Improper treatment of LIBs waste can affect the quality of the environment. On the other hand, LIBs waste is a valuable source of many metals. In recent years, intensive efforts have been made to develop a hydrometallurgical recycling process for cathode materials, paying particular attention to the leaching process. The leaching of cathode material from spent LIBs is a heterogeneous reaction occurring at the solid-liquid interface. Various kinetic equations are used to process experimental results and determine the kinetic parameters of the leaching process. In this study, an overview of systems in which a shrinking core model is applied to describe the leaching process of nickel-, manganese- and cobalt-based cathode materials (LiNixMnyCozO2) is given.LIBscathode materialkineticsheterogeneous reactionsconferenceObject
