicted in example 500 or 550. In the volume of the dynamic insulator, (a) a physical disposition of the insulating and / or (b) a chemical type of the insulating material, may be configured to allow the electrolyte to occupy (e.g., and flow in) part of the volume at certain condition(s) in which the battery is found it, e.g., in the normal conditions comprising during use or during its storage, of the battery. The dynamic insulator may be configured to allow charge carriers (e.g., metal ions), and optionally also the electrolyte, to pass through the volume of the dynamic insulator at the normal condition(s), e.g., pass through the volume in which the insulating material is disposed. In an example, the dynamic insulator comprises a semisolid material (e.g., gel), or a solid (e.g., a hardened material), occupying the volume. In an example, the dynamic insulator comprises a particulate material occupying the volume, e.g., Fig. 6, 600. The insulating material may be in the form of a scaffold, or a matrix, in the volume, e.g., Fig. 6, 650. The insulator may comprise a portion devoid of the insulating material, e.g., also referred to herein as the “void fraction.” The void fraction may be at least about 5%, 10%, 20%, or 30% of the volume of the insulator. The void fraction may be at most about 35%, 30%, 20%, 10%, of the volume of the insulator. The void fraction may be at between any of the aforementioned percentage values, with respect to the volume of the insulator, e.g., from about 35% to about 5%, or from about 10% to about 30%. The electrolyte may be disposed in the volume, e.g., in a space between the insulating material portions disposed in the volume of the insulator. The insulating material may or may not be porous, e.g., a particulate material of the dynamic insulator may be porous. The electrolyte in the volume of the dynamic insulator may facilitate conduction of the charge carriers. The dynamic insulator may be included in the battery, e.g., an integral and / or internal, component of the battery. The dynamic insulator may or may not be disposed in the dividing space, if present in the battery. The battery may include a housing comprising one or more cells, and a dynamic insulator may contact one or more sides of the cell. The dynamic insulator may contract the interior face(s) of the housing. The cell may be immersed in the electrolyte. The electrolyte may be disposed (a) between the electrodes, (b) in each of the electrodes such as in a space unoccupied by the material(s) forming the electrode, (c) in the separation space, (d) as part of the dynamic insulator, (e) in a space separating one cell from itsimmediately adjacent cell, or (f) any combination thereof. In normal operation of a cell, the current passing from one electrode to its opposing electrode, mainly passes through the separation space (and through the separator), with a residual current passing through the volume occupied by the dynamic insulator.
[0085] Fig. 6 shows schematic examples of insulators. In example 600, particulate matter comprising the insulating material, including particle 601, is disposed in electrolyte 602. In example 600, matrix 651 comprising the insulating material, is immersed in electrolyte 652.
[0086] In some cases, the cell experiences an ESC event when the cell is charged. During the ESC event, a larger electrical current (e.g., load current) passes between the opposing electrodes of the cell (e.g., between the cathode and the anode), e.g., during the ESC event, a larger number of charge carriers (e.g., Li+) pass through the separator and between the opposing electrodes through the separation space, e.g., from the anode to the cathode. Larger is compared to operation under the normal conditions. After consent of the ESC event, (e.g., eventually,) heat from the larger current may cause the separator to “shutdown,” blocking much of the ionic conductivity between the opposing electrodes, e.g., between the anode and the cathode. For example, there is a substantial reduction (e.g., cessation) of the load current. During the ESC event, a smaller electrical current can pass between the opposing electrodes (e.g., between the cathode and the anode); and (e.g., simultaneously) the charge carriers (e.g., Li+) can pass through the dynamic insulator (e.g., electrolyte therein) contacting the opposing electrodes of the cell. The smaller electrical current may be referred to herein as the “residual current”). The smaller (residual) current may be effectuated by the charge carriers passing through the insulator, unless the insulator curtails such passage, e.g., at least during the ESC event. The dynamic insulator can contact at least one side of the electrode, e.g., can contact at opposing side of the electrodes (e.g., at a direction normal to, or substantially normal to, the separation space), e.g., see Fig. 2, 200. In an example, the separator shut down may cause the larger current between the opposing electrodes of the cell to diminish, e.g., substantially and / or measurably cease. The shutdown in the current load may be due to one or more components in the separation space undergoing a change due to a triggering event occurring during the ESC, e.g., any triggering event disclosed herein. Without wishing to be bound to theory, the shutdown of the separator may be at least in part due to