Regulating Li deposition by constructing LiF-rich host for dendrite-free lithium metal anode

Our research demonstrates the feasibility of a novel, simple and safe method to prepare LiF-rich Li anode, which possesses high Li ions diffusion rate and cuboid surface structure simultaneously. The LiF host guides the Li metal deposit into a smooth and wafer-like morphology. Particularly, the scaly deposition feature under high cycling capacity make for a dendrite-free Li anode and thus enhance the performance of lithium metal batteries.216
