▎ 摘 要
NOVELTY - A carbon material composite comprises a carbon material (a1) having a graphene laminated structure and a carbon material (a2) containing a fibrous carbon material, and has a volume resistivity of 1x 10-4-1x 10-3 Omega .cm. USE - Carbon material composite is used as material for forming electrode of electrical storage device (all claimed). Uses include but are not limited to portable apparatus, hybrid vehicle, electric vehicle, and domestic electrical storage apparatus. ADVANTAGE - The carbon material composite provides electrical storage device with excellent quick-charge characteristics and cycle characteristics.
