ABSTRACT:
A carbon cathode structure is described comprising an aggregate of discrete, porous, semi-rigid carbon conglomerates which are impressed from both sides onto a screen-like substrate for physical support thereby. The substrate additionally functions as a current collector by uniformly and electrically contacting the interior of the resulting structure. Electrolyte-conducting channels formed between adjacent conglomerates of the thick, porous cathode structure serve to maximize the cell rate capability and cell discharge capacity.
