After the single cell is assembled, it is sealed with aluminum plastic film to form a battery. The aluminum plastic film plays the role of protecting the contents. Aluminum plastic composite film for soft pack lithium battery has good barrier property, electrolyte stability, cold stamping formability, puncture resistance and insulation. It is the most critical safety link in soft package lithium battery and a composite material with extremely strict technical requirements.
