Description

Batteries, electrical equipment and battery manufacturing processes Technical Field

[0001] This invention relates to the field of new energy battery technology, and in particular to a battery, electrical equipment, and battery manufacturing process. Background Technology

[0002] Traditional steel-cased rechargeable lithium-ion and sodium-ion batteries use the same steel casing and explosion-proof valve structure as the Panasonic 18650 battery. This type of battery has three main drawbacks when used in new electronic products: First, the positive and negative terminals are on opposite sides, often requiring soldering to align them, which increases solder joints and resistance. Second, the battery lacks a support structure when connected to electronic products, requiring an external bracket for fixation. Third, a protection board needs to be soldered to the circuit board to prevent short circuits, over-discharge, and over-charge. The complex soldering process and numerous solder joints increase the resistance of the electronic product, and the presence of cold solder joints increases product unreliability. The connection between the battery and the protection board and circuit board involves at least four solder joints and two lead wires. Each solder joint has a resistance of approximately 10mΩ, and each lead wire also carries resistance. The more solder joints and lead wires in the connection circuit between the electronic product and the battery, the greater the circuit resistance.

[0003] This current structure makes the design of rod-type detachable products very complex, with many solder joints, increased resistance in the circuit, and thus increased ineffective parts of the circuit, reducing the power of the effective parts of the circuit. Therefore, a new structure battery was designed that is easy to use in rod-type electronic products. Summary of the Invention

[0004] The technical problem to be solved by the embodiments of the present invention is that the positive and negative electrodes of traditional batteries are opposite, and the connection with electronic products requires welding for auxiliary fixation. This requires additional auxiliary fixing structures, increases solder joints and wires, and increases the resistance in the circuit, resulting in a complex product structure, larger size, and more ineffective resistance and heat generation in the circuit.

[0005] To address the aforementioned problems, this invention discloses a battery. This battery allows for contact-based connection with electronic products. The structure between the auxiliary fixing structure and the electrodes secures the battery and the main body of the electronic product together, eliminating the need for mechanical fixation via glue or screws. This reduces the number of solder points on the electronic product, thereby reducing the overall circuit resistance.

[0006] On one hand, the present invention provides a battery comprising a housing, a battery cell, and a first encapsulation member; the battery cell and the first encapsulation member are respectively disposed within the housing, the outer contour of the first encapsulation member is fitted with the inner wall of the housing, and the first encapsulation member is above the battery cell; the top of the first encapsulation member forms a groove with the inner wall of the housing; the first encapsulation member is made of insulating material, and the positive electrode of the battery cell passes through the first encapsulation member.

[0007] On the other hand, the present invention also provides a battery comprising a housing, a battery cell, and a second encapsulation component; the battery cell and the second encapsulation component are respectively disposed within the housing, the outer contour of the second encapsulation component is fitted with the inner wall of the housing, and the second encapsulation component is located above the battery cell; the top of the second encapsulation component forms a groove with the inner wall of the housing; the second encapsulation component comprises a circuit board and at least one conductive element, the conductive element being disposed on the top of the circuit board.

[0008] A further technical solution is that the second package further includes an insulating component, which is disposed on one side of the circuit board.

[0009] A further technical solution is that the inner wall of the housing is provided with a limiting part, and the second encapsulation member is disposed on the limiting part.

[0010] A further technical solution is that the housing is provided with a connection hole, which communicates with the groove.

[0011] A further technical solution includes a switch, which is disposed on the circuit board.

[0012] A further technical solution includes a protection chip, which is disposed on the circuit board.

[0013] In another aspect, the present invention also provides an electrical device comprising a battery as described in any of the above embodiments.

[0014] A further technical solution includes an atomizing component, which is electrically connected to the battery.

[0015] Furthermore, the present invention also provides a battery manufacturing process, comprising the following steps: S1, fabricating a battery cell and a second package, the second package comprising a circuit board and at least one conductive component, the conductive component being welded to the top of the circuit board; S2, placing the battery cell inside a housing, and welding / pressing the negative electrode of the battery cell to the bottom of the housing to obtain a first semi-finished battery; S3, subjecting the first semi-finished battery to baking and electrolyte injection processes to obtain a second semi-finished battery; S4, passing the positive electrode of the battery cell of the second semi-finished battery through an insulating material, and welding the circuit board to the positive electrode of the battery cell of the second semi-finished battery to obtain a battery.

