Prelithiation has been widely accepted as one of the most promising strategies to compensate for loss active substance and improve initial Coulombic efficiency in silicon-based anodes advanced high-energy-density batteries. But because their unstable solid electrolyte interface (SEI) layer low efficiency, they expand volume during prelithiation react with moisture, which makes commercialization a difficult process. Herein, we have developed strategy using lithium bis(fluorosulfonyl)imide (LiFSI) treatment eliminate redundant generate LiF-based inorganic compounds on surface prelithiated electrode. Such method not only reduces reactiveness anode but also enhances ionic conductivity SEI. The rich LiF works an artificial SEI, according electrochemical evaluation, silicon treated LiFSI can reach 92.9%. This technique increases battery’s energy density its cycle stability, resulting superior capacity retention longer cycling life.
