| 摘要 |
A rechargeable battery electrode of the present invention is produced by filling voids in a three-dimensional metal porous body (1) with an active material (2). A metal-rich layer (3) having a metal density greater than other portions is provided in a region except for thicknesswise surface layer portions of the three-dimensional metal porous body. The metal-rich layer is allowed to be responsible for current collecting characteristics, and the configuration thereof is optimized. In this manner, a rechargeable battery electrode excellent in both short circuit resistance and current collecting characteristics is achieved.