[0016] Compared with the prior art, the technical effects achieved by the embodiments of the present invention include: the top of the first package and the inner wall of the housing form a groove, which can directly use the outer shell of the battery cell as the outer shell of the electronic product without the need for an additional outer shell, effectively improving the volume utilization rate, effectively simplifying the structure of the electronic product, increasing the overall product capacity and reducing production costs.

[0017] The positive terminal of the battery cell passes through the first encapsulation component to serve as the positive terminal of the battery. The casing is connected to the negative terminal of the battery cell, thus the casing serves as the negative terminal of the battery. This design reduces the number of solder joints, thereby lowering the overall circuit resistance of the product. Conductive components are mounted on a circuit board, which covers the battery cell. The circuit board acts as a rigid support layer, eliminating the need for an external protection board. This effectively integrates the battery's explosion-proof valve and protection board into one unit, significantly reducing production costs and increasing battery capacity.

[0018] The conductive components are mounted on the circuit board, which is then placed over the battery cell. The conductive components serve as the battery electrodes, avoiding the need for the circuit board to be connected to the positive and negative terminals of the battery separately via wires. This reduces the number of solder joints and thus lowers the overall circuit resistance of the product.

[0019] By mounting conductive components on a circuit board, which then covers the battery cell, the conductive components serve as the battery's electrodes. The battery functions as a separate module, and the functional components of the product function as separate modules, which can effectively improve the production efficiency of electronic products.

[0020] In existing solutions, the positive electrode of the battery cell passes through the circuit board as the battery electrode. In this solution, the positive electrode of the battery cell passes through an insulator. The positive electrode of the battery cell is soldered to the circuit board, and then the electrode of the circuit board serves as the battery electrode. Compared with the circuit board wrapping the positive electrode of the battery cell, the insulator wrapping the positive electrode of the battery cell has higher sealing performance and can effectively reduce the passage of electrolyte and gas through the gaps at the wrapping of the positive electrode of the battery cell.

[0021] The number of solder joints in the entire circuit of the atomizing device and battery has been reduced, thereby lowering the overall circuit resistance and improving the heating effect of the heating wire in the atomizing device.

[0022] This battery manufacturing process reduces the steps of soldering wires to the battery cell and circuit board separately, which can improve the production efficiency of the battery. The battery produced in this way uses conductive components and the casing as the battery electrodes, avoiding the connection between the circuit board and the battery electrodes through wires, reducing the number of wires and solder joints, and achieving the effect of reducing resistance.

Detailed Implementation

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Similar component reference numerals in the drawings represent similar components. Obviously, the embodiments described below are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0027] It should be understood that, when used in this specification and the appended claims, the terms "comprising" and "including" indicate the presence of the described features, integrals, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components and / or collections thereof.

[0028] It should also be understood that the terminology used in this specification of embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to limit the embodiments of the invention. As used in this specification of embodiments of the invention and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0029] Example 1 Referring to Figures 1-2, this embodiment of the invention provides a battery. The battery includes a housing 1, a battery cell 2, and a first encapsulation component; the battery cell 2 and the first encapsulation component are respectively disposed within the housing 1, the outer contour of the first encapsulation component is fitted into the inner wall of the housing 1, and the first encapsulation component is located above the battery cell 2; the top of the first encapsulation component forms a groove with the inner wall of the housing 1; the first encapsulation component is made of insulating material, and the positive electrode of the battery cell 2 passes through the first encapsulation component.

