Background Art

[0005] Lead-acid batteries are well known. Lead-acid batteries are composed of lead plates and separate lead dioxide plates, wherein the lead plates and the separate lead dioxide plates are immersed in an electrolyte solution. The chemical reaction caused by the lead, lead dioxide and electrolyte can release electrons, which then flow through the conductor to generate electrical energy.

[0006] One type of lead-acid battery is the AGM or absorbed glass mat lead-acid battery, which is a sealed (maintenance-free) battery in which the electrolyte is absorbed and retained on a mat that is wrapped around a current collector or grid. Currently known AGM batteries use lead alloy grids in a straight line grid pattern. Some of these grids may be spirally wound. These grids and corresponding batteries have many disadvantages. Summary of the invention

[0007] Thus, an improved grid for a lead-acid battery is disclosed. In one or more embodiments, the grid is for an AGM lead-acid battery. The grid comprises opposing upper and lower frame members, opposing first and second side frame members, and a plurality of radial grid wires, wherein the grid may be composed almost entirely of lead. In various examples, the grid may be composed almost entirely of raw lead or high purity lead or highly purified recycled lead.

The electrochemical cells are composed of a plurality of positive plates, a plurality of negative plates, an adsorbent glass fiber mat, and an electrolyte, each positive plate including a positive grid and a positive paste on the positive grid, each negative plate including a negative grid and a negative paste on the negative grid, the adsorbent glass fiber mat being interlaced between each positive plate and each negative plate, and the electrolyte being retained by the adsorbent glass fiber mat. Each of the positive grid and the negative grid includes a frame, the frame including an upper frame element including a current collecting flange, a first side frame element, a second side frame element, a lower frame element, and a plurality of grid lines arranged in a radial structure within the frame, the radial structure radiating from a radiating point located outside the frame boundary. A plurality of horizontal grids are interlaced with a plurality of grid lines arranged in a radial structure. Each of the positive grid and the negative grid is composed of raw lead or high purity lead or highly purified recycled lead.

[0009] A grid for an adsorbed glass fiber mat lead-acid battery is also disclosed. The grid comprises a frame, which is composed of an upper frame element having a current collecting flange, a first side frame element, a second side frame element, and a lower frame element. A plurality of grid lines are distributed in a radial structure within the frame, and the radial structure radiates from a radiating point outside the frame boundary. A plurality of horizontal grid lines are interlaced with a plurality of grid lines arranged in a radial structure. The grid is composed of raw lead or high-purity lead or highly purified recycled lead.

[0010] A perforated battery grid is also disclosed. The grid is made of raw lead or high purity lead or highly purified recycled lead and includes a plurality of grid wires arranged in a pattern throughout a frame structure. The pattern is a pattern of grid wires radiating from a radiating point, wherein the radiating point is located outside the frame boundary.

[0025] Reference Figure 1, wherein a battery 100 is disclosed, in particular a rechargeable battery, such as a lead-acid battery. According to one or more embodiments, the battery 100 is a lead-acid battery. The lead-acid batteries of various embodiments can be sealed (e.g., maintenance-free) or unsealed (e.g., wet). According to one or more embodiments, the lead-acid battery 100 is preferably a sealed lead-acid battery or an AGM lead-acid battery, and therefore may contain an absorbed glass mat (AGM). Although specific examples are described or shown, the battery 100 can be any type of secondary battery suitable for a particular purpose.

[0026] according to Figure 1-2 , the lead-acid battery 100 includes several battery cells or electrochemical cells 102, which are arranged in different compartments of a container or housing 104 containing an electrolyte. A cover 106 or cover is provided for the housing 104 (see Figure 1 ), and in various embodiments, the cover 106 includes the battery terminals 108 (e.g., the positive terminal 134 and the negative terminal 136). In one or more preferred embodiments, the cover 106 seals the housing 104. The battery housing 104 or the cover 106 may also include one or more filler hole caps 110 ( Figure 4 ) and / or ventilation assembly 112 ( Figure 1 ).

