    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: The present invention provides a molten sodium secondary cell. In some cases, the secondary cell includes a sodium metal negative electrode, a positive electrode compartment that includes a positive electrode disposed in a liquid positive electrode solution, and a sodium ion conductive electrolyte membrane that separates the negative electrode from the positive electrode solution. In such cases, the electrolyte membrane can comprise any suitable material, including, without limitation, a NaSICON-type membrane. Furthermore, in such cases, the liquid positive electrode solution can comprise any suitable positive electrode solution, including, but not limited to, an aqueous sodium hydroxide solution. Generally, when the cell functions, the sodium negative electrode is molten and in contact with the electrolyte membrane. Additionally, the cell is functional at an operating temperature between about 100° C. and about 170° C. Indeed, in some instances, the molten sodium secondary cell is functional between about 110° C. and about 130° C.

    摘要: The present invention provides a solid-state sodium-based secondary cell (or rechargeable battery). While the secondary cell can include any suitable component, in some cases, the secondary cell comprises a solid sodium metal negative electrode that is disposed in a non-aqueous negative electrolyte solution that includes an ionic liquid. Additionally, the cell comprises a positive electrode that is disposed in a positive electrolyte solution. In order to separate the negative electrode and the negative electrolyte solution from the positive electrolyte solution, the cell includes a sodium ion conductive electrolyte membrane. Because the cell's negative electrode is in a solid state as the cell functions, the cell may operate at room temperature. Additionally, where the negative electrolyte solution contains the ionic liquid, the ionic liquid may impede dendrite formation on the surface of the negative electrode as the cell is recharged and sodium ions are reduced onto the negative electrode.