[0030] In this embodiment, the first encapsulation component and the housing 1 encapsulate the battery cell 2 to obtain a battery. The first encapsulation component is made of insulating material and rigid support material, typically a soft material encapsulating a rigid material, such as an explosion-proof valve. The housing 1 is a cylindrical structure with a one-way opening. The cross-section of the housing 1 can be any one of a circle, ellipse, or rhombus. It should be noted that the cross-sectional shape of the housing 1 being a circle, ellipse, or rhombus is merely an example. Those skilled in the art can also use housing 1 with other cross-sectional shapes, which will not exceed the protection scope of this invention. The first encapsulation component is installed at a certain height inside the housing 1, wherein the top of the first encapsulation component is lower than the top of the housing 1, forming a groove with the first encapsulation component as the bottom surface and the inner wall of the circuit board 3 as the enclosure. Let the opening side of the housing 1 be the top and the bottom of the housing 1 be the bottom. The battery cell 2 includes a packaged core and a wound core (also known as a semi-finished battery cell). The battery cell 2 is electrically connected to the circuit board 3, which includes a PCB board. The outer contour of the circuit board 3 fits into the inner wall of the housing 1, so that the circuit board 3 is mounted directly above the battery cell 2. The packaged core includes a lithium battery, sodium battery, or other rechargeable battery (i.e., a battery that can be recharged and reused). The depth of the groove formed between the top of the first package and the inner wall of the housing 1 ranges from 2mm to 35mm.

[0031] The depth of the groove can be adjusted according to different application scenarios: In one embodiment, when the battery is used as an internal component and an outer shell is needed to cover it, the groove depth can be selected as 2-5mm. In another embodiment, referring to Figure 4, the battery housing 1 and the outer shell 6 are two independent structures, with the outer shell 6 fitted onto the housing 1. In this embodiment, the battery housing 1 is appropriately extended to serve as the outer shell 6, that is, the battery housing 1 serves as the outer shell of the electronic product, and the entire product no longer needs the outer shell 6; the groove depth is 5-35mm, and different depths can be set according to different products. The greater the groove depth, the higher the stability of the connection between the housing 1 and the sealing connector 4 during product use; for example, when a handheld fan, shaver, or flashlight is placed on top of the battery, the groove depth is generally set to 10mm; when an atomizer is placed on top of the battery, the groove depth is generally set to 20mm, which can be adjusted according to the volume of the atomizing liquid. When the atomizer contains a large amount of atomizing liquid, the maximum depth can be set to 35mm.

[0032] The resistance generated by solder joints is generally between 8mΩ and 100mΩ. The resistance of solder joints is affected by the material and the soldering area. A good solder joint has a resistance of around 10mΩ. The positive terminal of cell 2 passes through the first package to serve as the positive terminal of the battery. The casing 1 is connected to the negative terminal of cell 2, so that the casing 1 serves as the negative terminal of the battery. This battery can reduce the number of solder joints, thereby reducing the overall circuit resistance of the product.

[0033] Preferably, cell 2 is a wound core, which is the core structure of a lithium battery cell. The wound core has no shell, encapsulation edges, tabs, or other non-active structural components; its volume / weight is entirely composed of active / functional components such as positive and negative electrodes, separators, and tabs. Compared to a packaged core of the same volume, it has a higher energy density. The wound core is a core semi-finished product in cell production, and its production only involves the core processes of electrode preparation and winding / stacking. Compared to a finished packaged core, it reduces packaging processes such as casing, tab welding, laser edge sealing / heat sealing, liquid injection, formation, and capacity testing. This reduces equipment investment, labor costs, and energy consumption costs in each packaging process, and also reduces yield losses in the packaging stage. In another embodiment, the shell 1 is made of conductive metal, and the bottom tabs of the wound core can directly conduct electricity through the shell 1, eliminating the need for lead wire structures at the bottom tabs and effectively preventing leads from occupying the internal space of the shell 1.

[0034] Preferably, when the battery cell 2 is a wound core, the casing 1 is made of a metal material, such as an aluminum casing or a steel casing. The battery prepared in this way has the effects of high energy density, strong adaptability to automated production, and low cost.

[0035] Referring again to Figures 1-2, in this embodiment, the first package includes an insulating element 8.

