Beschreibung
Zusammenfassung:It is provided a lithium metal anode coated with a protective monolayer disposed on at least a portion of the lithium metal anode, the protective monolayer consisting of a polymer; at least one inorganic particle selected from the group consisting of Al2O3, MnO, MnO2, SiO2, TiO2, ZnO, ZrO2, Fe2O3, CuO, a silicate, an aluminosilicate, a borosilicate, and an oxysalt, or any one of the mentioned inorganic particles which are functionalized; wherein the protective monolayer has a thickness from 0.01 to 10 μm, the inorganic particles have an average diameter from 1 to 500 nm, and the at least one inorganic particle is in an amount of 0.01 to 30 wt % related to the amount of polymer. It is also provided a method for the preparation of the protected anode, as well as a lithium metal battery comprising it.
