NOVELTY - Lithium ion battery anode material, comprises ternary anode material and manganese iron phosphate lithium being coated with solid electrolyte by surface, where the solid electrolyte is titanium-aluminum lithium (LATP) and/or lithium lanthanum titanium oxide/lithium lanthanum titanate (LLZO). USE - The lithium ion battery anode material is useful in preparing lithium ion battery (claimed). ADVANTAGE - The lithium ion battery anode material: solves the problem that the existing lithium-ion battery has poor thermal stability and easily causes the battery to catch fire or explode. DETAILED DESCRIPTION - Lithium ion battery anode material, comprises ternary anode material and manganese iron phosphate lithium being coated with solid electrolyte by surface, where the solid electrolyte is titanium-aluminum lithium (LATP) and/or lithium lanthanum titanium oxide/lithium lanthanum titanate (LLZO); the ternary anode material is of formula (LiNixCoyMn(1-x-y)O2, x is ≥ 0.6, and y = ≤ 0.3; and the lithium manganese iron phosphate is of formula (LiMnxFe(1-x)PO4, x is 0.7-0.3. INDEPENDENT CLAIMS are included for: preparation of lithium-ion battery anode material. The method utilizes coating ions-containing solution; lithium ion battery; and preparation of lithium ion battery. The method utilizes anode conductive agent, anode binder, cathode active material, cathode conductive agent, cathode binder and electrolyte
