▎ 摘 要
NOVELTY - A graphene/nickel composite material preparation method involves adding graphene oxide, water, hexamethylene tetramine and nickel source, followed by mixing, heating and reacting to obtain graphene/nickel composite material, where the nickel source is a nickel source capable of ionizing nickel(II) ion in water. USE - Method for preparing graphene/nickel composite material for use as electrode material (claimed) for super capacitor. ADVANTAGE - The method enables preparing the graphene/nickel composite material with large specific surface area, better conductivity and capacity, and better effect of improving comprehensive performance of the composite material for super capacitor. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) a graphene/nickel composite material (2) an electrode material.
