“…[ 4,6–8 ] Regulating Li + solvation structure, [ 8 ] introducing an artificial coating layer on graphite surface, [ 6,9 ] modifying graphite bulk materials, [ 6,10 ] and optimizing charging protocols [ 2 ] are strongly considered recently. Particularly, precoating the surface of graphite particles with thin polymers, [ 11 ] inorganic compounds, [ 6,9,12,13 ] and hybrid organic/inorganic layers is explored, [ 14 ] which can effectively inhibit the decomposition of electrolyte, increase initial Coulombic efficiency, and reduce irreversible capacity loss. Most attention is drawn on the characterization of the coating layers and the improved electrochemical performance of the graphite electrodes.…”

“…30,31 Hence several papers report coatings to prevent lithium plating on graphite such as amorphous Al 2 O 3 , TiO 2 and polyvinylidene difluoride (PVDF). [32][33][34] A recent paper reported an anode combining Li plating/stripping and graphite intercalation/ deintercalation using a combination of dual salt and mechanical pressure to stabilise the electrode operation. 35 Here we propose instead to coat graphite with a lithiophilic layer in conjunction with an organo-gel electrolyte to promote reversible Li plating (Fig.…”

“…Luo demonstrated a proof‐of‐concept graphite anode containing a polymer coating that effectively mitigated Li dendrite formation under harsh lithiation conditions. [ 81 ] It was revealed that Li dendrites with dimensions ranging from a few tens nanometers to microns occurred readily on granular graphite anode either under 20% over‐lithiation at 0.2 C or fast lithiation up to 10 C rate. In contrast, the graphite anode with a conformal thin coating of high‐polarity β‐phase polyvinylidene difluoride (PVDF) on graphite particles exhibited dendrite‐free Li plating under either condition.…”

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.
