ELECTRODE FOR ELECTROCHEMICAL ELEMENT AND ELECTROCHEMICAL ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide an electrode for electrochemical element capable of joining a collector and an electrode lead with high weld strength.SOLUTION: The electrode for electrochemical element includes: an electrode main body 1 which has a collector 1a formed with an active material layer 1b over a principal plane; an electrode lead 2 which is disposed on a principal plane of the electrode main body 1; and a fusion part 3 which is formed by fusing an end face of the electrode main body 1 and an end face of the electrode lead 2. The fusion part 3 is formed so that the dimension thereof in a thickness direction of the electrode main body 1 is larger than the sum of thickness of the electrode main body 1 and the electrode lead 2.
