The process of depositing metallic lithium on the surface of a battery''s negative electrode, typically graphite, during charging is referred to as lithium plating. When the battery is charged quickly or at low temperatures, this process causes metallic lithium crystals to form instead of lithium-ions intercalating in the electrode structure.
