| titleOfInvention | Preparation method of lithium manganate |
| abstract | The invention discloses a preparation method of lithium manganate. Mixing LiMnO 4 Uniformly mixing manganese powder, nano niobium pentoxide, nano aluminum oxide and boron trioxide, and performing ball milling to obtain a mixture; introducing nitrogen into the mixture in a rotary kiln for calcination, and then cooling to a temperature lower than 100 ℃; crushing the cooled material by air flowThen carrying out electromagnetic deferrization for 3-4 times, sieving the mixture by a 200-mesh sieve and a 250-mesh sieve, and then carrying out vacuum packaging to obtain the product. The preparation method disclosed by the invention is simple in preparation process, high in production efficiency and low in cost, and the obtained lithium manganate is low in lithium manganese oxide content of other impure phases, less than 0.1% and good in performance. |
