Metal composite film and electrochemical apparatus thereof

Abstract

The present disclosure relates to the technical field of aluminum-plastic film production and discloses a metal composite film comprising an outer substrate resin layer, an intermediate metal layer and a heat-fusible resin layer; an anti-corrosion layer is formed on a side of the intermediate metal layer, the side being in contact with the heat-fusible resin layer; the anti-corrosion layer is formed of an anti-corrosion solution by coating or heat treatment; the components of the anti-corrosion solution include a trivalent chromium compound, an inorganic acid and an organic resin; the trivalent chromium compound, the inorganic acid and the organic resin are in a mass ratio of (19-60):(3-60):(6-60). The components of the anti-corrosion solution may further comprise a titanate; the trivalent chromium compound, the inorganic acid, the organic resin and the titanate are in a ratio of (19-60):(3-60):(6-60):(1-10).