[0036] Specifically, the first encapsulation includes an insulating element 8, which is made of a soft insulating material. In this embodiment, the battery cell 2 is encapsulated in the housing 1 by the first encapsulation. It should be noted that the soft insulating material can serve as the sealing layer, insulating layer, and explosion-proof layer of the battery. The specific principle can be determined with reference to existing materials, and the present invention does not make specific limitations in this regard.

[0037] Furthermore, the inner wall of the housing 1 is provided with a limiting part 12, and the first encapsulation member is disposed on the limiting part 12.

[0038] Specifically, the limiting part 12 is a protruding structure on the inner wall of the housing 1. For example, one or more protrusions are provided at the same height on the inner wall of the housing 1 to form the limiting part 12. The limiting part 12 is used to support the first package. The battery cell 2 can be installed on the bottom of the housing 1 through the limiting part 12.

[0039] Furthermore, the housing 1 is provided with a connecting hole 13, which communicates with the groove.

[0040] Specifically, the groove is formed by the first encapsulation component and the housing 1. The connection hole 13 is provided on the housing 1. In one embodiment, the housing 1 serves as the negative electrode of the battery. The connection hole 13 is installed on the housing 1 around the groove. The electrical device can be fastened to the connection hole 13 to increase the connection strength and electrical connection.

[0041] Furthermore, the outer diameter of the housing 1 gradually decreases from top to bottom, or the outer diameter of the housing 1 is equal from top to bottom.

[0042] Specifically, the housing 1 is a cylindrical structure with its maximum outer diameter located at the opening, or the housing 1 is a cylindrical structure with a uniform outer diameter, which facilitates the insertion of the battery into the electronic product through the opening of the housing 1. The electronic products include: flashlights, atomizers, styluses, handheld fans, shavers, electronic candles, wireless headphones, etc.

[0043] Example 2 Referring to Figures 3-7, this embodiment of the invention provides a battery. The battery includes a casing 1, a battery cell 2, and a second encapsulation component. The battery cell 2 and the second encapsulation component are respectively disposed within the casing 1. The outer contour of the second encapsulation component fits into the inner wall of the casing 1, and the second encapsulation component is located above the battery cell 2. The top of the second encapsulation component forms a groove with the inner wall of the casing 1. The second encapsulation component includes a circuit board 3 and at least one conductive element, the conductive element being disposed on the top of the circuit board 3. The specific details of each component are as follows: In this embodiment, the casing 1 is a cylindrical structure with a one-way opening. The cross-section of the casing 1 is any one of a circle, ellipse, or rhombus. It should be noted that the cross-sectional shape of the casing 1 being any one of a circle, ellipse, or rhombus is merely an example. Those skilled in the art can also use casing 1 with other cross-sectional shapes, which will not exceed the protection scope of this invention. The opening side of the housing 1 is designated as the top, and the bottom of the housing 1 as the bottom. The battery cell 2 includes a packaged core and a wound core (also known as a semi-finished battery cell). The battery cell 2 is electrically connected to the circuit board 3, which includes a PCB board. The outer contour of the circuit board 3 fits into the inner wall of the housing 1, so that the circuit board 3 is mounted directly above the battery cell 2. The conductive component is a columnar structure made of conductive metal material or a conductive coating on the PCB, and is fixedly mounted on one side of the circuit board 3. In one embodiment, one conductive component is included, which serves as the positive electrode of the battery, and the housing 1 serves as the negative electrode of the battery. In another embodiment, multiple conductive components are included, and the multiple conductive components are fixedly mounted on the same side of the circuit board 3. In yet another embodiment, two conductive components are included, designated as the first conductive component 31 and the second conductive component 32, respectively. The first conductive component 31 and the second conductive component 32 serve as the positive and negative electrodes of the battery, respectively, for electrical connection with electronic products. The housing 1 may not be connected to the negative electrode of the battery cell 2. The second encapsulation component is installed at a certain height inside the housing 1, wherein the top of the circuit board 3 is lower than the top of the housing 1, forming a groove with the circuit board 3 as the bottom surface and the inner wall of the circuit board 3 as the enclosure. In one embodiment, the circuit board 3 is provided with a charging chip 2, which is a rechargeable battery cell 2, and the charging / discharging of the battery cell 2 is controlled by the charging chip 2. The battery fits into the electronic product through the groove, increasing the connection sealing and firmness. In one embodiment, the opening of the housing 1 is higher than the top of the conductive component, so that when the positive and negative terminals of the battery are connected or dropped, the positive and negative terminals of the battery are prevented from simultaneously contacting the conductor, thus avoiding short circuit and fire.