[0027] The description provided herein for purposes of example relates to automotive applications, where a stack of eight to twenty electrode plates 114, 116, including positive and negative electrodes, is used in each of six stacks or groups or blocks 112 in a 12-volt automotive battery to form an electrochemical cell 102. It should be understood that the grids disclosed herein, as discussed in detail below, may be used in applications where, as a non-limiting example, any six to thirty-one plates 114, 116 may be used in a stack 112. The number of stacks or groups of plates may also vary. It will be apparent to one skilled in the art, after reading this specification, that the size and number of plates 114, 116 (including the size and number of corresponding grids) in any particular stack, and the number of stacks 112 used to construct the battery 100 may vary depending on the desired end use. Each electrochemical cell 102 may include one or more positive plates 114 and one or more negative plates 116, and preferably includes a plurality of positive plates 114 and a plurality of negative plates 116. Each plate 114, 116 is formed with a grid 118, 120, on which an active material 122, 124 is pasted (see Figures 8A-8B Each grid 118, 120 has a flange 126, 128 (see Figure 3 ,5,7). According to Figure 3-5, a separator material 130 is disposed between each positive plate 114 and negative plate 116. The separator material 130 may be an absorbent glass mat (AGM), and in one or more embodiments, the separator material may be wrapped around a portion of the positive plate 114 and the negative plate 116 or interlaced with / interlaced between one (or both) of the positive plate 114 and the negative plate 116. Thus, the battery or electrochemical cell includes a plurality of positive plates, a plurality of negative plates, an absorbent glass mat, and an electrolyte, wherein the plurality of positive plates each include a positive grid and a positive paste on the positive grid, the plurality of negative plates each include a negative grid and a negative paste on the negative grid, the absorbent glass mat is interlaced between each positive plate and each negative plate, and the electrolyte is retained by the absorbent glass mat in a battery container and / or otherwise disposed in a battery container.

[0028] The plurality of electrochemical cells 102 may be electrically connected, for example, electrically coupled in series or otherwise configured according to the capacity of the lead storage battery 100 (see Figure 2-4 ). One or more cast connecting straps or inter-cell connectors 132 electrically couple the flanges 126, 128 in the plate group 112 and other corresponding plate groups in the battery 100. One or more positive and negative terminals 134 and 136 are also provided. Depending on the battery design, these terminals 134 and 136 typically include portions that can extend through the cover 106 and / or the housing 104. It will be appreciated that there are a variety of possible terminal arrangements, including top configurations, side configurations, or corner configurations as are known in the art.

[0029] As indicated, the battery 100 includes a positive plate 114 and a negative plate 116, and each plate includes a grid 118, 120 that can support electrochemically active materials 122, 124. In the illustrated embodiment, the positive and negative plates 114, 116 are paste-coated electrodes or plates (see Figure 5 and 8A -8B). The paste-coated electrode includes grids 118, 120, described in detail below, which form a substrate and provide electrochemically active materials or pastes 122, 124 on the substrate. The grids, including positive grid 118 and negative grid 120, provide an electrical contact between the positive and negative active materials 122, 124, or provide a paste that can achieve the purpose of conducting current.

[0030] according to Figure 6-79-10, the positive grid 118 will be specifically described in the examples, but the description also applies to the negative grid 120. The grid includes a frame 138. As noted, the grid can be spread across the entire frame. To this end, the frame 138 includes an upper frame member 140, first and second side frame members 142, 144 and a lower frame member 146. The current collector flange 126 (or 128) can be integral with the upper frame member 140. The flange 126 (or 128) can be offset from the center of the upper frame member 140, or can be located at the center of the first or second side frame member 142, 144 or closer to the first or second side frame member 142, 144. The flange 126 (or 128) can also have a uniform width. Therefore, the battery grid frame 138 has a top, a first side, a second side and a bottom, wherein the top has a flange. The upper frame member 140 also includes an increased conductive portion 148 , at least a portion of which is directly below the flange, which can optimize current conduction of the flange 126 (or 128 ).

[0031] The battery grid 118 also includes grid wires 150, 152. The grid wires 150, 152 can be provided in a grid mesh, which is formed by a plurality of grid wires in a certain pattern in the frame 138. The grid mesh may include one or more grid wires 150 connected to the upper frame element 140. The grid mesh may also include one or more grid wires 150 connected to the first side frame element 142. The grid mesh may include one or more grid wires 150 connected to the second side frame element 144. The grid mesh may include one or more grid wires 150 connected to the lower frame element 146. The grid mesh may also include a combination of the foregoing parts, such as, but not limited to, one or more grid wires 150 connected to the upper frame element 140 and the side frame elements 142 or 144 or the lower frame element 146, or connected to the two side frame elements.

