Low-concentration electrolyte with lithium nitrate as the sole salt for constructing a LiF/Li 3 N inorganic composite SEI and enabling stable lithium metal battery cycling

A novel low-concentration electrolyte with lithium nitrate as the sole salt enables flame-retardant lithium metal batteries featuring a 4.4 V stability window, dendrite-free Li deposition, and stable cycling through a LiF/Li 3 N SEI.