partial, or due to complete, melting of a material (e.g., physical, and / or chemical change) of the separator, e.g., at least in part due to the elevated temperature occurring during the increased heat. Without wishing to be bound to theory, the shutdown of the separator may be at least in part due to partial or complete melting of the separator, e.g., at least in part due to the elevated temperature during the increased heat. The increased heat may be caused at least in part by passing of the larger electrical current between the opposing electrode and through the separation space. The residual current maybe propagating between opposing electrodes of the cell at the side of the electrodes, e.g., through the insulator. The insulator may or may not contact the separation space. At the side of the electrodes (e.g., electrode ends), the residual current propagates in a path from one electrode to its opposing electrode in the cell, and through the volume of the dynamic insulator contacting the two electrodes, e.g., see Fig. 2, 201. In such scenario, even though the separator will “shut down” to prevent an adverse effect caused by the load current (e.g., Fig. 2, 206), the adverse effect may occur at least in part due to flow of the residual current, which may trigger a runaway (e.g., exothermic) reaction causing the cell (e.g., and the battery) to adversely heat up, e.g., Fig. 1, 113. The adverse effect(s) may be adverse to the cell, to the battery, and / or objects disposed in the environment outside of the cell, whether animate or inanimate. The adverse effect(s) may be any of the ones disclosed herein. Outside of the cell can comprise outside of the battery housing, e.g., in an ambient environment. The adverse effect(s) may be defined according to jurisdictional definition where the battery is manufactured, stored, used, and / or otherwise located in. It may be advantageous to curtail (e.g., prevent) the occurrence of such adverse effect(s), e.g., using the dynamic insulator. In some embodiments, the present disclosure provides solutions to curtail the adverse effects. In some embodiments, the present inventions relate to method(s) (e.g., technique), device(s), apparatus(es), system(s), and design(s), which build a battery comprising cell(s). The battery may be configured to curtail the adverse effects, e.g., at least in part by shutting of the residual current and / or the load current which is in normal operation the main current of the battery.
[0087] In some embodiments, disclosed herein is a battery that uses a dynamic insulator comprising a material type (e.g., a polymer and / or a resin) to substitute at least a portion of the ceramic (e.g., aluminum oxide) in the insulator. The volume of the dynamic insulator may be referred to as a “porous volume,” or a “porous layer.” The dynamic insulator may be disposed on one or more faces of the cell. The face(s) of the cell may comprise opposing faces of the cell. The opposing faces of the cell may be opposing XY faces of a cell, opposing ZY faces of the cell, and / or opposing XZ faces of the cell. The dynamic insulator may be disposed in a volume in which residual current would flow when the dynamic insulator may be substituted by an insulator not susceptible to the triggering event, e.g., event triggered during the ESC. In some embodiments, the material type of the dynamic insulator is configured to be electrically insulating. In an example, the porous layer (the dynamic insulator) comprises a material type configured for electrical insulation. The degree of the electrical insulation of the dynamic insulator may be triggered by the triggering event, e.g., may be temperature dependent. The degree of electrical insulation of the dynamic insulator may depend on the triggering event, e.g., on the temperature of the dynamic insulator. The triggering event may cause the dynamic insulator to curtail its ability toconduct electrical current. The degree (e.g., rate) in which the charge particles flow in the dynamic insulator may depend on the triggering event, e.g., on the temperature. The dynamic insulator may comprise a polymer or a resin. One or more components of the dynamic insulator may have at least one material characteristic configured to be altered on the occurrence of the triggering event, e.g., beyond a threshold. In an example, the dynamic insulator may undergo a structural change (e.g., melt) above a temperature threshold. The material characteristic(s) depending on the triggering event(s) (e.g., on a threshold thereof) may comprise a change in a physical state of material, e.g., melting, or solidifying. The material characteristic(s) may depend on a threshold of the triggering event(s). The material characteristic(s) may comprise a change in the viscosity of a fluid material in the dynamic insulator, e.g., a chance in the viscosity of the electrolyte in the dynamic insulator. The change in material characteristic(s) may comprise a physical change or a chemical reaction. The change in material characteristic(s) may comprise binding, gelling, melting, or any combination thereof. Binding may comprise alteration of covalent bonds, ionic bonds, hydrogen bonds, and / or polar bonds. The alteration may comprise cross linking within a molecule (e.g., polymer strand), or between molecules (e.g., polymer strands), e.g., to form