| description | The invention relates to a high temperature circular lithium manganate material preparation method which includes the following steps: 1) adding a metal element compound into a lithium source, and evenly mixing by ball milling in a ball mill to obtain a mixture 1; 2) adding an anionic compound into a manganese source, and evenly mixing by ball milling in a ball mill to obtain a mixture 2; (3) evenly mixing a dispersing agent, the mixture 1 and the mixture 2 by ball milling in a ball mill; and 4) burning the product of the step 3) in air atmosphere at 550-900 DEG. C for the sintering time of 6-36h. The high temperature circular lithium manganate material has high specific energy and excellent high temperature cycle charge discharge performance. The high temperature circular lithium manganate material prepared by the method has good product performance consistency, and is simple and reliable in production process, and suitable for mass production. |
