The disclosure discloses a nickel cobalt manganese hydroxide, a cathode material, a preparation method thereof and a lithium ion battery. The nickel cobalt manganese hydroxide comprises a core and an outer layer covering the outside of the core. The core comprises flaky particles, the Dparticle diameter of the flaky particles in the core is 5-8 &#x3bc;m, and the Dparticle diameter of particles in the outer layer is 0.1-5 &#x3bc;m.

Nickel cobalt manganese hydroxide, cathode material, preparation method thereof and lithium ion battery

Transition metal hydroxide and oxide, method of producing the same, and cathode material containing the same are disclosed. One method includes coupling an alkaline solution to a transition metal salt solution under an inert gas atmosphere, whereby the alkaline solution includes an additive. A transition metal oxide may be prepared by heating the transition metal hydroxide under an oxygen gas atmosphere. Cathode materials for lithium-ion batteries may be prepared incorporating the transition metal hydroxide and oxide embodiments disclosed herein.
