ABSTRACT: Contact interaction of solid electrolytes based on the Li₈ZrO₆ material and the Li_8-2xM_xZrO₆ (M=Mg,Sr), Li_8-xZr_1-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 Li_8-2xM_xZrO₆ (M=Mg,Sr) and Li_8-xZ_r1-xVxO₆ were recommended for use as solid electrolytes in high- and middle temperature (573 K) LCPS.
