    摘要: A molten sodium secondary cell charges at a high temperature and discharges at a relatively lower temperature. The cell includes a sodium anode and a cathode. A sodium ion conductive solid membrane separates the cathode from the sodium anode and selectively transports sodium ions. A solar energy source includes a photovoltaic system to provide an electric charging potential to the sodium anode and the cathode and a solar thermal concentrator to provide heat to the cathode and catholyte composition to cause the molten sodium secondary cell to charge at a temperature in the range from about 300 to 800 °C. The cell has a charge temperature and a charge voltage and a discharge temperature and a discharge voltage. The charge temperature is substantially higher than the discharge temperature, and the charge voltage is lower than the discharge voltage.

    摘要: An intermediate temperature sodium-halogen secondary cell that includes a negative electrode compartment housing a negative, molten sodium-based electrode and a positive electrode compartment housing a current collector disposed in a highly conductive molten positive electrolyte. A sodium halide (NaX) positive electrode is disposed in a molten positive electrolyte comprising one or more AlX3 salts, wherein X may be the same or different halogen selected from Cl, Br, and I, wherein the ratio of NaX to AlX3 is greater than or equal to one. A sodium ion conductive solid electrolyte membrane separates the molten sodium negative electrode from the molten positive electrolyte. The secondary cell operates at a temperature in the range from about 80° C to 210° C.
