▎ 摘　　要

NOVELTY - Graphene structure carbon electrode material preparation involves soaking and drying dried shell biomass in a nickel salt solution, and then subjecting the dried shell biomass to carbonization in an inert atmosphere at 650-750 degrees C. The carbonized shell biomass is dipped into an acid aqueous solution and then filtered to get the carbonized product. The carbonized product is immersed in an alkali aqueous solution, dried in an inert atmosphere at 650-750 degrees C, and then cooled and washed to neutral to obtain the graphene-structure carbon electrode material. USE - Method for preparing graphene structure carbon electrode material used as capacitor (claimed). ADVANTAGE - The method prepares the graphene structure carbon electrode material in a simple and cost-effective manner with excellent performance on large-scale. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the transmission electron microscopic image of the graphene structure carbon electrode material.
