Abstract: As the main cathode material, LiNixCoyMnzO2 ternary cathode material has more advantages than lithium cobalt oxide material in terms of safety, life and cost.It is widely used in new energy vehicles, ships, energy storage and many other fields, and has become the most potential positive electrode material at the present stage.This paper summarizes the design of ternary cathode materials and the mainstream methods of industrialization, analyzes the main influencing factors of ternary cathode materials from design, raw materials, precursors and finished products in detail, and looks forward to the future development trend of "cobalt-free" ternary cathode materials.
