| titleOfInvention | A kind of positive electrode material, its preparation method and lithium ion battery |
| abstract | The invention relates to the field of batteries, in particular to a positive electrode material, a preparation method thereof and a lithium ion battery. The preparation method of the positive electrode material includes the following steps: (A) mixing a precursor with a lithium-containing compound, performing first sintering, crushing and sieving the sintered product to obtain a primary sintering material; the precursor is nickel Cobalt-manganese precursor and/or nickel-cobalt-aluminum precursor; (B) uniformly mixing the primary sintering material with an organic substance containing hydroxyl or carboxyl groups, and performing secondary sintering to obtain a positive electrode material. The preparation method of the present invention adopts twice sintering, which reduces the residual alkali content of the positive electrode material and improves its processing performance at the same time. |
