METHOD FOR MANUFACTURING ELECTRODE OF LITHIUM SECONDARY BATTERY

摘要

PROBLEM TO BE SOLVED: To manufacture an electrode of a lithium secondary battery which is high in a discharging capacity and excellent in a property of a charging and discharging cycle. SOLUTION: The method for manufacturing the electrode of the lithium secondary battery deposits and forms an active material film, which occludes and discharges lithium, on a metal film used as a collector. A surface of the metal film is roughened by a wet-etching process. The active material film is deposited on the roughened surface.
