| titleOfInvention | A kind of high nickel type single crystal lithium ion battery cathode material and preparation method |
| abstract | The invention discloses a method for preparing a positive electrode material for a high-nickel single crystal lithium ion battery and the prepared positive electrode material. The preparation method includes: sintering a precursor and a lithium source in air or oxygen; sintering the obtained precursor metal oxide A and a lithium source. Lithium oxide is mixed evenly with the molar ratio of lithium and metal ions in A of 1.0-1.1, and is sintered in oxygen to obtain B; The oxidizing agent is used to make the mass percentage of 0.5-3%, and stirring at 10-50°C for 10-30min; filtering out and drying, secondary sintering in oxygen, and sieving to obtain high-nickel single crystal lithium-ion battery positive electrode material LiNi x Co y Mn z M t O 2 ; 0.60≤x≤0.90, 0.05≤y≤0.20, 0≤z≤0.20, 0≤t≤0.005, and x+y+z+t=1, M is Al, Ca , one of Mg, Zr, Ti, Sr, Mo, W, Ce. The high-nickel single crystal lithium ion battery positive electrode material of the present invention contains divalent nickel, and has few surface impurities lithium and impurities, and has good processing performance, high capacity and good cycle performance when making batteries. |
