| 内容記述 | Various metal chlorides were tested as possible cathode materials for sodium-metal batteries (in addition to Fe and Ni chlorides, which have been already developed to a stage of commercialization), using an electrochemical cell consisting of a pyrex tube, heated to 250 C, with the metal wire as working electrode, concentric Ni foil as counterelectrode, and high-purity Al as reference electrode. In particular, the aim of this study was to identify metal chlorides insoluble even in neutral melts, possible at the interface during overcharge, in order to eliminate the failure mode of the cell through a cationic exchange of the dissolved metal ions with sodium beta-double-prime alumina solid electrolyte. Results indicate that Mo and Co are likely alternatives to FeCl2 and NiCl2 cathodes in sodium batteries. The open circuit voltages of Na/CoCl(x) and Na/MoCl(x) cells at 250 C would be 2.55 V and 2.64 V, respectively. |
