ABSTRACT:
A three-dimensional substrate material for use in constructing battery electrodes comprises a sintered matrix material selected from the group consisting of reticulated metal foams, conductive fibers and metal powder compacts, and a porous covering layer of a polymeric mesh material, flexible metal screen or metal fibers, bonded to at least one surface of the matrix material to retain the sintered matrix material substantially within the planar surface of the surface of matrix material during spiral-wounding of the chemically loaded matrix material.
