| titleOfInvention | Preparation method of composite coated lithium titanate negative electrode material |
| abstract | The invention discloses a preparation method of a compound coated lithium titanate negative electrode material, wherein the compound coated lithium titanate negative electrode material is Zn 2 Te 3 O 8 ·xTiTe 3 O 8 (wherein x is 0-1), and the preparation method comprises the following steps: preparing pure-phase lithium titanate precursor by adopting a sol-gel method, and mixing the precursor with Zn in a certain proportion 2 Te 3 O 8 ·xTiTe 3 O 8 The mixture is subjected to solid phase grinding and is calcined in air atmosphere to obtain the Zn 2 Te 3 O 8 ·xTiTe 3 O 8 The lithium titanate negative electrode material coated with the composite, wherein Zn is contained in the negative electrode material 2 Te 3 O 8 ·xTiTe 3 O 8 The coating is uniformly coated on the surface of lithium titanate, inhibits the growth of lithium titanate particles, reduces the pH value of the material, and contains Zn 2 Te 3 O 8 ·xTiTe 3 O 8 The chemical stability of the surface coating layer of the material is good, the structure stability of lithium titanate is effectively kept in the repeated charging and discharging process, and the multiplying power and the cycle performance of the lithium titanate are improved; meanwhile, the whole preparation process is simple, easy to test and wide in application prospect. |
