All solid-state thin-film supercapacitors (TFSCs) were fabricated using RuO2 electrodes grown at oxygen gas flow ratios of 10% and 30%. Room-temperature charge-discharge measurements of the RuO2/LiPON/RuO2 TFSCs showed that after one cycle, the specific capacitances per volume were 30.6 and 23.5 mF/cm2 μm for the 10% and 30% TFSCs, respectively. It was shown that as the cycle number increased, the capacitance of the 10% TFSC was degraded rapidly, while that of the 30% TFSC was degraded slowly.
