ABSTRACT: Contact interaction of solid electrolytes based on the Li8ZrO6 material and the Li8-2xMxZrO6 (M=Mg,Sr), Li8-xZr1-xVxO6 solid solutions with the molten lithium metal was studied experimentally for the first time. In accordance with the performed experiments regarding the kinetic stability to molten lithium, the compositions of the Li8-2xMxZrO6 (M=Mg,Sr) and Li8-xZr1-xVxO6 were recommended for use as solid electrolytes in high- and middle temperature (573 K) LCPS.
