NOVELTY - Composite coated all-solid-state battery anode material comprises anode material and composite coating layer coated on the surface of the anode material. The composite coating layer is a composite coating containing lithium metal oxide and conductive material. USE - The composite coated anode material is used for all-solid-state battery (claimed). ADVANTAGE - The anode material has double characteristics of lithium ion conduction and electronic conduction, constructing the electrode inner body phase ion and electronic path, improving the multiplying power performance and circulating performance of the battery, and accelerating the large-scale application process of the all-solid-state battery. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) preparation of the anode material comprising dry mixing or wet mixing to prepare precursor powder, and calcining; (2) all-solid-state battery comprising anode, cathode and solid electrolyte, where the anode comprises the anode material; and (3) preparation of the all-solid-state battery comprising the grinding ceramic solid electrolyte powder, adding into dispersion, coating on the membrane, and obtaining functional membrane; taking the anode material as anode; taking the metal lithium as cathode; taking the functional ion film as the middle film; injecting the methyl acrylate as the polymer monomer; assembling the lithium ion battery; heating; standing and solidifying; and obtaining the all-solid-state battery taking the polymethyl acrylate and ceramic solid electrolyte as the composite solid electrolyte.
