摘要：
In this study, 10 mol% Cu2+-doped SnP2O7 was compounded with K2CO3 to prepare Sn0.9Cu0.1P2O7/KPO3 composite electrolyte. The structure, morphology and medium temperature electrical properties of Sn0.9Cu0.1P2O7/KPO3 were investigated. The Raman spectrometer result showed that Sn0.9Cu0.1P2O7/KPO3 was composed of pyrophosphate and metaphosphate groups. The maximum conductivity of Sn0.9Cu0.1P2O7/KPO3 reached 6.6 x10(-2) S.cm(-1) at 700 degrees C. The maximum power density of Sn0.9Cu0.1P2O7/KPO3 reached to 131 mW.cm(-2) at 700 degrees C.
