摘要

Lithium plating on graphite anode is triggered by harsh conditions of fast charge and low temperature,which sig-nificantly 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 detect-ing methods and hazard of Li plating.Then,approaches to suppress Li plating are dis-cussed,including anode surface modification,electrolyte composition optimization and development of optimal charge.strategies.Finally,we con-clude 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.
