▎ 摘　　要

NOVELTY - Sodium ion battery anode material based on titanium oxide, where the anode material has a core-shell structure, which sequentially comprises a sodium ferric sulfate core, a titanium monoxide coating layer, and a carbon coating layer from the inside to the outside. USE - The material is useful in a sodium ion battery useful as a main energy storage tool in new energy industry development. ADVANTAGE - The material: solves the problem of poor electronic conductivity of the polyanion anode material in the existing sodium ion battery; improves the defective activity of sodium ferric sulfate by using titanium monoxide to attract ferrous ions in sodium ferric sulfate; improves surface electron transfer efficiency by wrapping with carbon materials, and connection between carbon materials and sodium ferric sulfate; and enables both sodium ferric sulfate and carbon materials exhibit excellent defect-type activity based on the structural properties of titanium monoxide. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: preparing the sodium ion battery anode material based on titanium oxide; and a sodium ion battery.
