Abstract: |
A process for preparing spherical V2O5 and lithium vanadate used as positive electrode material of Li-ion battery includes smelting NH4VO3, quick cooling in deionized water to generate V2O5 sol, spray drying to obtain spherical V2O5, adding LiOH to V2O5 sol, doping with CO, Ni, or Al, spray drying and heat treating to obtain spherical doped Li1+xV3O8. Its advantages are high stack density, high specific capacity and improved electrochemical performance. |