[0032] One or more grid wires 150 may increase in cross-sectional area along their length from top to bottom, or in one or more embodiments, may have a tapered shape.

[0033] The grid pattern of the battery grid may include one or more grid lines 150 arranged in a radial structure. Figure 6 , 9-10, the pattern of grid lines includes radially extending grid lines 150. In particular, the grid lines 150 extending from the upper frame element 140 in the frame are provided in a radial configuration. That is, a plurality of radially extending grid lines 150 extend downwardly from the upper frame element 140. The pattern of grid lines can be from a radiating point 154 (see Fig. 9) or more than one radiant point. In one example, the radiant point 154 (or several radiant points) is located outside the boundary of the frame 138 and preferably above the upper frame element 140. These radially extending wires 150 extend at different angles. For example, these radially extending grid wires 150 extend within an angle range "α" of about 0.5° to 26.5° from an imaginary line "x" perpendicular to the upper frame element 140. Variations suitable for this purpose are also acceptable.

[0034] In one or more embodiments, one of the radially extending grid wires 156 may be parallel to the side frame members 142, 144 (see Fig. 9 ). The remaining radially extending grid lines 150 extend radially from an imaginary intersection along an imaginary line "x" perpendicular to the upper frame member 140 or along a radius line of the radially extending grid lines 156 parallel to the side frame members 142, 144, i.e., a radiating point 154 located outside the frame 138. In the foregoing example, the radially extending grid lines 150 are closer to each other when moving from a position near the lower frame member 146 to a position near the upper frame member 140, and the radially extending grid lines 150 are more spaced apart when moving from the radially extending grid lines parallel to the side frame members to the first side frame member 142 or the second side frame member 144.

[0035] One or more of the plurality of radially extending grid wires 150 may also be connected to the side frame members 142 or 144. It is contemplated that one or more radially extending grid wires 150 may also be connected to the lower frame member 146. Figure 6 In the illustrated example, the radially extending grid wires 150 terminate at grid transverse wire members 152 (discussed below) prior to reaching the lower frame member 146. In the illustrated embodiment, a plurality of vertically spaced extending grid wires 158 are disposed between the associated grid transverse wire members 152 and the lower frame member 146.

[0036] In one or more embodiments, the grid further includes a plurality of grid transverse lines 152 in a grid line pattern. Figure 6 In the example shown in 9-10, these transverse lines include, for example, horizontal grid lines 152 extending from the first side frame member 142, for example, across the entire grid 118 to the second side frame member 144. These grid lines 152 can be spaced (e.g., horizontally spaced) and parallel to the upper and / or lower frame members 140, 146, and variations suitable for this purpose are also accepted.

[0037] according to Fig.10 In one or more embodiments, the pattern of grid lines also includes horizontal grid lines that extend partially through the grid. In particular, some of the horizontal grid lines 160 are adjacent to each other and Fig.10 , located below the upper frame element 140. The partial horizontal grid line 160 extends from a node 162 near the side frame element 142 or 144, or from the side frame element 142 or 144, to a node 164 at a certain distance therefrom, and the node 164 is set at a certain internal position of the grid pattern. In the illustrated example, the grid line 160 extends to a position of approximately 1 / 4 to 1 / 3 of the width of the grid 118 and is located on the left side of the grid. Other variations are also acceptable without departing from the overall scope of the present invention. The partial horizontal grid line 160 divides each open space 172 into two open spaces 166 and 168.

[0038] The intersection or confluence of radially extending grid wires and grid transverse wires may (typically) occur at a node 170 - see also nodes 162, 164. Multiple such intersections or combined grid wires and grid transverse wires form a node 170. The combination of radially extending grid wires 150, vertical grid wires 158, grid transverse wires 152, 160 and / or nodes 162, 164, 170 forms one or more open spaces 172 or windows in the grid wire network carried by the frame 138. Thus, multiple grid wires can define a pattern that includes open areas or windows in the grid mesh and frame. In other words, multiple grid wires can be interconnected in each frame to create gaps. The open areas help retain active materials or pastes, which can be retained in the form of "pellets."

