A PROCESS FOR PRODUCING AN ELECTRODE SUBSTRATE

摘要

Disclosed herein are a process for producing an electrode substrate, which process comprises the steps of kneading a raw material mixture comprising from 30 to 60% by weight of short carbon fibers, from 20 to 50% by weight of a phenol resin binder and from 20 to 50% by weight of a molding additive, extruding the thus kneaded raw material mixture and after press-molding the thus extruded material by rolling or stamping, calcining the thus press-molded material in an inert atmosphere and/or under a reduced pressure and the electrode substrate produced by the above-mentioned process.
