In situ generated air-stable inorganic-rich SEI of lithium anodes for dendrite-free lithium metal batteries

A solid electrolyte interphase (SEI) was constructed through a simple hot rolling process, with LiF, LiOH, Li 2 O, and Li x SiF y phases distributed to rapidly conduct Li + and Mg metal phase as nucleation sites to guide Li + for deposition. The dense SEI also blocked air and improved the air durability.
