| titleOfInvention | Lithium vanadate anode material and preparation method thereof |
| abstract | The invention discloses a lithium vanadate anode material which consists of nanosphere-shaped lithium vanadate particles with hollow core-shell structures, wherein nano holes are distributed in the core-shell layer. The preparation method comprises the following steps: dissolving a compound containing tetravalent vanadium in a reducing solvent, stirring until the solution is clarified, transferring the obtained clarified liquor into a sealed reaction kettle for carrying out a reduction reaction, cooling the liquor to room temperature after the reduction reaction is finished so as to obtain a nano V2O3 precipitate with a hollow structure; dissolving the obtained nano V2O3 precipitate and a lithium source compound in an organic solvent for sharply stirring, drying the products obtained in the reaction, and sintering the products to obtain the particles. The positive active material of the prepared lithium vanadium oxide has a hollow structure, is small in particle size, high in dispersing property, high in electric capacity and high in stability and has high cycle performance and high rate performance; and moreover, in the whole process, the synthesis temperature is low, the energy loss is low, the operation is easy and large-scale production can be performed. |
