Aluminum plastic film packaging material for use in lithium battery to prolong service life

摘要

An aluminum plastic film packaging material for lithium batteries to prolong service life, at least comprising an inner layer and an aluminum foil layer, is performed an anti-corrosion treatment between the inner layer and the aluminum foil layer by one of the following ways:1) a chromium-containing anti-corrosion layer is formed from an aqueous modified resin containing trivalent chromium; and2) an adhesive layer with non-chromium material is formed from an aqueous modified resin, an epoxy curing agent, a silane coupling agent and a nano-sized metal oxide particle.