[0044] The resistance of solder joints is generally between 8mΩ and 100mΩ. The resistance of a solder joint is affected by the material and the soldering area. A good solder joint has a resistance of around 10mΩ. Conductive components are mounted on circuit board 3, which covers the battery cell 2. These conductive components serve as the battery electrodes. This avoids connecting circuit board 3 to the positive and negative terminals of the battery via wires, thus reducing the number of solder joints and consequently lowering the overall circuit resistance of the product.

[0045] Referring again to Figures 3-7, in this embodiment, the second package further includes an insulating member 8, which is disposed on one side of the circuit board 3.

[0046] Specifically, the insulating component 8 is made of a soft material and is installed at the bottom of the circuit board 3. In this embodiment, the battery cell 2 is encapsulated in the housing 1 by the insulating component 8. The insulating component 8 and the rigid PCB circuit board 3 together constitute a new explosion-proof valve. It should be noted that the soft insulating material can serve as the sealing layer, insulating layer, and explosion-proof layer of the battery. The specific principle can be determined by referring to existing materials. This invention does not specifically limit this. The PCBA serves as the strength support layer of the explosion valve. The circuit board 3 can prevent electrolyte leakage inside the battery and also act as a protection board to prevent over-discharge of the battery, thereby improving the battery's service life. The second encapsulation component obtained by the circuit board 3 and the insulating component 8 can replace the traditional explosion-proof valve. That is, the circuit board 3 can serve as the explosion-proof structure of the battery. Therefore, there is no need to weld an additional explosion-proof valve to the battery, thereby improving the battery's energy density and reducing the battery's resistance, effectively improving the battery's safety performance. Generally, when the battery cell 2 is a wound core, adding the insulating component 8 can effectively improve the battery's safety performance.

[0047] In one embodiment, the insulating element 8 is made of silicone gel, and the silicone gel is used to wrap the circuit board 3 to obtain the second encapsulation.

[0048] In one embodiment, when a core is selected for the interior, the insulating component 8 is made of a corrosion-resistant material, such as nitrile rubber, perfluoroether rubber, brominated butyl rubber, polyethylene terephthalate, polyimide, etc., and the second package is prepared by wrapping the circuit board 3 with the above materials.

[0049] Specifically, the limiting part 12 is a protruding structure on the inner wall of the housing 1. For example, one or more protrusions are provided at the same height on the inner wall of the housing 1 to form the limiting part 12. The limiting part 12 is used to support the insulating member 8 and the circuit board 3. The battery cell 2 can be installed at the bottom of the housing 1 through the limiting part 12. In one embodiment, the insulating member 8 is installed between the limiting part 12 and the circuit board 3.

[0050] Furthermore, the housing 1 is provided with a connecting hole 13, which communicates with the groove.

[0051] Specifically, the groove is formed by the second encapsulation component and the housing 1. The connection hole 13 is provided on the housing 1. In one embodiment, the housing 1 serves as the negative electrode of the battery. The connection hole 13 is installed on the housing 1 around the groove. The electrical device can be fastened to the connection hole 13 to increase the connection strength and electrical connection.

[0052] Furthermore, it also includes a switch, which is disposed on the circuit board 3.

[0053] Specifically, a switch is an electronic component that can open a circuit, interrupt current, or divert current to another circuit. Examples include push-button switches and proximity switches. In one embodiment, the switch includes an airflow sensor, forming an airflow sensing switch. When the user inhales, the airflow sensor (i.e., the microphone) responds, triggering the control circuit, and the atomizing device begins to operate, producing vapor. If the user stops inhaling, the airflow in the sensor disappears, the airflow sensor automatically shuts off, and the control circuit stops operating, ceasing vapor production. The specific principle of controlling the start and stop of components in the circuit via the airflow sensor can be determined with reference to existing literature; this invention does not specifically limit this aspect.

