BATTERY CURRENT COLLECTOR FOIL, METHOD OF MANUFACTURING BATTERY CURRENT COLLECTOR FOIL, AND BATTERY

摘要

A method of manufacturing a battery current collector foil includes: applying wet etching (electrolytic etching) to a surface of a metal foil (aluminum foil) (step S1); and forming a conductive coating (carbon coating) on the surface of the metal foil (aluminum foil 33), which has been subjected to the wet etching, by vapor depostion (AIP) (step S2).
