固体电解质Li10GeP2S12在室温下表现出12 mS/cm的高锂离子电导率。由于Li10GeP2S12具有较高的离子电导率，因此使用Li10GeP2S12电解质的全固态电池具有较高的充放电性能。在本研究中，使用Li10GeP2S12构建了全固态电池，并对其电池性能进行了测试。使用Li10GeP2S12电解液的电池在大倍率电流放电条件下，放电容量明显高于使用75Li(2)S中心点25P(2)S(5)玻璃电解液的电池。(C)日本电化学学会，版权所有。
A solid electrolyte, Li10GeP2S12, exhibits a high lithium ionic conductivity of 12 mS/cm at room temperature. Because of its high ionic conductivity, high charge-discharge performance would be expected for the all-solid-state batteries using the Li10GeP2S12 electrolytes. In this study, all-solid-state batteries using Li10GeP2S12, were constructed and their battery performances were examined. The batteries using the Li10GeP2S12 electrolyte showed higher discharge capacities than those with glass electrolyte, 75Li(2)S center dot 25P(2)S(5), particularly under the high-rate current discharge.
