NOVELTY - Performing metal foil treatment process involves carrying out plasma treatment on the surface of the metal foil, collecting above-mentioned plasma-treated metal foil into a roll, and baking the roll-shaped metal foil, then cooling the roll-shaped metal foil. USE - Method for performing metal foil treatment process for an electrode pole piece of an electrochemical device (all claimed). ADVANTAGE - The process can remove the peculiar smell caused by the plasma processing. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for an electrode pole piece, comprising an active material layer, the active material layer including an active material, a binder, and a conductive agent.
