| Outline of Final Research Achievements |
In general, there are few cathode materials that can accommodate polyvalent cations, which leads to the lowering of the versatility of the polyvalent-metal storage battery. In this study, we have proposed a new concept of storage battery, i.e., dual-salt battery, which employs polyvalent metal (such as magnesium) as an anode material. The present deal-salt battery combines the cathode materials for Li ion batteries (or sodium ion batteries) with the polyvalent metal anode materials. We have fabricated a Daniell-type test cell using the cathode material (LiFePO4) for LIBs and Mg metal anode, and confirmed that such a battery can be discharged and charged stably. In order to enhance the energy density, we have tested whether the Chevrel compounds can accommodate both Mg and Li cations. Thus, the dual-salt storage batteries have been examined by various combination of cathode and anode materials.