a matrix such as a gel. In an example, at least one component of the dynamic insulator may comprise cross branching. The physical shape (e.g., extent) of the molecule in the dynamic insulator may be temperature dependent. The polymer particles may have a (e.g., substantially) similar size and shape. The polymer particles may have a (e.g., substantially) homogenous size and / or shape distribution. The size and / or shape distribution of the particle may be a bell shape. In some embodiments, the dynamic insulator comprises a particulate material configured to be electrically insulating. The dynamic insulator and the separator may have at least one material type of the same type, e.g., and the material type may be different than the electrolyte. The dynamic insulator and the separator may differ by at least one material type. The particulate material of the insulator is configured to have similar (e.g., substantially the same, or the same) susceptibility to the triggering event as that of the (e.g., polymer) separator, e.g., same triggering event threshold. In some embodiments, the particulate material is configured to have similar (e.g., substantially the same, or the same) thermal properties as that of the (e.g., polymer) separator. The susceptibility of the dynamic insulator to the triggering event may allow inducing shutdown of the (e.g., alternate) residual current pathway. The susceptibility of the dynamic insulator to the triggering event may reduce an overall heating of the cell during an ESC event. The susceptibility of the dynamic insulator to the triggering event may curtail (e.g., prevent) one or more of the adverse effects. Such properties of the dynamic insulator may improve the overall safety of the cell and / or of the battery. The heating may comprise joule heating, e.g., resistive, or ohmic, heating in which heat is generated at least in part due to the resistance encountered by anelectric current passing through a conductor. In an example, the porous layer formed by the polymer particles (the dynamic insulator) is also electrically insulating and allows for ionic conduction and has similar thermal properties as the polymer separator. In an example, one or more of the properties of the dynamic insulator allow for inducing shutdown of this alternate current pathway, reducing the overall Joule heating of the cell during an external short circuit and improving safety.
[0088] In some embodiments, the dynamic insulator comprises a particulate material, e.g., as disclosed herein. The particulate material may have a size distribution. The particulate material (e.g., powder) may have central tendency (e.g., average) of a FLS (e.g., diameter) of at least about 1.5 micron (pm), 2.5 pm, 3.5 pm, 5 pm, 8 pm, 10 pm, 12 pm, or 15 pm. The particulate material (e.g., powder) may have central tendency (e.g., average) of a FLS (e.g., diameter) between the aforementioned values, e.g., from about 1.5 micron (pm) to about 15 pm, or from about 1.5 pm, to about 12 pm. The central tendency (e.g., median particle size - SD50) of the particulate material of the dynamic insulator may be between the aforementioned values, e.g., from about 3.5 pm to about 5 pm, from about 5 pm to about 12 pm, or from about 7 pm, to about 19 pm. The size distribution may assume a bell shape. The shape of the particles may comprise spherical, rod-like, or disk-like. The particulate material may have (e.g., substantially) spherical particles. The particulate material may comprise amorphous particles. Particles of the particulate material may have a (e.g., substantially) similar size and / or shape. The polymer particles may have a homogenous size and / or shape distribution. In some embodiments, the dynamic insulator comprises a particulate material configured to be electrically insulating. The particles may be generated by a process comprising melt mixing and grinding, spray drying, or precipitation and drying.
[0089] As shown in the examples of Figs. 7-9 and discussed herein, an example of a (e.g., secondary) battery uses aluminum oxide (“alumina” or AO) to create a dynamic insulator (also herein “porous layer”) on both XY faces of a cell. During an external short circuit (ESC) of a charged battery, a larger electrical current (also herein “load current”) passes between the electrodes (e.g., between the cathode and the anode). Simultaneously, charge carriers such as lithium ions pass through the separation space (e.g., and through the separator) while traveling from the anode to the cathode. In some examples, (e.g., eventually), the heat from the large (load) current causes the separator to “shutdown,” blocking much of the ionic conductivity between the anode and the cathode. However, at the Z end of the electrodes, there is still a current path through the porous AO. As shown in FIGS. 7-9, some examples of (e.g., secondary) batteries have a “horizontal” arrangement, which means that there is a much larger path for such side (e.g., edge) current (e.g., residual current) as compared to the residual current in a wound cell configuration (e.g., Fig. 1 , 115, and Fig. 3, 300), or “vertical” stacked cells (e.g., Fig. 3, 330) - this may result in a substantial (e.g., larger)residual current after shutdown as compared to other secondary cell architectures. The cells may be disposed in a pouch of the battery.
