| 摘要 |
The present invention relates to the technical field of preparation of lithium-ion battery electrode materials. Disclosed specifically is a preparation method for a doped lithium titanate negative electrode material. In the method of the present invention, a lithium source, nano-silica, and glucose are added into a ball mill according to a certain material ratio, spray dried when ball milled with anhydrous ethanol serving as a medium, then sintered in an inert atmosphere condition, and then ball milled and sieved to complete the process. The material exhibits great electrochemical properties being used as a lithium-ion battery negative electrode material. The present invention has a simple preparation process and the negative electrode material prepared has a high reversible capacity, high-rate cycling performance, and great rate charging and discharging performance. |
