METHOD FOR MANUFACTURING ELECTRODE AND METHOD FOR MANUFACTURING SECONDARY BATTERY

摘要

Disclosed is a method for manufacturing a positive electrode including a positive electrode substrate made of aluminum foil and a positive electrode active material layer containing a positive electrode active material on the positive electrode substrate. This method includes the steps of forming the positive electrode active material layer on the positive electrode substrate; forming a protective layer on the positive electrode substrate; stretching an exposed region of the positive electrode substrate after the steps of forming the active material layer and the protective layer; and compressing the positive electrode active material layer after the stretching step.

1. A method for manufacturing an electrode comprising a substrate and an active material layer containing an active material on the substrate, the method comprising the steps of:
forming the active material layer on the substrate; forming a protective layer on the substrate along an edge of the active material layer; stretching a region of the substrate where the active material layer is not formed after the steps of forming the active material layer and the protective layer; and compressing the active material layer after the stretching step.
