Research Progress of Lithium Plating on Graphite Anode in Lithium-Ion Batteries

Lithium plating on graphite anode is triggered by harsh conditions of fast charge and low temperature, which significantly accelerates SOH (state of health) degradation and may cause safety issues of lithium ion batteries (LIBs). This paper has reviewed recent research progress of lithium plating on graphite anode. Firstly, we summarize the forming mechanisms of Li plating with corresponding influence factors, the detecting methods and hazard of Li plating. Then, approaches to suppress Li plating are discussed, including anode surface modification, electrolyte composition optimization and development of optimal charge strategies. Finally, we conclude and propose the remaining challenges and prospects in terms of mechanism research, detecting approaches, and suppressing methods of Li plating. This review highlights the development of Li plating research and plays a guiding rule of further study on Li plating in LIBs.

Automated summary

Lithium plating on graphite anode is accelerated by fast charge and low temperature, leading to degradation of the battery's state of health (SOH) and potential safety risks. Various methods such as anode surface modification, electrolyte optimization, and charge strategy development are discussed to suppress lithium plating. Remaining challenges include mechanism research, detection methods, and further development of suppression techniques.
