KOHLENSTOFF-PLASTIK-ELEKTRODENELEMENTE.

摘要

A bipolar electrode for an electrochemical cell comprises a pressure-molded composite of heat-treated graphite particles having a particle size distribution of 0 to 45 mu m and thermopalstic 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 (38) at 400 kg/cm<2> or higher at 190 DEG C. The graphite particles are heat-treated (30), screened (32), and dry-mixed (34) with the resin particles, and optionally with a binder. The mixture is screened (36) and if dry, may be compression molded (38) immediately or if wet-mixed (40) with a hydrocarbon carrier, calendered (42) into sheets which are dried (44) before compression molding (38).
