| Outline of Final Research Achievements |
The purpose of this study was to clarify the advantages and problems of aqueous Na-air cells, and to solve these problems. A good compatibility of nanoporous gold electrode with the present system was demonstrated for the first time. This enable us to directly compare nonaqueous and aqueous system, clarifying the advantages of the present system. In addition, the effect of introducing the ionic liquid in to anolyte and the good performance catalyst in to air electrode were verified. Furthermore, a dense electrolyte sheet, which contributes to reducing total resistance of the battery, was successfully prepared. The integration of these new knowledge and techniques can contribute not only to the improvements in performances of aqueous Na-air cells but also to development of other kinds of batteries as well as to systematic understanding of Li and Na chemistries.
