Soft pack batterysingle energy density in the common three forms of lithium battery package, the easiest to do high, but to the module design this layer, the overall safety of the product is the heaviest task to consider, it can be said that part of the cell live transferred to the module structure.
The significance and purpose of soft pack lithium-ion battery packaging are to completely isolate the inside of the cell from the outside using a high barrier flexible packaging material, leaving the inside in a vacuum, oxygen-free and water-free environment.
Designing soft-pack batteries isn’t easy. Here are some of the main challenges: Since the pouch is soft and thin, it doesn’t offer much physical protection. Any sharp object or pressure can damage the battery. The external battery housing or module design must take on this role. The heat sealing process must be perfect.
The physical structure of the soft pack cell determines that it isnot easy to explode, generally only the shell can withstand high enough pressure, it is possible to blow, and the internal pressure of the soft pack cell is a large, it will start from the edge of the aluminum-plastic film pressure relief, leakage.
It’s a packaging method where battery cells are enclosed in a flexible aluminum-plastic pouch instead of a hard metal case. This design is lighter and more flexible than traditional formats. Why is heat sealing in pouch cells so critical?
Lithium battery module consists of lithium titanate battery, module mounting plate, insulating isolation block, cover case, long connection row, short connection row, pole column, and the structure of lithium battery module is shown in the following figure.
