MANUFACTURING METHOD OF ELECTRODE FOR SECONDARY BATTERY

摘要

PROBLEM TO BE SOLVED: To provide an electrode for a secondary battery having both high short circuit resistance and current collecting property by making a metal-rich layer of a three-dimensional metal porous body having higher metal density than other parts to bear current collecting property and by optimizing its arrangement.

SOLUTION: The electrode for a secondary battery has an active material filled up in pores of a three-dimensional metal porous body, and a metal-rich layer of the three-dimensional metal porous body having higher metal density than other parts is arranged at parts other than a surface layer part in a thickness direction.
