MANUFACTURING METHOD OF ELECTRODE FOR LITHIUM SECONDARY BATTERY

摘要

PROBLEM TO BE SOLVED: To manufacture an electrode for a lithium secondary battery with favorable adhesion between a collector and an active material film in an electrode for a lithium secondary battery with a lithium occluding and discharging active material film accumulated and formed on a metallic foil used as a collector. SOLUTION: This manufacturing method is characterized by that a surface of the metallic foil is roughened by spraying and impacting particulates on the surface of the metallic foil and the active material film is accumulated on the roughened surface.
