In order to enable fast-charging ability in batteries, researchers have attempted to enhance the mass transfer of electrolytes and charge transfer in electrodes, with extensive research carried out on the former compared to the latter. Generally, when charging surpasses rate of intercalation, Li + plating occurs on graphite electrodes.
