The preparation method of high nickel ternary cathode MATERIAL PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC includes: the coating material is obtained by mixing washing material with low alkali material according to the mass ratio of 1~2:1; The coating material is sintered; The water washing material is the high alkali material obtained after the precursor is mixed with lithium hydroxide and washed, and then the water is removed. The ratio of metal content in the precursor to lithium molar mass in lithium hydroxide is 1:1.01~1.08.
The low alkali material is obtained by sintering the precursor with lithium hydroxide according to the ratio of metal element content to molar mass 1:0.85~1.00. PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC treatment of high nickel ternary cathode material refers to the nickel molar content is greater than 60% of the total molar content of metal elements other than lithium.
The alkali content of the high alkali material is about 6500~12000ppm, and the alkali content of the washed material after washing is about 3500~5500ppm; The alkali content of low alkali feed is about 3000~5000ppm. The base content here mainly refers to lioh+li2co3. The high alkali MATERIAL is washed for alkali reduction, while the low alkali material is not washed. PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC field for the final product of ternary cathode material, the washing part is reduced, which reduces the influence of the washing process and the drying process after washing on the ternary cathode material product.
