Abstract

Lithium-ion batteries have a limited lifespan, and disposing of them in large quantities can cause serious environmental problems. This study focused on the simulation of leaching solutions from waste ternary lithium battery cathode materials. A variety of precipitants were introduced with the objective of progressively leaching and separating valuable metals. The positive electrode material of LiNi1/3Co1/3Mn1/3O2 lithium-ion battery was synthesized by solid phase grinding. The charge-discharge capacity, cyclic stability, electrochemical impedance, and cyclic voltammetry of the prepared composites were analyzed. The results show that the initial charge-discharge ratio at 0.2 C is 171.7 mA h g–1, and the initial ratio increases to 65.87% after 50 cycles. The successful synthesis of ternary positive electrode materials proves the feasibility of preparing ternary positive electrode materials by solid phase grinding method and step separation method. It points out the development direction for the recycling and reuse of ternary cathode materials for waste lithium-ion batteries.
