| Outline of Final Research Achievements |
First, we investigated an experimental method with excellent reproducibility of the amount of gold oxide. As a result, combination of metal plate, repeated electrochemical oxidation/reduction cycles at an appropriate potential, and anodization with a constant current using two electrodes enabled a good reproducibility.
Assuming that the amount of electricity for prepared gold oxide film is determined by measurement of electricity during cathodic potential sweep of the gold oxide film, the discharge is measured at a current density (0.15 mAcm^-2) at which the time for complete discharge of this gold oxide is 1 hour. As a result, 0.92 V vs. SHE was maintained and the potential dropped sharply just before the complete discharge. It was confirmed that the potential of 0.92 V vs. SHE was maintained until just before the completion of discharge even when the discharge rate was doubled and halved.

これまで未報告であった，金酸化物の定電流放電挙動を得ることができた．その時の電位は0.9 V vs. SHEと非常に高く，完全放電直前まで維持することが判明した．現在および今後のエネルギー問題に対処するために，様々な目的に応じた多様な電池の開発が必要であるため，本研究課題で得られた成果は，新しい電池の材料としてエネルギー問題の解決の一石となることが期待される．