[0090] Fig. 7 shows a cross section of a battery comprising anode 702 comprising silicon and carbon (e.g., a composite of Silicon and carbon) coupled with current collector 701. The anode contacts separation space 705. One face of the separation space faces anode 702, and its opposing face faces and contacts cathode 703 comprising metal oxides (e.g., comprising lithium). Current collector 704 is coupled with cathode 703. The separation space (e.g., 705), extends beyond (e.g., outside) of the side (e.g., edge) of the anode, and bends 710a towards the anode’s interior. The anode contacts the separation space on its face, and a dividing space at its opposing face. The dividing space extends beyond the face of the anode that it contacts. The dividing space bends 710b towards the anode’s interior and towards the separation space. An insulator 706 (e.g., comprising alumina) contacts the sides (e.g., edges) of the cell, e.g., the sides (i) of the anode, (ii) of the cathode, (iii) of the separation space, and (iv) of the dividing space. Separation space 705, 710a, and dividing space 710b, are (e.g., substantially) identical e.g., in terms of their material content and / or general physical dimensions. Particulate material is depicted in anode 702, in cathode 703, and in insulator 706. In the example shown in Fig. 7, the dividing space and the separation space (e.g., substantially) mirror each other, along an axis running through a long axis of the anode depicted in Fig. 7, e.g., along the current collector of the anode disposed along the long axis. The Dividing space and the separation space are separated from each other by gap 710c. The dividing space divides one battery cell from another. The dividing space may comprise (e.g., substantially) the same material as the separation space. In the example shown in Fig. 7, the battery comprising cells arranged in a ABCS repeating arrangement, wherein A=anode, B=separation space, C=cathode, and S=dividing space. In the example shown in Fig. 7, the anode has a cross section that is longer than the cross section of the cathode, the thickness being in a direction substantially perpendicular to the long axis of the cathode depicted in Fig. 7.
[0091] Fig. 8 shows a cross section of a battery comprising anode 802 comprising silicon and carbon (e.g., a composite of Silicon and carbon) coupled with current collector 801. The anode contacts separation space 805, e.g., comprising a separator. One face of the separation space faces anode 802, and its opposing face faces and contacts cathode 803 comprising metal oxides (e.g., comprising lithium). Current collector 804 is coupled with cathode 803. The separation space (e.g., 805), extends beyond the side (e.g., edge) of the anode, and bends 810a towards the anode’s interior. The anode contacts the separation space on its face and contracts a dividing space at its opposing face. The dividing space extends beyond the face of the anode that it contacts. The dividing space bends 810b towards the anode’s interior and towards the separation space. An insulator 806 (e.g.,comprising alumina) contacts the sides (e.g., edges) of the cell, e.g., the sides of the anode, of the cathode, of the separation space, and of the dividing space. Particulate material is depicted in anode 802, in cathode 803, and in insulator 806. In the example shown in Fig. 8, the dividing space and the separation space (e.g., substantially) mirror each other, along an axis running through a long axis of the anode depicted in Fig. 8, e.g., along the current collector of the anode disposed along the long axis. The Dividing space and the separation space are separated from each other by gap 810c. The dividing space divides one battery cell from another. The dividing space may comprise (e.g., substantially) the same material as the separation space. In the example shown in Fig. 8, the battery comprising cells arranged in a ABCS repeating arrangement, wherein A=anode, B=separation space, C=cathode, and S=dividing space. When excessive load current and / or heat is experienced in the battery cell, the load current shuts off 808. Without wishing to be bound to theory, this may be due to changes occurring in the separation space such as clogging of the separator pores by a molten separator material. While load current 808 shuts off, residual currents 807a and 807b may continue to preside in the battery, e.g., when the insulator is not a dynamic insulator susceptible to the triggering conditions, or triggering event, e.g., of a runaway reaction.
