Lithium ion battery cathode material and preparation method thereof |
| abstract |
The invention discloses a TiO 2 2 Hollow mesoporous spherical shell coated TiO 2 A nano-particle lithium ion battery cathode material and a preparation method thereof belong to the technical field of lithium ion batteries. The preparation method is to use the classical stober method to prepare the titanium dioxide 2 The surface of the nano particle P25 is coated with a layer of SiO 2 Then adopting isopropyl titanate hydrolysis method to prepare SiO 2 Coating a layer of TiO on the surface 2 Removal of SiO 2 Obtaining TiO after layering 2 Hollow mesoporous spherical shell coated TiO 2 A nanoparticle material. The TiO provided by the invention is adopted 2 Hollow mesoporous spherical shell coated TiO 2 The nano particles are used as the negative electrode material of the lithium ion battery, and show good charge and discharge performance and cycle stability. The method has the advantages of simple synthesis process, mild reaction conditions and low cost, and is suitable for large-scale synthesis. |
