While battery storage at low temperatures results in low SEI growth rates, Li plating becomes the dominant aging mechanism during charging. Li plating occurs instead of chemical intercalation into the anode at negative anode potentials vs. Li/Li + during charging. It is caused by poor electrode kinetics at high currents, especially at low temperatures [21, 31].
