  • Patent number: 8852785
    Abstract: A bipolar secondary battery has a battery element that includes first and second bipolar electrodes each having a collector disposed with a conductive resin layer containing a first resin as a base material and positive and negative electrode active material layers formed on opposite sides of the collector and a separator containing a second resin as a base material, arranged between the first and second bipolar electrodes and retaining an electrolyte material to form an electrolyte layer. The positive electrode active material layer of the first bipolar electrode, the electrolyte layer and the negative electrode active material layer of the second bipolar electrode constitute a unit cell. A melting point of the first resin is lower than or equal to a melting point of the second resin. Outer peripheries of the collectors of the first and second bipolar electrodes and an outer periphery of the separator are fused together to thereby seal an outer peripheral portion of the unit cell.

  • Patent number: 8765275
    Abstract: An energy storage device is provided that includes a separator having a first surface and a second surface. The first surface defines at least a portion of a cathodic chamber, and the second surface defines an anodic chamber. The cathodic chamber includes an alkali metal halide that forms an ion that is capable of conducting through the separator. The anodic chamber has a volume that is filled with a consumable fluid. The amount of the consumable fluid is greater than 90 percent by volume of the anodic chamber volume. Furthermore, the consumable fluid is reactive with an ionic species of the alkali metal halide. A method of sealing the energy storage device is also provided.

  • Publication number: 20140162108
    Abstract: Protected anode architectures provide a hermetic enclosure for an active metal (e.g., alkali metal, such as lithium) anode inside an anode compartment. The compartment is substantially impervious to ambient moisture and battery components such as catholyte (electrolyte about the cathode, and in some aspects catholyte may also comprise dissolved or suspended redox active species and redox active liquids), and prevents volatile components of the protected anode, such as anolyte (electrolyte about the anode), from escaping, while allowing for active metal ion transport between the anode and cathode into and out of the anode compartment.
