Problems solved by technology

[0002] Aiming at the problem that lithium batteries in hard boxes are easy to release gas during use, and the pressure increases to cause explosions, a new type of flexible packaging material-aluminum-plastic film has begun to appear on the market. In the case of hidden dangers, the soft-pack lithium battery will only blow up and crack at most, instead of exploding like steel-cased and aluminum-cased cells
The existing aluminum-plastic film has poor puncture resistance

Abstract

The invention discloses an aluminum-plastic film for puncture-resistant lithium battery packaging, which comprises: an outer film layer, a puncture-resistant layer, an inner film layer, an aluminum foil layer and a heat-sealing layer arranged sequentially from outside to inside, the outer film layer, the anti-puncture The puncture layer, the inner film layer, the aluminum foil layer and the heat-sealing layer are bonded and compounded by glue, the outer film layer is a polyfluoroethylene propylene film, the inner film layer is a polyester film, and the puncture-resistant layer is made of The warp and weft are interwoven, the warp is aramid yarn, and the weft is nylon yarn. Through the above method, the structure of the present invention is simple and reasonable, and has better puncture resistance performance.

Description

technical field [0001] The invention relates to the technical field of packaging materials, in particular to an aluminum-plastic film for puncture-resistant lithium battery packaging. Background technique [0002] Aiming at the problem that lithium batteries in hard boxes are easy to release gas during use, and the pressure increases cause explosion problems, a new type of flexible packaging material-aluminum-plastic film has appeared on the market. In the case of hidden dangers, the soft-pack lithium battery will only blow up and crack at most, instead of exploding like steel-cased and aluminum-cased cells. The existing aluminum-plastic film has poor puncture resistance. SUMMARY OF THE INVENTION [0003] The technical problem mainly solved by the present invention is to provide an aluminum-plastic film for puncture-resistant lithium battery packaging, which has a simple and reasonable structure and has better puncture-resistant performance. [0004] In order to solve th...
