The effects of Electrolyte on the Aluminum laminate foil and the lithium ion battery corrosion

摘要

Lithium ion second battery has been grabbing an increasingly larger market share in recent years, and more lithium ion battery uses aluminum laminate foil to separate the cell from the environment. The adhesion strength of the Al layer and polypropylene layer will affect the battery quality, if the adhesion strength is so little that it should lead the battery delamiation in the process of heat sealing, and some of the aluminum laminate will corrosion in a short time and lead the battery scrap quickly.
