Embodiment Construction
[0007] Below by embodiment the present invention will be further described.
[0008] Take a certain amount of Li 2 CO 3 and electrolytic MnO 2 , after adding doping raw materials, through mechanical mixing, ball milling, and passing through a 400-mesh sieve, the under-sieve is the mixture, and the mixture is roasted in a rotary electric furnace, and at the same time, it is -1 The compressed air is fed into the furnace at a constant flow rate, and the calcined multi-element doped lithium manganese oxide is cooled with the furnace, and then ball milled and multi-stage sieved to obtain the final product.
[0009] Select each relevant parameter in the above-mentioned technology, form embodiment 1, 2, 3, list is as follows, in the table " % " is that each component accounts for the mass percent of compound total amount:
[0010] Example 1
[0011] Note: The impurity content of other metal ions is allowed to be less than 0.05% in the composition of the mixture.
