ABSTRACT:
A current collector in the form of a conductive substrate subjected to a special chemical etch on both major surfaces to provide a "basket weave" structure, is described. The basket weave structures has a lattice construction surrounded by a frame and comprising first strand structures intersecting second strand structures to provide a plurality of diamond-shaped openings or interstices bordered by the strands. The strand structures intersect or join with each other at junctions thereby forming the current collector as an integral unit.
