| titleOfInvention | Ternary cathode precursor and preparation method thereof |
| abstract | The present application relates to the technical field of battery materials, and provides a ternary positive electrode precursor whose chemical formula is Ni x Co y Mn 1‑x‑y CO 3 ·aZr 3 (BO 3 ) 4 ·bNd 2 (CO 3 ) 3 , 0<x<1, 0<y<1, 1‑x‑y>0, 0.0005<a<0.5, 0.0005<b<1. The ternary positive electrode precursor is a nickel-cobalt-manganese carbonate material co-doped with Zr, B, and Nd. Compared with the positive electrode material prepared by using an element-free nickel-cobalt-manganese carbonate material, the three-component cathode material provided by the present application The cathode material prepared from the original cathode precursor showed better cycle performance. The present application also provides a method for preparing the above-mentioned ternary positive electrode precursor, including: in an inert gas environment, co-precipitating a nickel source, a cobalt source, a manganese source, a boron source, a zirconium source, a neodymium source and a precipitant in a solution reaction to obtain a ternary cathode precursor. |
