Abstract: | The effect of partial substitution of Zr4+ ions for Ge4+ ions in highly conducting lithium-cationic solid electrolyte Li3.75Ge0.75P0.25O4 is studied. It is found that the introduction of zirconium ions considerably raises the conductivity of basic electrolyte in the high-temperature range. For the optimal composition, the conductivity is 2.82 × 10−1 S cm−1 at 400°C and 1.55 S cm−1 at 700°C. Possible reasons for the effects are discussed. |
