NOVELTY - Preparing bamboo-leaf-shaped cobalt hudroxide/graphene composite electrode material involves mixing cobalt source, oxidized graphene, and deionized water to obtain mixed solution, and adding ethanol and dimethylformamide. The solution is transferred to a hydrothermal reactor for hydrothermal reaction. The mixture is cooled to room temperature, evacuated, and lyophilized to obtain final product. USE - Method for preparing bamboo-leaf-shaped cobalt hudroxide/graphene composite electrode material (claimed). ADVANTAGE - The method enables to prepare bamboo-leaf-shaped cobalt hudroxide/graphene composite electrode material which has good thermal stability, high crystallization degree, strong shape controllability is strong, and has perfect energy material.
