ABSTRACT:
Novel porous and porous
onporous composites useful as electrodes in electrochemical cells and methods for making same are provided. The porous composites comprise a pressure-molded composite of carbon particles and thermoplastic resin particles which have a particle size distribution of 0 to 45 .mu.m. The pores are formed by dry mixing a water-leachable salt with a pore size distribution of 5 to 200 .mu.m with the carbon and resin mixture and water extracting the salt to form the porous composite.
