▎ 摘  要

NOVELTY - Preparation of three-dimensional wood graphene material by super capacitor electrode method comprises cutting wood into thin sheet with the same size, dispersing wood sheet into hexahydrate nickel nitrate alcohol solution to obtain wood-nickel composite material, reacting wood-nickel composite material under inert atmosphere to obtain precursor of nickel coating, adding obtained precursor into tubular furnace, pumping atmosphere into tubular furnace of vacuum, heating at 1200 degrees C, subsequent furnace cooling, concentrating obtained product with concentrated nitric acid and heating to remove nickel. USE - Method for preparing three-dimensional wood graphene material by super capacitor electrode method. ADVANTAGE - The method can obtain product with fast channel ion and electron conduction, abundant micro-pores, increased specific surface area and capacitance of electrode.
