Analysis of lithium battery cell production matters

Since the battery cell is a soft package, in order to ensure that the performance of the battery core is not damaged, the battery core must be handled carefully. The lithium battery cell includes a cell body composed of a positive electrode plate, a negative electrode plate and a diaphragm plate, and the tail end of the diaphragm plate is fixed and bonded to the cell body by an adhesive. The use of adhesive to fix the end of the diaphragm on the body of the battery can serve the following purposes: one is to reduce the thickness of the battery to further realize the thinness of the battery; the other is to beware of the wrinkle problem that may be caused by the use of adhesive tape to close the battery. Improve the appearance of the battery and effectively reduce the repair rate; third, the cost of the adhesive is lower than that of the adhesive tape, which can effectively reduce the production cost of the lithium battery. When the lithium battery cell is processed and manufactured, it is particularly important to dry the surrounding air humidity. The main reasons are: guard against unnecessary chemical reactions such as fires and explosions; guard against product quality problems; master and control and dry A lot of air-related costs. When processing lithium battery cells, the surrounding water vapor is very sensitive. You must pay attention to this point. This challenging processing environment should be equipped with a reliable performance. At the same time, it should be aware of the surrounding environment. Some objects containing water vapor may be initially selected for water vapor detection. Lithium batteries should not have liquid from the electrolyte, but once the electrolyte leaks and touches the exposed circuit, the high-potential terminal material may dissolve and then precipitate to the low-potential terminal, which may cause a short circuit. The design of the protection board must include an overturn protection layer. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