[0092] Fig. 9 shows a cross section of a secondary battery cell having a dynamic insulator that was deposited as a polymer particle paste, the polymer particles being in the dynamic insulator volume 906 instead of non-dynamic insulator comprising a ceramic insulator such as aluminum oxide (AO), the paste utilized to create the insulator (also herein “porous layer”) on both XY faces of a cell, e.g., see Fig. 3, 350. The particles of the polymer particle paste have similar (e.g., substantially the same) size and shape as those of the ceramic (e.g., alumina = AO) paste. The porous layer formed by the polymer particles is (A) (also) electrically insulating, (B) allows for ionic conduction (e.g., at least in part by the electrolyte immersed in the volume of the dynamic insulator), and (C) has similar (e.g., substantially the same) thermal properties as the polymer separator. Once the separator shuts down (e.g., via melting), the polymer particle paste also shuts down (e.g., melt), effectively shutting down the (e.g., hypothesized) edge (e.g., residual) current pathway of the residual current.Shutting down may be with relation to a cessation of the current flow, e.g., to a substantial, material, and / or measurable degree. Material cessation of the current is such that the current may not be able to effectuate a requested / prescribed function effectuated by the current. For example, the melted polymer particles fuse and block the residual ionic conductance. In some embodiments, these properties of the dynamic insulator shown in the example of Fig. 9, allow for inducing shutdown of this alternate current pathway (e.g., the residual current pathway), such as by reducing the overall Joule heating of the cell during an external short circuit and improving safety.
[0093] Fig. 9 shows a cross section of a battery comprising anode 902 comprising silicon and carbon (e.g., a composite of Silicon and carbon) coupled with current collector 901. An anode contacts a separation space having bent portion 910a, e.g., comprising a separator. Another example of a separation space is 905. One face of the separation space faces anode 902, and its opposing face faces and contacts a cathode 903 comprising metal oxides, e.g., comprising lithium. Current collector 904 is coupled with cathode 903. The separation space (e.g., 905), extends beyond the side (e.g., edge) of the anode, and bends 910a towards the anode’s interior. The anode contacts the separation space on its face and contracts a dividing space at its opposing face. The dividing space extends beyond the face of the anode that it contacts. The dividing space bends 910b towards the anode’s interior and towards the separation space. A dynamic insulator 906 (e.g., comprising a polymer) contacts the sides (e.g., edges) of the cell, e.g., the sides of the anode, of the cathode, of the separation space, and of the dividing space. Particulate material is depicted in anode 902, in cathode 903, and in the dynamic insulator 906. In the example shown in Fig. 9, the dividing space, and the separation space (e.g., substantially) mirror each other, along an axis running through a long axis of the anode depicted in Fig. 9, e.g., along the current collector of the anode disposed along the long axis. The Dividing space and the separation space are separated from each other by gap 910c. The dividing space divides one battery cell from another. The dividing space may comprise (e.g., substantially) the same material as the separation space. In the example shown in Fig. 9, the battery comprising cells arranged in a ABCS repeating arrangement, wherein A=anode, B=separation space, C=cathode, and S=dividing space. When excessive load current and / or heat is experienced in the battery cell, the load current shuts off 908. Without wishing to be bound to theory, this may be due to changes occurring in the separation space such as clogging of the separator pores by a molten separator material. While load current 908 shuts off, residual currents 907a and 907b also shut off, e.g., as the dynamic insulator and the separator comprise (e.g., substantially) the same material susceptible to increased temperature. The alteration in the property / properties of the dynamic insulator due to the triggering event (e.g., elevated temperature) is schematically depicted as block 909. However, any portion of the dynamic insulator 906 experiencing the triggering event may experience the change.
[0094] Fig. 10 shows example of time dependent graphs showing voltage, current, and temperature of batteries. Graphs having solid line 1011 show batteries in which the cells are stacked in an arrangement similar to the one depicted in Fig. 13, 1300. The graphs having broken line 1012 show batteries in which the cell is rolled in a wound cell (e.g., jelly roll) type arrangement similar to the one depicted in Fig. 13, 1350, or Fig. 3, 300. The batteries utilized to generate the graphs in Fig. 10 do not have a dynamic insulator. The graphs 1011 are taken during discharging of the stacked cell battery experiencing an adverse effect. Whilethe voltage 1001 and current 1003 experience a significant drop (e.g., due to a load current shut down), the temperature 1005 of the battery significantly increases, e.g., due to flow of the residual current. The significant temperature increase may be due to a resulting runaway reaction. Without wishing to be bound to theory, the increase in the runaway reaction in the stacked cell configuration corresponding to 1011, may be at least in part due to an increased residual current as compared to the residual current in the jelly roll type battery corresponding to 1012. In the jelly roll type battery, while the voltage 1002 and current 1004 experience a significant drop (e.g., due to a load current shut down), the temperature of the battery remains substantially constant 1007, e.g., possibly due to the lower residual current as compared to the residual current.

