▎ 摘　　要

NOVELTY - Modified composite current collector, comprises a modified layer and a metal layer sequentially laminated on the surface of the polymer film. The modified layer is formed by chemical vapor deposition of polyethylene glycol substances on the surface of the polymer film. USE - The modified composite current collector is useful in a battery of an electric device (all claimed). ADVANTAGE - The modified composite current collector can keep the surface tension stable for a long time. The polymer layer and the metal layer are tightly bonded by the modified layer, so that the modified current collector structure is stable, and the bonding force is strong. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing modified composite current collector.