[0039] The pattern and corresponding shape of the grid wires can optimize the current carrying capacity of the wires to help convey the increased current generated from the location on the grid 118, 120 that is farthest from the flanges 126, 128 toward the location on the grid 118, 120 that is closest to the flanges 126, 128. In one or more embodiments, the width and spacing of the wires, such as the width and spacing of the wires 150, 152 located between the side elements 142, 144, can be predetermined to have substantially equal potential points across the width of the grid 118, 120. The width of the grid wires can increase near the flanges 126, 128. The number and size of the grid wires can also increase from the bottom to the top of the grid 118, 120. In addition, the size of the open area 172 in the grid mesh can be reduced in the area near the flanges 126, 128 (i.e., the area of ​​the open area farther from the flange or below the grid is larger than the open area closer to the flange or above the grid in the pattern). Likewise, the number of open areas 172 or windows in the grid web may be increased in areas near the flanges 126, 128 (i.e., there may be more open areas in the pattern closer to the flanges or above the grid than there may be open areas farther from the flanges or below the grid). In this regard, the size of the windows or open areas 172 may also vary between the grids 118, 120, and thus, depending on the number and size of the vertically extending or radial grid wires 150, the size and number of the windows 172 may provide more lead at or near the top of the grid. Additionally, some of the radial grid wires 150 may extend directly below the enlarged conductive portion 148 in the upper frame element 140, which may, for example, provide increased conductivity and efficiency to the grid.

[0040] In one non-limiting example, such as shown herein, the grids 118 , 120 may include approximately 30 to 40 radially extending grid wires 150 and approximately 10 to 15 transverse grid wires 152 , and more preferably approximately 34 or 35 vertical grid wires 150 and approximately 11 or 13 transverse grid wires 152 .

[0041] A particular grid pattern is shown and described for exemplary purposes only. It should be understood that variations thereof, such as but not limited to, the thickness, number, and orientation of the grid wires, will not exceed the overall scope of the present invention.

[0042] In some embodiments, it is desirable to reshape or refinish or deform or otherwise modify the grid, including one or more frame elements, grid wires and / or nodes, although this is not required. For example, the cross-section can be any cross-sectional design, including, but not limited to, approximately elliptical, approximately rectangular, approximately rhombus, approximately parallelogram, approximately hexagonal and / or approximately octagonal. It is to be understood that these shape terms are only roughly used to determine the overall cross-sectional shape, and the actual cross-section of the grid wires or nodes or frame elements may differ from the claimed shape, for example due to the precision of the processing process. Deformation of the grid wires is preferably provided to, for example, improve paste adhesion.

[0043] According to one or more embodiments, the grid material can be made of raw lead (Pb) (e.g., lead in an ore), or high purity lead, or highly purified recycled lead, or substantially pure lead or raw lead, which provides a variety of advantages over current devices. However, it is understood that recycled or recovered lead may also be used as long as the requirements herein are met. In various examples, the grids 118 and / or 120 are composed of 99.9-99.99% pure lead (Pb). It is also contemplated that other materials may be added to the grid material to meet the requirements herein.

[0044] Both the positive grid 118 and the negative grid 120 can be made of the same material and have the same or similar pattern. To this end, each battery grid 118, 120 can be a complete frame grid composed of raw lead or high purity lead or highly purified recycled lead or substantially pure lead and raw lead, including upper and lower frame elements 140, 146 and first and second side frame elements 142, 144 surrounding the grid mesh or other types of patterns described herein. However, it is expected that this pattern will also vary between the positive grid 118 and the negative grid 120.

[0045] The thickness of each grid 118, 120 can be varied according to the required manufacturing and performance parameters. For example, the thickness can be determined according to the minimum manufacturing requirements or the minimum paste adhesion requirements or other suitable parameters. The grid in one or more embodiments is perforated to form the pattern described herein. The result of the perforation process can form a unique grid structure. Although a perforated grid or perforation process is specifically described, it should be understood by those skilled in the art that there are a variety of grid forming methods, and it is expected that any one or more methods can be adjusted to form a grid that can achieve the goals here. According to one or more examples, the grid material can include a minimum thickness. Advantageously, according to one or more specific examples described herein, the grids 118, 120 can be reduced in thickness relative to commercial perforated battery grids. Similarly, the weight of the grid, and the final weight of the battery can also be changed. For example, by reducing the lead content in the grids 118, 120, the total weight of the grid and therefore the total weight of the battery containing one or more such grids is reduced. In one embodiment, the positive and negative grids 118, 120 can be formed with different thicknesses. However, it is desirable that the positive and negative grids 118, 120 may be designed to be the same thickness. As a non-limiting example, the thickness of the grids 118, 120 ranges from approximately 0.5 mm to 1.0 mm. In another example, the thickness of the positive grid 118 may be approximately 0.8 mm, while the thickness of the negative grid 120 may be approximately 0.7 mm. The thickness of the grids 118, 120 themselves may be different (e.g., the thickness of the side frame compared to the thickness of the grid wire). For example, in another embodiment, the width of the side frames 142 and / or 144 ranges from approximately 2 mm to 6 mm. In one or more embodiments, the grids 118, 120 may be provided with a height range of approximately 130 mm to 140 mm, and a width range of approximately 140 mm to 150 mm. Although specific examples are provided for illustrative purposes, changes may be made to the specific examples to provide grid sizes that are suitable for specific applications.

