Lithium metal batteries represent a cutting-edge class of energy storage devices, yet the high surface diffusion barrier lithium prompts preferential Li+ accumulation and deposition, fostering growth dendrites. To address this challenge, straightforward solvent-based approach is employed to create LiF-rich protective layer on anode. The uniform LiF interface facilitates transport effectively induces plating stripping while inhibiting formation Notably, symmetric battery incorporating anode modified with appropriate demonstrates substantially enhanced cycling performance. Importantly, full cell matched LiFePO4 displays an initial capacity 146.3 mAh g-1 retention rate 92.7% after 300 cycles. Its practical application has also been verified in for PEO solid-state batteries. This work underscores potential boost dendrite-free
