Rational construction Ag/LiF/sulfide rich protective layer for remarkably enhancing the stability of Li metal anodes

Li anode with a multicomponent protective layer (Ag/F/S-Li) protective layer at molecular level are designed and prepared. The Ag0 in Ag/F/S-Li has the ability to induce uniform Li+ distribution, while LiF/sulfide layer enable to reduce the side reaction between electrolyte and Li metal. This Ag/F/S-Li anode can cycle stably for 2000h.
