METHOD FOR MANUFACTURING ELECTRODE FOR LITHIUM SECONDARY BATTERY AND ELECTRODE FOR LITHIUM SECONDARY BATTERY MANUFACTURED BY USING SAME

Document Type and Number:

WIPO Patent Application WO/2020/085726

Kind Code:

A1

Abstract:

The present invention provides a method for manufacturing an electrode for a lithium secondary battery, the method comprising the steps of: forming a first electrolyte membrane by impregnating an electrode current collector with a composition for forming the first electrolyte membrane and then applying current thereto; and forming a second electrolyte membrane by impregnating, with a second composition, the electrode current collector with the first electrolyte membrane thereon and then applying current thereto, wherein, among the composition for forming the first electrolyte membrane and the composition for forming the second electrolyte membrane, one is a composition for forming an organic electrolyte membrane, the other composition is a composition for forming an inorganic electrolyte membrane, and the composition for forming an inorganic electrolyte membrane comprises a compound represented by chemical formula 1.
