Negative Electrode Material

Pr doped SnO2 particles as negative electrode material of lithium-ion battery are synthesized by the coprecipitation method with SnCl4·5H2O and Pr2O3 as raw materials. The structure of the SnO2 particles and Pr doped SnO2 particles are investigated respectively by XRD analysis. Doping is achieved well by coprecipitation method and is recognized as replacement doping or caulking doping. Electrochemical properties of the SnO2 particles and Pr doped SnO2 particles are tested by charge-discharge and cycle voltammogram experimentation, respectively. The initial specific discharge capacity of Pr doped SnO2 the negative electrode materials is 676.3mAh/g. After 20 cycles, the capacity retention ratio is 90.5%. The reversible capacity of Pr doped SnO2 negative electrode material higher than the reversible capacity of SnO2 negative electrode material. Pr doped SnO2 particles has good lithiumion intercalation/deintercalation performance.

Negative Electrode Material

Sn dopants undergo restructuring into Ti sites of TiO2 upon lithiation reaction. These Sn dopants attract Li to form local SnLix alloys, which sufficiently increase the capacity of Sn-substituted TiO2 as a negative electrode material.
