Abstract
A battery electrode comprises a plaque made of a sponge-like porous metal matrix having a multiplicity of cells connected with each other three-dimensionally, wherein the sectional area of the gratings making up the sponge-like metal porous plaque decreases continuously along the thickness of the plaque from the surface toward the central part and an active material is impregnated in the porous plaque.
