In-Situ Constructing A Heterogeneous Layer on Lithium Metal Anodes for Dendrite-Free Lithium Deposition and High Li-ion Flux.

Constructing efficient artificial solid electrolyte interface (SEI) film is extremely vital for the practical application of lithium metal batteries. Herein, a dense artificial SEI film, in which lithiophilic Zn/Li Zn are uniformly but nonconsecutively dispersed in the consecutive Li -conductors of Li SiO , Li O and LiOH, is constructed via the in situ reaction of layered zinc silicate nanosheets and Li. The consecutive Li -conductors can promote the desolvation process of solvated-Li and regulate the transfer of lithium ions.
