▎ 摘　　要

NOVELTY - A foam nickel composite material preparing method involves preparing methyl alcohol solution with oxidation graphene and surfactant by using an ultrasonic device. An oxidation graphene suspension solution is obtained. A uniform suspension is formed in a hydrothermal kettle and a solvent heat reaction is processed at a temperature of 100-200 degrees C. A nickel cobalt hydroxide is generated on surface of foam nickel. A surface cover graphene and a nickel-cobalt series hydrotalcite layer i.e. foam nickel composite material is formed. USE - Method for preparing a foam nickel composite material (claimed). ADVANTAGE - The method enables obtaining the foam nickel composite material in a simple and economical manner with high ratio capacity and high stability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a foam nickel composite material.
