摘要： Novel porous and porous/nonporous 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.

摘要： Novel bipolar electrodes for electrochemical cells and methods for making same are provided. The bipolar electrodes comprise a pressure-molded composite of heat-treated graphite particles having a particle size distribution of 0 to 45 .mu.m and thermoplastic resin particles. The graphite and resin in the composite are in a weight ratio of from 1:5 to 1:1 and are formed by pressure-molding at 400 kg/cm.sup.2 or higher at 190.degree. C.
