  • Patent number: 8652673
    Abstract: A solid electrolyte layer and electrode layers are formed within an electrically insulating frame part, and current collecting plates are held by the electrically insulating frame part. Since the current collecting plates are held by the frame part, the shifting or coming-apart of the current collecting plates can be restrained. In order to cause the current collecting plates to be held by the frame part, a powder of material of the electrode layer is filled in between the frame part and the current collecting plates.

  • Patent number: 8445134
    Abstract: An electrochemical cell for a secondary battery is provided, which includes a positive electrode having an intercalation cathode material of bentonite; a negative electrode material having an anode material containing one of magnesium and sodium; an electrolyte positioned in contact with at least one of the positive electrode and the negative electrode; wherein, when the anode material contains magnesium, the electrolyte is a solid gel polymeric electrolyte; and wherein, when the anode material is sodium, the electrolyte is a salt electrolyte, both the anode material and the electrolyte are molten at the operating temperature of the battery, and the cell further comprises a beta alumina solid electrolyte separator between the negative electrode and the electrolyte. To increase its conductivity, the bentonite material is treated, before cell assembly, with an acid and/or intercalated with an anilinium ion, which is then polymerized to form a polyaniline within the bentonite framework.

  • Patent number: 8445139
    Abstract: The disclosure relates to bipolar cells including electrodes surrounding a collector. Embodiments of the bipolar cells include a collector containing a high-polymer material. The disclosure also relates to bipolar electrode batteries containing bipolar cells including a collector body containing electrically conductive high-polymer or electrically conductive particles distributed in a high-polymer. By adding such high molecular weight polymer material to the collector, the weight of the collector may be reduced and the output power density per weight of the battery may be improved. The disclosure further relates to methods of forming collecting bodies and electrodes for bipolar cells using an inkjet printing method. Bipolar cells according to the present invention may be used to fabricate batteries such as lithium ion batteries, which may be connected to form battery modules used, for example, to provide electrical power for a motor vehicle.

  • Patent number: 8445136
    Abstract: Protected anode architectures for active metal anodes have a polymer adhesive seal that provides an hermetic enclosure for the active metal of the protected anode inside an anode compartment. The compartment is substantially impervious to ambient moisture and battery components such as catholyte (electrolyte about the cathode), and prevents volatile components of the protected anode, such as anolyte (electrolyte about the anode), from escaping. The architecture is formed by joining the protected anode to an anode container. The polymer adhesive seals provide an hermetic seal at the joint between a surface of the protected anode and the container.
