▎ 摘  要

NOVELTY - A graphene based super capacitor electrode pole comprises an electrode current collector layer and an active material layer. The electrode current collector layer is laminated graphene, and active material layer is porous graphene. USE - Graphene based super capacitor electrode pole (claimed). ADVANTAGE - The capacitor electrode pole active material layer is tightly contacted with electrode current collector layer, and effectively reduces the interface resistance and battery internal resistance, with strong electrolyte absorbing and storing capacity, increases high-rate discharge circuit performance and energy density of capacitor. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of electrode pole, which involves (1) dispersing exfoliated graphene and carbon nanotubes and/or carbon fibers in water to obtain laminated graphene slurry with solid content 1-10 wt.%, (2) dispersing graphene and pore forming agent in water in mass ratio 1:(1-5), adding carbon nanotubes and/or carbon fibers to form slurry of porous graphene with solid content 1-10 wt.%, (3) brushing the slurries obtained in steps (1) and (2) successively on a substrate, heating at 400-1200 degrees C under inert atmosphere for 0.5-12 hours, pickling, water washing and drying.