The transition may comprise a three-dimensional (3D) reconfiguration, a cross linking, a gelling, or any combination thereof. The property change(s) may cause the charge carriers to alter (e.g., curtail) their propagation rate within the dynamic insulator, e.g., within a volume thereof.

At least one material type of the dynamic insulator may be configured to curtail (e.g., deter or reduce) the occurrence of, or curtail the degree of, the runaway reaction. In an example, at least one material type of the dynamic insulator is configured to curtail the degree of the heat generated in the battery to (e.g., substantially) equal the heat dissipating from the battery. In an example, at least one material type of the dynamic insulator is configured such that upon heating, the battery willreach a maximum temperature, e.g., steady state temperature or equilibrium temperature. The maximum temperature may be an equilibrium between heat dissipation from the battery and heat formation in the battery. The maximum temperature may be below one or adverse effects, e.g., substantial and / or material adverse effects such as any of the ones disclosed herein. The maximum temperature may be such that the heat generated by the battery is controllable, e.g., manageable. Controllable may be in an ambient setting, under reasonable effort, and / or under reasonable operation conditions such as allowed in the jurisdiction.

The dynamic insulator may curtail the heat generation in at least one component of the battery, e.g., and in the cell. Curtailing the heat generation may comprise deterring, slowing, halting, or stopping, that heat generation. The dynamic insulator may be configured to curtail propagation of the charge carriers through the dynamic insulator, e.g., from one electrode to its opposing electrode in a cell. The dynamic insulator may be configured to undergo a change in one or more material properties of material(s) of the dynamic insulator.

[0105] Fig. 11 shows a schematic example of process 1120 controlled using a control system in a feedback loop control scheme, e.g., in a closed loop control scheme. The control system receives set point 1105 to comparator 1106 that generates an error signal, which is fed 1145 into controller 1140. In other control systems, the comparator can be part of the controller. Controller 1140 generates a control signal that is fed into controlling element 1130. The controlling element may comprise a mechanism utilized for its control function to control process 1120. Controlling element 1130 provides an input to process 1120.

Battery cell 1352 is disposed (e.g. located) in battery housing 1351.
[0114] Example 1 : In an isolated environment comprising clean dry air (CDA), rechargeable lithium ion batteries were tested at an ambient temperature of about 23°C, and five samples were tested at 55°C. The batteries had configuration similar to the one in Fig. 3, 300 and350. One of the batteries (resulting in a behavior of Fig. 10, 1011) included a stacked cell configuration similar to the one in Fig. 13, 1300 or Fig. 3, 350. Each of the batteries’ cells included (a) a non-dynamic insulator comprising alumina devoid of a separator type polymer, and (b) an anode being a silicon-based anode (Si-C). The silicon based anode comprised carbon. The cells of the battery being shown in Fig. 8. The other battery (resulting in a behavior of Fig. 10, 1012) included a wound cell (e.g., jelly roll) type battery similar to the one in Fig. 13, 1350, with the anode being a graphite anode. The temperature error range was + / -5°C. The test initiated after temperature was equilibrated, between 1-4 hours, inclusively. The batteries pointed away from each other to prevent accidental shorting. A thermocouple contacted the battery housing. Batteries were attached to wires, and current was cycled through the batteries. Voltage, current, and temperature, were recorded as depicted in Fig. 10. The batteries were exposed to preconditioning charge and discharge cycles at maximum and minimum temperatures, the circuit was verified as open, the circuit resistance was verified at 80 + / - 20 mli-ohms, the cells were connected to an open circuit utilized for the short. The measuring conditions per temperature and voltage were established, after stabilization of the temperature, data acquisition initiated at 0.12 second intervals. The circuit closed to establish short. Temperature was monitored to detect any peaks, e.g., evidence of a thermal runaway. After a prescribed time lapsed and / or temperature threshold obtained, the circuit was opened, to stop the short and allow the cell to reach ambient temperate, e.g., within 10°C. Without wishing to be bound to theory, the differences observed between the graphs of the stacked cell type corresponding to Fig. 10, 1011 , and those corresponding to the jelly roll cell type corresponding to Fig. 10, 1012, may be due to (a) the surface area of the sides (e.g., edges) of the cell set in the stacked cell battery being substantially larger that the sides (e.g., edges) of the jelly rolled cell, (b) the number of cells in a stacked cell battery being substantially larger than in the jelly roll battery, (c) the surface area of the cathode-anode junctions on the side (e.g., edge) of the stacked cell battery being substantially larger than in the jelly roll battery, or (d) any combination thereof,
