The critical performance requirements of lithium batteries for aluminum-plastic film products

by：Vglory 2021-03-27

The important performance requirements of lithium batteries for aluminum-plastic film products (1) The electrolyte in the lithium battery is composed of a variety of organic solvents and lithium salts that can quickly appear highly corrosive hydrofluoric acid when exposed to moisture; (2) aluminum-plastic film inner film It must be resistant to the puncture of the burrs around the battery cells, and must have insulation under high temperature and pressure conditions; (3) Lithium batteries cannot exist out of the package, and the service life of the aluminum-plastic film is the same as the product's inventory and service life. Therefore, lithium batteries have higher requirements for the service life of the aluminum plastic film; (4) The use process of lithium batteries is a dynamic electrochemical reaction process, and the aluminum plastic film must effectively resist the swelling, dissolution, and dissolution of the internal electrolyte. Permeation, absorption and electrochemical reaction. The aluminum plastic film of lithium battery can protect the lithium battery after the monolithic lithium battery is encapsulated. Nowadays, with the continuous progress and development of packaging technology, a variety of flexible packaging products are widely used in all walks of life, and lithium battery assembly is no exception. To a large extent, flexible plastic packaging has the advantages of traditional packaging incomparable. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
