Lithium metal batteries (LMBs) are a promising candidate for next-generation energy storage devices. However, the high irreversibility and dead Li accumulation of lithium anode caused by its fragile original solid electrolyte interface (SEI) seriously hinder practical application LMBs. Herein, facile slurry-coating one-step thermal fluorination reaction method is proposed to construct 3D structural LiF-protected Li/G composite anode. The existence LiF protection layer convincingly confirmed function skeleton discussed in detail. results superior electrochemical performance improving utilization suppressing symmetric full coin cells. Moreover, 0.85 Ah pouch cell strictly following parameters battery industry can work stably 140 cycles with gradual internal resistance increase. This novel indicates strategy lithium/carbon anodes LMBs, presented this paper offers new construction anodes.
