- 論文の詳細を見る
Coin-type of air secondary batteries using hydrogen storage alloys as the negative electrode's material were designed and fabricated, and the charge-discharge characteristics were evaluated under constant current operation. The positive electrode consisted of a nickel-based gas diffusion electrode using Ir2Bi2O7－z as oxygen evolution and reduction catalyst. A stable charge and discharge voltages were observed, and the discharge voltage and power density were improved by using a membrane separator, in which an alkaline solution was impregnated, between the positive and negative electrodes. A high power density up to 81 W dm－3 and a good charge-discharge cycling behaviors were also obtained.