[0054] Furthermore, it also includes LED lights, which are disposed on the circuit board 3.

[0055] Specifically, the LED light is controlled to turn on and off via a switch. For example, in one embodiment, an airflow sensor is used as a switch, forming an airflow sensor switch. When the user inhales, the airflow sensor (i.e., the microphone) responds, triggering the control circuit, and the light turns on. If the user blows three times consecutively and the current stops, the airflow sensor automatically shuts off, the control circuit stops working, and the LED light turns off. The specific principle of controlling the start and stop of components on the circuit via the airflow sensor can be determined with reference to existing materials, and this invention does not specifically limit it.

[0056] Furthermore, it also includes a protection chip, which is disposed on the circuit board 3.

[0057] Specifically, the protection chip provides short-circuit protection, overcharge and over-discharge protection, and prevents reverse connection short circuits of the battery.

[0058] Furthermore, the outer diameter of the housing 1 gradually decreases from top to bottom, or the outer diameter of the housing 1 is equal from top to bottom.

[0059] Specifically, the housing 1 is a cylindrical structure with its maximum outer diameter located at the opening, or the housing 1 is a cylindrical structure with a uniform outer diameter, which facilitates the insertion of the battery into the electronic product through the opening of the housing 1. The electronic products include: flashlights, atomizers, styluses, handheld fans, shavers, electronic candles, wireless headphones, etc.

[0060] Furthermore, the conductive components are made of metallic materials.

[0061] Specifically, the conductive components are made of metallic materials, such as brass, phosphor bronze, beryllium copper, silver alloy, tungsten carbide, gold plating, silver plating, tin plating, and nickel plating.

[0062] The present invention also provides an electrical device comprising a battery as described in any of the above embodiments.

[0063] Furthermore, it also includes an atomizing component, which is electrically connected to the battery.

[0064] Specifically, the top of the circuit board 3 is provided with a first conductive element 31 and a second conductive element 32, which are the positive and negative electrodes of the battery, respectively, and the atomizing component is used to atomize the test liquid.

[0065] In one embodiment, the battery is further provided with a sealing connector 4, which is clamped between the atomizing component and the battery. The sealing connector 4 is provided with a conductive component. The first conductive component 31 and the second conductive component 32 of the battery are in contact with the bottom of the conductive component of the sealing connector 4, and the conductive component of the atomizing component is in contact with the top of the conductive component of the sealing connector 4, thereby realizing the electrical connection between the battery and the atomizing component.

[0066] Furthermore, it also includes a housing 6 and a cover 7, with the battery and the atomizing component respectively disposed inside the housing 6, and the cover 7 being detachably connected to the housing 6.

[0067] Specifically, the cover 7 is closed to the outer shell 6. In this embodiment, the cover 7 is provided with air holes, such as a mouthpiece, so that the user can inhale the atomized material. The cover 7 can be embedded in the outer shell 6. In one embodiment, the part of the cover 7 embedded in the outer shell 6 is also provided with protrusions and / or brambles to increase the tightness of the connection between the cover 7 and the outer shell 6.

[0068] Furthermore, the outer casing 6 is provided with an opening 61.

[0069] Specifically, the number of openings 61 is at least one. In one embodiment, multiple openings 61 are arranged to form a preset shape, enabling communication between the interior of the outer casing 6 and the exterior of the outer casing 6 through the openings 61. In one embodiment, a light-emitting device is provided on one side of the opening 61. For example, the light-emitting device is mounted on the battery and is used to emit light to indicate the battery's charge status. The light from the light-emitting device can be seen through the opening 61.

[0070] It also includes a sealing connector 4, which covers the opening.

[0071] Specifically, the sealing connector 4 is usually made of a soft material and is used to cover the opening of the housing 1. Typically, the sealing connector 4 is equipped with conductive holes and / or conductive elements. In one embodiment, the sealing connector 4 is equipped with at least two conductive elements, which are respectively connected to the first conductive element 31 and the second conductive element 32 on the circuit board 3. By covering the circuit board 3 with the sealing connector 4, the airtightness of the battery is improved, and the circuit board 3 is reinforced and protected to prevent the circuit board 3 from detaching from the housing 1.

