After the cells are assembled, the whole battery pack needs to be fixed with insulating sheets. The reason why the epoxy sheet is selected as the outer casing of the battery pack instead of steel or aluminum one is that although these materials are beautiful and sturdy, it is hard to guarantee the well combination of the battery cells. If handed improperly, the battery cells might probably be scratched, which will cause battery leakage and safety accidents. Therefore, the epoxy sheet is very ideal for li-ion battery insulation and packaging.
