| titleOfInvention | Composite electrode material and preparation method and application thereof |
| abstract | The invention discloses a composite electrode material and a preparation method and application thereof, wherein the composite electrode material comprises the following components: tin dioxide and phosphorus, the phosphorus and the tin generated by the tin dioxide conversion reaction produce combination. The composite electrode material provided by the invention takes tin dioxide as a main raw material, phosphorus is added into the tin dioxide to be compounded into the electrode material, the phosphorus is added to be combined with tin generated by the conversion reaction of the tin dioxide, and SnP and Li are used x The SnP alloy is used for releasing lithium, so that the reaction path of the tin dioxide for releasing lithium is changed, the charging voltage platform of the tin dioxide is reduced, and the cycling stability of the material is improved. The capacity retention rate of the tin dioxide-phosphorus composite electrode material provided by the invention is 80-90% after 100-200 cycles, and compared with a pure tin dioxide electrode material, the charging voltage platform is reduced by about 0.5V, the first coulombic efficiency is improved by 15-19%, so that the charging voltage of the composite electrode material can be effectively regulated and controlled by adding phosphorus, and the first coulombic efficiency is obviously improved. |
