▎ 摘  要

NOVELTY - Coating lithium nickel cobalt aluminum oxide high-nickel ternary material comprises dissolving and dispersing acetate of nickel cobalt aluminum in ultrapure water, adding oxalic acid to precipitate and react to obtain precursor solution, weighing and coating material and coating raw material, configuring to cover raw material solution, coating raw materials, adding coating raw product solution to precursor solution for precipitation conversion reaction at constant temperature, stirring and aging, adding coating material solution to precursor solution, performing precipitation reaction, stirring, aging, filtering, drying and calcining. USE - The method is for coating lithum nickel cobalt aluminum oxide high-nickel ternary material. ADVANTAGE - The coating method of high nickel material LiNi0.80Co0.15Al0.05O2 forms uniform coating material and NCA material, uniform coating body, effectively preventing the coating material falling, crushing, and circulating stability is improved by more than 30% by precipitation conversion reaction.
