▎ 摘　　要

NOVELTY - Composite electroconductive particles are obtained by coating conductive core particles having average primary particle size of 15-500 mu m, with graphene. USE - Composite electroconductive particles are used in conductive resin (claimed), battery electrodes, energy storage material and electronic device. ADVANTAGE - The composite electroconductive particles have low interfacial resistance and provides excellent electroconductive improvement effect in resin. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of composite electroconductive particles, which involves coating electroconductive core particles with graphene oxide and reducing the graphene oxide.
