ELECTRODE FOR SECONDARY BATTERY AND METHOD FOR PRODUCING THE SAME

This secondary battery electrode is provided with a core material configured from a metal foil that softens at less than or equal to 200° C. and an electrode mixture sheet which is bonded on the surface of the core material. The electrode mixture sheet includes an active material and a fibrous binder, and the active material bites into the core material, with the maximum bite depth at least 30% of the thickness of the core material. The fibrous binder may for example have polytetrafluoroethylene as the main component.
