| titleOfInvention | A kind of high nickel ternary lithium ion battery positive electrode material and preparation method thereof |
| abstract | The invention discloses a positive electrode material for a high-nickel ternary lithium ion battery and a preparation method thereof. A high-nickel ternary lithium-ion battery cathode material LiNi x Co y Sc z O 2 ( 0.85≤x≤0.90 , y≤0.1, z≤0.1 and x+ y+z=1), Sc doping reduces the degree of mixing of lithium-nickel ions and enhances the stability of the crystal structure, and improves the cycle performance of LiNi x Co y Sc z O 2 ; the use of chelating agents to achieve the molecular level of reaction raw materials. Mixing uniformly, lowering the reaction temperature and shortening the reaction time, is conducive to obtaining LiNi x Co y Sc z O 2 with fine particles, significantly shortens the diffusion path of lithium ions in LiNi x Co y Sc z O 2 solid particles, and improves the lithium ion diffusion path. The electrochemical kinetic performance improves the rate performance of the material, and has the advantages of high capacity, long life and excellent rate performance. |
