| titleOfInvention | A kind of tin-iron-carbon composite negative electrode material for sodium ion battery and preparation method thereof |
| abstract | The invention relates to a tin-iron-carbon composite negative electrode material for sodium ion batteries and a preparation method thereof. The negative electrode material has at least one of the following features: (1) the negative electrode material is a ball with an egg yolk structure and a size of 300-1500 nm; (2) the negative electrode material comprises an iron-tin alloy coating layer with a thickness of 2-20 nm; ( 3) in this negative electrode material, the mass percent of iron is 0.6-50%; (4) in this negative electrode material, the mass percent of tin is 10-95%; (5) in this negative electrode material, the mass percent of carbon is 5- 60%, and a carbon layer of 10-50 nm thickness is formed. The preparation method includes the following steps: preparation of hollow SnO2 nanospheres; preparation of SnO2 @ Fe2O3 ; preparation of SnO2 @ Fe2O3 @RF ; preparation of Sn/ FeSn2 @C to obtain tin for sodium -ion battery ‑Iron‑carbon composite anode material. Compared with the prior art, the invention has high first coulombic efficiency and excellent cycle stability, and solves the technical problems of poor cycle stability and low first coulombic efficiency of the Sn anode material of sodium ion batteries. |
