<p>An Na/molten salt cell comprises a cathode active material containing sodium (Na) as an essential component, an anode active material containing sulfur (S) or a molten salt as of sodium polysulfide as essential components, and a solid electrolyte which is interposed between the cathode and anode active materials and through which Na ions permeate. A battery consisting of such cells has means which detects the temperature in the battery, means which stores the temperature information of the battery and detects an abnormal cell, and means which disconnects the abnormal cell from the normal cells connected in series and parallel to the abnormal cell. An abnormal cell is detected and disconnected from the other normal cells, the operation of the normal cells is continued, and then, the abnormal cell can be easily exchanged.</p> |
