Abstract: 

The method of thermodynamic simulation was used to establish equilibrium products of chemical interactions in the systems lithium metal – solid electrolyte (SE). Calculations were performed at 25–165o C for Li6BeO4, LiYO2, LiScO2, Li5SiN3, Li8SiN4, Li3AlN2, Li2SO4, Li2ZrO3, Li4ZrO4, Li8ZrO6 and Li5AlO4 solid electrolytes. The prediction of solid electrolyte stability in respect to Li metal was given well. As a result, lithium-conducting solid electrolytes under investigation were sorted into three groups as follows: 1) thermodynamically stable in respect to Li metal solid electrolytes; 2) solid electrolytes forming passive layer in contact with Li metal; and 3) unstable in respect to Li metal solid electrolytes.