[0072] Furthermore, the top of the circuit board 3 forms a groove with the inner wall of the housing 1, and the sealing connector 4 can be embedded in the groove.

[0073] Furthermore, the sealing connector 4 includes a retaining ring 41 and an insert 42, the insert 42 being disposed on one side of the retaining ring 41 and being able to be inserted into the groove.

[0074] Specifically, the outer diameter of the retaining ring 41 is larger than the outer diameter of the insert 42 to prevent the retaining ring 41 of the sealing connector 4 from being embedded in the groove.

[0075] Furthermore, the outer diameter of the retaining ring 41 is equal to the outer diameter of the opening.

[0076] Specifically, the outer diameter of the retaining ring 41 is equal to the outer diameter of the opening, which facilitates the installation of the battery and the sealing connector 4 into the battery compartment of the electronic product.

[0077] In this embodiment, the main working component of the atomizing device is the heating wire. In the entire product circuit, if the resistance is constant, the larger the current, the better the heating effect of the heating wire; that is, the larger the current, the better the atomization effect of the atomizer. If the resistance is variable, the smaller the resistance, the larger the current in the circuit, and the better the heating effect of the heating wire. The circuit between the atomizing device and the battery mainly includes the following resistances: First, the internal resistance r of the battery; Second, the resistance R1 of the circuit board 3; Third, the resistance R2 of the solder joint at the end of the wire; Fourth, the resistance R3 of the wire material; Fifth, the contact resistance R4 between the atomizing component and the heating wire; Sixth, the contact resistance R5 between the atomizing component and the battery; Seventh, the resistance of the heating wire is R6. In this embodiment, by mounting the first conductive element 31 and the second conductive element 32 on the circuit board 3, the first conductive element 31 and the second conductive element 32 serve as the positive and negative terminals of the battery, respectively. This avoids connecting the circuit board 3 to the positive and negative terminals of the battery through wires, thereby reducing the number of solder joints, i.e. reducing the number of resistors R2 and R3, and thus reducing the overall circuit resistance of the product, thereby improving the heating effect of the heating wire of the atomizing device.

[0078] The present invention also provides a battery manufacturing process for producing the battery described in any of the above embodiments. The battery manufacturing process includes the following steps: S1, fabricating a battery cell 2 and a second package, the second package including a circuit board and at least one conductive component, the conductive component being welded to the top of the circuit board 3; S2, placing the battery cell 2 inside a housing 1, and welding / pressing the negative electrode of the battery cell 2 to the bottom of the housing 1 to obtain a first semi-finished battery; S3, subjecting the first semi-finished battery to baking and electrolyte injection processes to obtain a second semi-finished battery; S4, passing the positive electrode of the battery cell 2 of the second semi-finished battery through an insulating material, and welding the circuit board 3 to the positive electrode of the battery cell 2 of the second semi-finished battery to obtain the battery.

[0079] Specifically, when cell 2 is a wound core, this battery manufacturing process is applicable. Assemblers can easily assemble cell 2 into housing 1 and weld / press the negative electrode of cell 2 to the bottom of housing 1, making housing 1 the negative electrode of the battery. The welded cell 2-housing 1 as a whole becomes the first semi-finished battery. A baking process removes moisture from the first semi-finished battery, followed by an electrolyte injection process to fill it with electrolyte. Finally, the bottom of circuit board 3 is welded to the positive electrode of cell 2, making the conductive component on circuit board 3 the positive electrode of the battery. In one embodiment, circuit board 3 includes two conductive components, one serving as the positive electrode and the other as the negative electrode. This battery manufacturing process reduces the steps of welding wires to cell 2 and circuit board 3 separately, improving battery production efficiency. The battery thus manufactured uses conductive components and housing 1 as electrodes, avoiding the connection between circuit board 3 and battery electrodes via wires, reducing the number of wires and solder joints, and achieving a reduction in resistance.
