| titleOfInvention |
A high-capacity, long-cycle nickel-cobalt-manganese ternary positive electrode material and preparation method thereof |
| abstract |
The invention discloses a high-capacity, long-cycle nickel-cobalt-manganese ternary positive electrode material, the grain size is 200nm-300nm; the residual stress of the ternary positive electrode material is 0.15-0.3. According to the preparation method of the present invention, the ternary positive electrode material precursor and the lithium source are mixed according to the stoichiometric ratio; The temperature is 5℃～20℃; the sintered material is cooled and sieved to obtain a high-capacity, long-cycle nickel-cobalt-manganese ternary positive electrode material. The grain size of the ternary positive electrode material of the present invention is 200 nm to 300 nm, and the residual stress is 0.15 to 0.3. The ternary positive electrode material with the residual stress within this range can ensure that the battery has good capacity and cycle performance at the same time. |
