▎ 摘　　要

NOVELTY - Preparing aluminum composite current collector comprises providing copper foil and polymer material film with aluminum metal layer on the surface, bonding the two sides of the polymer material film to the aluminum metal layer on the surface of the copper foil respectively, peeling off the copper foil after hot pressing, where the pressure of the hot pressing is 500kg-1000 kg, the temperature is 40-60℃, and the pressing speed is 30-50 m/minute. USE - The current collector is useful in anode, battery and power utilization device (all claimed). ADVANTAGE - The current collector has high tensile strength and elongation, which is conducive to improving the extrusion resistance and impact resistance of the battery. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: Aluminum composite current collector prepared by the above method; Anode; Battery; and Power utilization device. DESCRIPTION OF DRAWING(S) - The drawing shows a structure schematic diagram of the aluminum composite current collector. 100Polymer material film 200Aluminum metal layer 300Agglomerant
