  • Patent number: 8852815
    Abstract: A solid electrolyte for an electrochemical device includes a composite of a plastic crystal matrix electrolyte doped with an ionic salt and a crosslinked polymer structure having a linear polymer as a side chain chemically bonded thereto. The linear polymer has a weight average molecular weight of 100 to 5,000 and one functional group. The electrolyte has high ionic conductivity comparable to that of a liquid electrolyte due to the use of the plastic crystal, and high mechanical strength comparable to that of a solid electrolyte due to the introduction of the crosslinked polymer structure. A method for preparing the solid electrolyte does not essentially require the use of a solvent, eliminating the need for drying. The electrolyte is suitable for use in a cable-type battery whose shape is easy to change due to its high ionic conductivity and high mechanical strength comparable to that of a solid electrolyte.

  • Patent number: 8835076
    Abstract: In a fuel cell 1 including a membrane electrode assembly 2 which includes a reinforcing-membrane-type electrolyte membrane 10A, a dry-up on the anode side is suppressed by actively forming a water content gradient in the electrolyte membrane to enhance water back-diffusion effect from the cathode side to the anode side. For that purpose, two sheets of expanded porous membranes 12a and 12b having different porosities are buried, as reinforcing membranes, in electrolyte resin 11 to obtain the reinforcing-membrane-type electrolyte membrane 10A. The reinforcing-membrane-type electrolyte membrane 10A is used to form the membrane electrode assembly 2, which is sandwiched by separators 20 and 30 such that the side of a reinforcing membrane 12b with a larger porosity becomes the cathode side, thus obtaining the fuel cell 1. When one sheet of the reinforcing membrane is buried, the reinforcing membrane is offset to the anode side to be buried in the electrolyte resin.

  • Patent number: 8691444
    Abstract: Protected anode architectures for active metal anodes have a polymer adhesive seal that provides a 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 a hermetic seal at the joint between a surface of the protected anode and the container.
