Pyrometallurgical options for recycling spent lithium-ion batteries: A comprehensive review

Makuza, Brian, Tian, Qinghua, Guo, Xueyi, Chattopadhyay, Kinnor, Yu, Dawei·2021·Journal of Power Sources

Abstract

Abstract Lithium-ion batteries (LIBs) have attracted increasing attention for electrical energy storage applications in recent years due to their excellent electrochemical performance. The unprecedented growth trajectory in lithium-ion battery manufacturing perpetuated by the inception of electric vehicles (EV) results in a vast amount of spent LIBs reaching their end of life (EOL). From the perspective of resource circulation, procurement, and sustainability with an insight into the circular economy, an effective recycling system must be developed to recycle the spent LIBs. This paper provides a comprehensive overview of the current status of pyrometallurgical options for recycling spent LIBs. In particular, this study summarizes the thermal pretreatment methods used to recover the active cathode material and then discusses the developed extractive pyrometallurgical options for recycling spent LIBs. A summary is presented on some recent examples of laboratory and industrial-scale recycling processes to demonstrate the practical applications of pyrometallurgical options for recycling. Finally, the review sheds light on the battery recycling legislation, and challenges and future outlook for recycling LIBs are also discussed.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
