In order to facilitate the subsequent coating with water washing, the low alkali material was crushed into a low alkali material with an average particle size of 4~13μm. Coating The washing material and the low alkali material are put into the coating mixer according to the mass ratio of 1~2:1 to get the coating material.
PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC magnetic Preferably, in order to make the coating effect better, the coating agent is also added to the mixture of the washing material and the low alkali material.
The amount of coating agent added in the whole mixing system is 0.01~3%. Further, the coating agent includes at least one of an aluminum oxide, an aluminum hydroxide, a boron oxide, and a tungsten oxide. Sintering the coating MATERIAL is placed in the temperature of 200~600℃ (such as 200℃, 300℃, 400℃ or 600℃) in the oxygen atmosphere sintering, PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC removal of iron to obtain high nickel ternary cathode material.
The high nickel ternary cathode material was produced by rolling, batch mixing, screening, iron removal and packaging. The high nickel ternary cathode MATERIAL is prepared by PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC preparation method, which has higher discharge efficiency and cycle retention.
