The invention discloses preparation methods of antimony trioxide and an antimony trioxide composite material and applications of the antimony trioxide and the antimony trioxide composite material in sodium-ion batteries. The antimony trioxide and the antimony trioxide composite material are used as sodium-ion battery negative electrode materials. The antimony trioxide composite material is prepared from the antimony trioxide, metal or metallic oxides by using a complex method, wherein the metal comprises Ag, Au, Cu, Fe, Sn, Si and Ni, the metallic oxides comprise nickel oxide, copper oxide, tin oxide, cobalt oxide, iron oxide and manganese oxide, and the mass percentage of the antimony trioxide is 50-99%. The antimony trioxide and the antimony trioxide composite material which are prepared by using multiple effective methods are used as the sodium-ion battery negative electrode materials, have the advantages of high specific capacity and good cycling stability, and simultaneously are low in manufacturing cost and suitable for large-scale development and application of the sodium-ion batteries. |
