  • Patent number: 10673064
    Abstract: Performance of a thermal lithium battery is improved by improving the ion-transport characteristics of a solid lithium iodide electrolyte. The lithium iodide lattice of the solid electrolyte includes defects that improve the ion-transport characteristics of the solid lithium iodide electrolyte. In one example, the defects are due to the introduction of nanoparticles that result in grain boundary defects. The defects resulting at the grain boundaries with the nanoparticles improve the ion transport characteristics of the electrolyte. In another example, defects originating from the synthesis process are pinned by the presence of nanoparticles and/or the reinforcing structure. In another example, the defects are aliovalent substitution defects. A cation that is aliovalent to the lithium cation (Li+), such as a barium cation (Ba2+), creates an aliovalent substitution defect in the lithium iodide lattice.

    Abstract: A hybrid battery with a sodium anode is designed for use at a range of temperatures where the sodium is solid and where the sodium is molten. When the battery is at colder temperatures or when the vehicle is idle and needs to be “started,” the anode will be solid sodium metal. At the same time, the battery is designed such that, once the electric vehicle has been “started” and operated for a short period of time, heat is directed to the battery to melt the solid sodium anode into a molten form. In other words, the hybrid battery operates under temperature conditions where the sodium is solid and under temperature conditions where the sodium is molten.

Embodiments of the invention provide a wicking component, a current collector, and a bias component. The current collector is positioned to force the bias component to press the wicking component tight to an inner surface of a separator. The bias component maintains contact between the wicking component and the surface of separator and creates a capillary gap in which sodium wicks.

  • Patent number: 9000713
    Abstract: Electrochemical cells having molten electrodes having an alkali metal provide receipt and delivery of power by transporting atoms of the alkali metal between electrode environments of disparate chemical potentials through an electrochemical pathway comprising a salt of the alkali metal. The chemical potential of the alkali metal is decreased when combined with one or more non-alkali metals, thus producing a voltage between an electrode comprising the molten the alkali metal and the electrode comprising the combined alkali/non-alkali metals.

  • Patent number: 8974939
    Abstract: An electrochemical device (such as a battery) includes at least one electrode having a fluid surface, which may employ a surface energy effect to maintain a position of the fluid surface and/or to modulate flow within the fluid. Fluid-directing structures may also modulate flow or retain fluid in a predetermined pattern. An electrolyte within the device may also include an ion-transport fluid, for example infiltrated into a porous solid support.

  • Publication number: 20150030896
    Abstract: A sodium-halogen secondary cell that includes a negative electrode compartment housing a negative, sodium-based electrode and a positive electrode compartment housing a current collector disposed in a liquid positive electrode solution. The liquid positive electrode solution includes a halogen and/or a halide. The cell includes a sodium ion conductive electrolyte membrane that separates the negative electrode from the liquid positive electrode solution. Although in some cases, the negative sodium-based electrode is molten during cell operation, in other cases, the negative electrode includes a sodium electrode or a sodium intercalation carbon electrode that is solid during operation.

  • Publication number: 20140363717
    Abstract: An additive that is added to the NaAlX4 electrolyte for use in a ZEBRA battery (or other similar battery). This additive has a moiety with a partial positive charge (?+) that attracts the negative charge of the [AlX4]? moiety and weakens the ionic bond between the Na+ and [AlX4]? moieties, thereby freeing some Na+ ions to transport (move). By using a suitable NaAlX4 electrolyte additive, the battery may be operated at much lower temperatures than are typical of ZEBRA batteries (such as, for example, at temperatures between 150 and 200° C.). Additionally, the additive also lowers the viscosity of the electrolyte solution and improves sodium conductivity. Non-limiting examples of the additive SOCl2, SO2, dimethyl sulfoxide (DMSO, CH3SOCH3), CH3S(O)Cl, SO2Cl2. A further advantage of using this additive is that it allows the use of a NaSICON membrane in a ZEBRA-type battery at lower temperatures compared to a typical ZEBRA battery.

  • Publication number: 20140356681
    Abstract: A brazing structure for an electrochemical cell is described. It includes a nickel or nickel alloy component; a ceramic component; a braze alloy layer, containing an active metal element, between the nickel and the ceramic component, and a barrier layer disposed between the nickel layer and the braze alloy layer. The barrier layer is capable of preventing or minimizing the diffusion of the active metal element into the nickel or nickel alloy component. Electrochemical cells that include such a brazing structure are also described, as are related methods for joining nickel components to ceramic components in the manufacture of thermal batteries.

  • Publication number: 20140356654
    Abstract: A hybrid battery with a sodium anode is designed for use at a range of temperatures where the sodium is solid and where the sodium is molten. When the battery is at colder temperatures or when the vehicle is idle and needs to be “started,” the anode will be solid sodium metal. At the same time, the battery is designed such that, once the electric vehicle has been “started” and operated for a short period of time, heat is directed to the battery to melt the solid sodium anode into a molten form. In other words, the hybrid battery operates under temperature conditions where the sodium is solid and under temperature conditions where the sodium is molten.
