| description | The stability of Li<sub>3.8</sub>Ge<sub>0.9</sub>S<sub>0.1</sub>O<sub>4</sub> lithium-conducting solid electrolyte versus lithium metal and Li–V bronze Li<sub>1.3</sub>V<sub>3</sub>O<sub>8</sub> is studied in the present research. Isothermal heat treatment and thermal analysis of the mixtures of Li<sub>1.3</sub>V<sub>3</sub>O<sub>8</sub> and Li<sub>3.8</sub>Ge<sub>0.9</sub>S<sub>0.1</sub>O<sub>4</sub> powders indicate that there is no interaction between them below 300–350 °C. Moreover, Li<sub>3.8</sub>Ge<sub>0.9</sub>S<sub>0.1</sub>O<sub>4</sub> solid electrolyte is stable versus lithium at 100 °C for 240 h. A model of a lithium-ion power source with a Li<sub>1.3</sub>V<sub>3</sub>O<sub>8</sub>-based cathode and a lithium metal anode is assembled and tested. The data obtained show that Li<sub>3.8</sub>Ge<sub>0.9</sub>S<sub>0.1</sub>O<sub>4</sub> can be used in all-solid-state medium-temperature lithium and lithium-ion batteries. |
