▎ 摘　　要

NOVELTY - Anode material comprises graphene sheets, which are coated with nickel hydroxide particles and the mass proportion of the nickel hydroxide in the material is 60-95%, where the thickness of the graphene layer is 0.5-10 nm, the plane size of the graphene sheet is 500 nm to 50 mu m. The graphene sheet is tightly covered on the surface of nickel hydroxide and connected to each other to form a continuous conductive network. USE - The material is useful in nickel-base battery (claimed), various portable electronic devices, electric vehicles, and aerospace. ADVANTAGE - The material has high conductivity, not easily poisoned, has high performance rate, good cycle stability and is economical. The method has highly repetitive, simple and less time-consuming processes. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the anode material, comprising (i) uniformly dispersing the nickel base compound in water and/or organic solvent, adding graphene or graphene oxide, placing in the normal pressure reactor or hydrothermal kettle, reacting at 25-250 degrees C, where the mass ratio of the nickel base compound and graphene oxide or graphite alkene is 0.8-50:1, where the nickel-base compound acts as a precursor of nickel hydroxide, where the precursor of the nickel hydroxide is nickel nitrate, nickel sulfate, nickel chloride and/or nickel acetate, and the organic solvent is ethanol, propanol, glycol, isopropanol and/or methyl pyrrolidone, where the reaction way is hydrothermal reaction, the solvent thermal reaction and/or the precipitation reaction; and (ii) drying the product by vacuum drying, freeze-drying and/or supercritical drying to obtain solid product.