[0046] A variety of methods for forming or manufacturing lead-acid batteries are known, any of which may be used. One example of a method for forming or manufacturing battery 100 is described in U.S. Pat. No. 9,379,378, which is incorporated herein by reference in its entirety. As described above, the corresponding grid for battery 100 may be perforated according to known methods for implementing the method.

[0047] According to the illustration and description herein, a novel battery grid 118, 120 is provided, which has many advantages. The battery grid can be a perforated battery grid and has a plurality of grid lines arranged in a certain pattern in the frame, which is a grid line pattern that radiates from a radiating point, wherein the radiating point is located outside the frame boundary and preferably above the upper frame element. The battery grid provides a strong frame to maintain the strength of the grid to reduce the possibility of premature fatigue failure and provide improved manufacturing characteristics. In addition, the radial pattern described can optimize power distribution, transmission and recharging.

[0048] Advantageously, in some embodiments, a single stamped or punched grid may be selectively used for both the positive electrode and the negative electrode to reduce the need for two different molds and reduce manufacturing costs. In addition, such a grid includes a complete frame (e.g., including an upper frame element, a lower frame element, and a side frame element) to increase the strength of the positive and negative grids and reduce the possibility of perforation of the separator or glass fiber mat due to wire exposure. In addition, the flat plate design described herein provides more grid integrity (strength) for ease of processing and operation. Moreover, the grid transverse wires can extend across the entire grid (e.g., the entire width of the grid), which increases the structural strength of the grid and allows the use of the grid materials described herein (also reducing the width of the grid in some examples). In addition, in one or more embodiments, the grid provided herein has improved manufacturing performance, that is, the grid is easier to apply with paste. In one example, adding a partially horizontal grid wire to the grid can make the grid easier to apply with paste during the manufacturing process.

[0049] The battery 100 described herein may be used or provided for any suitable purpose. Advantageously, the battery grids 118, 120 and battery 100 disclosed herein are effective for both SLI ("starting", "lighting", "ignition") and deep cycle applications. One or more particular examples include vehicles, such as automobiles, motorcycles, buses, recreational vehicles, boats, golf carts, etc. The battery 100 can be configured to provide at least a portion of the energy required to start or operate a vehicle or vehicle system (e.g., starting, lighting, and ignition systems). In addition, it should be understood that the battery 100 can be used in a variety of applications that do not include vehicles, and all of these applications are within the scope of the present disclosure.

[0050] As used herein, the terms "approximately," "almost," "substantially," and similar terms have a broad meaning and are consistent with the usage commonly used and accepted by those of ordinary skill in the art to which the subject matter of the present disclosure belongs. Those skilled in the art should understand after perusing this disclosure that these terms are intended to describe certain features described and claimed, rather than to limit the scope of these features to the precise numerical ranges given. Therefore, these terms should be interpreted as indicating that non-essential or insignificant modifications or variations of the subject matter described and claimed are considered to fall within the scope of the present invention as described in the appended claims.

[0051] It should be noted that references to relative positions (e.g., "above" and "below") in the specification are only used to determine the orientation of various elements in the drawings. It should be recognized that the orientation of a particular component can vary greatly depending on the application in which it is used.

[0052] For purposes of this disclosure, the term "connected" means that two components are directly or indirectly connected to each other. Such connection may be fixed or removable in nature. Such connection may be achieved by the two components or by the two components and any additional intermediate components (the additional intermediate components form a single unified whole with each other or with the two components), or by the two components and any additional intermediate components (they attract each other). Such connection may be permanent in nature or removable or releasable.

[0053] It is also important to note that the construction and arrangement of the systems, methods, and devices shown in the various embodiments are illustrative only.
