Lithium nickel cobalt manganese oxide is one of the key materials for lithium-ion batteries. Lithium cobalt oxide is currently the most widely used battery material, but cobalt resources are increasingly scarce and expensive, and lithium cobalt oxide batteries have potential safety hazards during use.

Lithium nickel cobalt manganese oxide replaces more than two-thirds of cobalt in lithium cobalt oxide with relatively inexpensive nickel and manganese. The cost advantage is very obvious. Compared with other lithium-ion battery cathode materials, lithium manganate and lithium iron phosphate, Lithium nickel cobalt manganese oxide materials and lithium cobalt oxide are very close in terms of electrochemical performance and processing performance, making lithium nickel cobalt manganese oxide materials become a new battery material and gradually replace lithium cobalt oxide, becoming the darling of a new generation of lithium-ion battery materials.

The preparation method of lithium nickel cobalt manganate mainly adopts high temperature solid phase synthesis method and co-precipitation method. At present, manganese compounds, nickel compounds and lithium cobalt oxide and lithium hydroxide are mainly used as raw materials. Through hydrothermal reaction, a precursor with good combination of lithium, manganese, cobalt and nickel is obtained, and then the precursor is supplemented with a lithium source and ground. The precursor is calcined to obtain lithium nickel cobalt manganese oxide. With the increasing tension of global resources and the pressure of the environment, battery materials must follow the route of fixed-line circulation.
