NICKEL-COBALT-MANGANESE HYDROXIDE PRECURSOR HAVING RADIAL POROUS STRUCTURE, AND PREPARATION METHOD THEREFOR

The present application belongs to the technical field of lithium-ion battery materials. Disclosed are a nickel-cobalt-manganese hydroxide precursor having a radial porous structure, and a preparation method therefor. The chemical formula of the nickel-cobalt-manganese hydroxide precursor having a radial porous structure is NixCoyMn1-x-y(OH)2, wherein 0.5≤x≤1, and 0≤y≤0.4. Primary particles in the nickel-cobalt-manganese hydroxide precursor are fine and thin, and are mutually staggered and associated to form radial secondary particles with a loose and porous interior, such that the secondary particles have a relatively high specific surface area and can provide more transmission channels for lithium ions during the sintering process with a lithium source; in addition, the intercalation and deintercalation resistance of lithium ions are reduced during the charging and discharging process, the transmission distance of lithium ions is shortened, and the transmission rate is increased.
