英文摘要：

Na2PbO2and Na2ZnO2were synthesized through PbO、ZnO solidly reacting with NaOH, respectively, and were characterized using XRD. The solid electrolyte cells Pt∣PbO, Na2PbO2‖β(β″)-Al2O3‖NaCrO2, Cr2O3∣Pt and Pt∣ZnO, Na2ZnO2‖β(β″)-Al2O3‖NaCrO2, Cr2O3∣Pt were assembled usingβ(β″)-Al2O3 as solid electrolyte. The formation free energies of Na2PbO2 and Na2ZnO2 are calculated through measuring the electromotive force (EMF) of cells measured. The relationship between formation free energy and temperature (700?1273 K) were gotten.
