摘要

通过向电解质(GDC)中掺杂不同质量分数(10%,20%,30%)的碳酸盐(Li2CO353mol%与NaCO347mol%)得到复合电解质。通过电导率测试、扫描电镜(SEM)测试对此复合电解质进行电化学性能表征。将此复合电解质与NiO复合得到阳极粉体,将此复合电解质和Li处理过的NiO复合,得到阴极粉体。将以上制备的阳极、阴极、电解质用干压法压制,得到阳极支撑的单电池片。测试单电池的电化学性能。结果表明,含碳酸盐质量分数为30%的GDC作为电解质制备的单电池,其功率密度最高,在600℃温度下为1400mW/cm2

Abstract:

Composite electrolytes were prepared by doping carbonates (Li2CO353 mol% and NaCO347mol%) with different mass fractions (10%, 20%, 30%) into electrolyte (GDC). The electrochemical properties of the composite electrolyte were characterized by conductivity test and scanning electron microscopy (SEM). Anode powder was prepared by doping composite electrolytes into NiO, and the cathode powder was obtained by compounding the composite electrolytes with Li-treated NiO.The anode, cathode and electrolyte prepared above were pressed by dry pressure method to obtain a single cell supported by the anode. The performance of the cell was characterized later. The results of electrochemical performance of single cell show that GDC with 30% carbonate has the highest power density, which is 1400 mWcm-2at 600 C.
