As these batteries reach the end of their life cycle, efficiently utilizing their residual value has become a key issue that needs to be resolved. This paper reviews the key issues in the cascade utilization process of retired lithium batteries at the present stage.
From both theoretical and practical aspects, the cells with average voltage in the battery pack are selected as representative cells and their residual energy is estimated as the residual energy of the battery pack at the current moment.
Currently, the methods for estimating the residual capacity of retired batteries are mainly classified into two main categories: direct and indirect estimation methods. Direct estimation methods include (i) CC; (ii) OCV; and (iii) Electrochemical impedance spectroscopy (EIS).
Cascade utilization of retired batteries is considered one of the most promising disposal methods. However, to maximize the residual value of these batteries before cascade utilization, it is necessary to estimate their residual capacity and perform consistency sorting.
