▎ 摘　　要

NOVELTY - Preparing foam graphene-loaded nickel-cobalt-oxygen anode material, involves treating nickel foam and immersing it in graphene oxide solution and coating foam in solution. The graphene oxide on nickel is chemically reduced with reducing agent. The foamed nickel coated with graphene is placed in a solution, and etched by acid, and corresponding cobalt salt in molar amount of 1:2. The solution is transferred to a 100 milliliter hydrothermal reaction kettle and reacted at 160-180 degrees C for 3-5 hours, after temperature is reduced to room temperature. USE - Preparing foam graphene-loaded nickel-cobalt-oxygen anode material in lithium ion battery (claimed). ADVANTAGE - The method enables to prepare foam graphene-loaded nickel-cobalt-oxygen anode material which has large specific surface area and improves electrochemical performance of material. It's preparation process is simple and easy to operate. DETAILED DESCRIPTION - Preparing foam graphene-loaded nickel-cobalt-oxygen anode material involves treating nickel foam and immersing it in graphene oxide solution and coating foam in solution. The graphene oxide on nickel is chemically reduced with reducing agent. The foamed nickel coated with graphene is placed in a solution, and etched by acid, and corresponding cobalt salt in molar amount of 1:2. The solution is transferred to a 100 milliliter hydrothermal reaction kettle and reacted at 160-180 degrees C for 3-5 hours, after temperature is reduced to room temperature. The precipitate is vacuum-filtered and washed multiple times with ethanol. The vacuum oven is dried at 60-80 degrees C for 10-15 hours. The precipitate is calcined at 500-600 degrees C for 3-5 hours to obtain foam graphene loaded with nickel-cobalt-oxygen.
