The plastic sealing layer 4 can also provide the waterproof and dustproof performance of the battery. Referring to Figures 5 and 6, the outer surface of the nickel ring 1 is exposed outside the plastic sealing layer 4 to facilitate connection with the battery tabs 10, thereby improving the safety of the battery. performance, stability and service life.

In step S500, the hard board 2 is cut from the substrate 8, mounted on the soft board 5, and then the soft board 5 is divided. When making the battery protection plate, the finished hard plate 2 is cut from the base plate 8 . In this way, each independent battery protection board can be separated to facilitate subsequent processing and installation. The soft board 5 is usually a flexible base material, which can provide greater flexibility and bendability. After the hard board 2 is mounted, The soft board 5 is segmented to separate each battery protection board, so that an independent battery protection board can be obtained to facilitate subsequent installation and use.

As shown in Figures 7 to 13, in a preferred embodiment, a battery packaging method includes the method for making a battery protection plate with a nickel ring according to any one of the above embodiments, and also includes a battery body 11 and tabs. 10. The pole lug 10 is connected to the battery body 11. The manufacturing method of the battery protection board includes the design of the plastic sealing layer 4, the connector 9, etc., which can provide protective functions for the battery, such as physical protection, dustproof and moistureproof, etc., and extend the service life of the battery.

As shown in Figures 7 and 8, in some embodiments, a battery packaging method includes the following steps:

In step S1, the tab 10 and the nickel ring 1 are welded and connected. Weld and connect the tab 10 to the nickel ring 1, so that the current transmission and communication functions between the battery protection plate and the battery body 11 can be realized. The welding method between the tab 10 and the nickel ring 1 can be CW continuous welding. CW The advantages of continuous welding are: it can achieve high-speed and high-quality welding, improve production efficiency and product reliability; CW continuous welding can achieve high-precision solder joint control, avoiding defects caused by overheating or insufficient heat; CW continuous welding can achieve different Welding between materials, such as aluminum and nickel; CW continuous welding can handle thicker tabs 10 and nickel ring 1, as long as the appropriate laser power and parameters are selected.

Referring to Figures 10 and 11, in a conventional battery protection board, the electronic device 3 is on one side of the hard board 2, the plastic layer 4 wraps the electronic device 3, and the other side of the hard board 2 is mounted on the soft board 5. The soft board 5 An L-shaped nickel piece 13 is mounted on the top. In this solution, the nickel piece ring 1 is welded to the tab 10. The nickel piece ring 1 does not occupy the thickness space of the protective plate. The thickness of the stack is only the thickness of a single layer of tab 10 and the plastic sealing layer. 4 height, 2 thickness of hard board and 5 thickness of soft board. In the conventional scheme, after the L-shaped nickel sheet 13 and the tab 10 are welded, the stacking thickness is a single layer of tab 10 thickness, a double-layer L-shaped nickel sheet 13 thickness, and a plastic sealing layer 4 height, 2 thickness of hard board and 5 thickness of soft board. Compared with the conventional solution, this solution reduces the thickness of two layers of L-shaped nickel sheets 13.

Through this arrangement, the battery protection plate and the battery body can be ensured. 11. Stable connection and tight combination.

Taking this solution as an example, if the thickness of the battery body 11 is 2.7 mm and the battery back step is 0.9 mm, the battery protection plate can only be placed in the 1.8mm space within the groove 12. After removing the insulating tape, double-sided tape and other materials, only about The thickness space of 1.5 mm, if the PCB hard board 2 is selected to be 0.6 mm, the device height is required to be lower than 0.6 mm, and the soft board 5 is selected to be 0.25 mm, the thickness of the conventional soft pack battery head is the thickness of the battery protection plate, the thickness of the pole lug 10, the thickness of the double layer solder joint thickness and step height. The head thickness of a soft-pack battery is the sum of the thickness of the battery protection plate, the thickness of the tab 10, the single-layer solder joint thickness and the step height. Compared with the conventional soft-pack battery, one layer of welding is reduced. point thickness, and at the same time, because the thickness of the battery protection plate reduces the thickness of two layers of L-shaped nickel sheets 13, the overall thickness of the two layers of L-shaped nickel sheets 13 and one layer of solder joints is reduced, and the gain in the thickness direction is about 0.3mm, making the soft pack battery Suitable for ultra-thin mobile phone batteries and other fields.

Step S3 , bend the flexible plate 5 so that the width of the bent flexible plate 5 is smaller than the width of the battery body 11 . Referring to Figures 12 and 13, by bending the flexible plate 5 so that the width of the flexible plate 5 is smaller than the width of the battery body 11, the overall size of the battery assembly can be reduced while maintaining the stability of the connection, which is helpful. Achieve higher density battery assembly, improve the compactness and space efficiency of the battery system, and at the same time, it will not affect the connection between the connector 9 at the end of the flexible board 5 and the external circuit, and improve the stability and reliability of the battery assembly.

Step S4: Use insulating tape auxiliary materials and fireproof foam auxiliary materials for packaging. After the battery protection plate is located in the groove 12 of the battery body 11, the battery is packaged using insulating tape auxiliary materials and fireproof foam auxiliary materials. The insulating tape can provide insulation effect between the battery protection plate and the battery body 11 to reduce the risk of battery short circuit. Fireproof foam has flame retardant and heat insulation functions to improve battery safety.

Step S5: Perform performance test and fire test on the battery. Performance testing can evaluate various key parameters of the battery, such as battery capacity, voltage characteristics, discharge and charging efficiency, etc. Through testing, it can be determined whether the performance indicators of the battery meet the design requirements and verify the reliability and reliability of the battery in actual use. Stability and fire resistance testing are important links in evaluating the safety of batteries. The flame retardant performance and thermal stability of the battery can be evaluated through fire testing to ensure that the battery will not cause fire or generate dangerous heat under abnormal conditions.
