| Outline of Final Research Achievements |
We applied halogen (e.g., bromine)-redox systems to charge-storage electrode reactions. Activated carbon was utilized to keep reversible reactions of halogens in its micropores. An electric double layer capacitor (EDLC) was designed with a positive electrode based on such redox reactions involved mainly by bromide. Furthermore, a hybrid capacitor with a lithium metal anode and a lithium-ion battery with a graphite anode were proposed by combining bromine redox-based positive. Optimum electrolytes were investigated for the various cell systems. We have also developed reversible battery systems with a magnesium metal anode with bromide-based electrolytes. We attempt to apply such novel magnesium-bromine systems to usual, closed rechargeable magnesium batteries as well as magnesium air batteries. Our new projects will focus on these novel systems.
