METHOD OF MANUFACTURING ELECTRODE FOR LITHIUM SECONDARY BATTERY, AND LITHIUM SECONDARY BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a method of manufacturing an electrode for a lithium secondary battery in which superior charge and discharge cycle characteristics and higher volume energy density are realized in the manufacturing method of the electrode for the lithium secondary battery fabricated by film molding a thin film of an active material to store/release lithium on a current collector by using a film molding drum having a curvature.

SOLUTION: A device shown in Fig. 1 is used, the curvature of the direction opposite to the film molding time is provided in the electrode in the temperature atmosphere of 100°C or more and 400°C or less after film molding, and a stress relaxation treatment is applied to the electrode.
