Abstract:

As an important lithium-ion battery, ternary nickel-cobalt-lithium manganese (NCM) battery has a broad development prospect and application value. This paper summarizes the advantages of ternary lithium-ion battery compared with traditional battery, analyzes the components of ternary battery, and focuses on the different recycling methods and reaction mechanisms of ternary cathode materials. The application prospect of NCM ternary lithium-ion battery is prospected. Combined with the new process route of technological innovation and development projects, the problems existing in the present recycling methods, such as the difficulty in separating cathode active substances from aluminum foil and the easy generation of secondary waste liquid, are effectively solved.
