  • Patent number: 8895193
    Abstract: A solid ionic electrolyte having an organic plastic crystal solvent (e.g. succinonitrile) doped with lithium bioxalato borate salt (LiBOB) may be used in an electrochemical device. Electrochemical devices are disclosed having a cathode, an anode, and a solid ionic electrolyte having a neutral organic plastic crystal solvent doped with LiBOB alone or in combination with another lithium salt. Such devices have a stable electrolyte interface over a broad potential window combined with high energy density delivery capacity and, in one example, the favorable properties of a neutral organic plastic crystal matrix such as succinonitrile.

  • Publication number: 20140335425
    Abstract: A polymer that provides for effective proton/cation transfer within, through, across the polymer. The polymer may be used in an electrochemical sensor and may include a redox active species and a facilitator of proton transfer that may provide for the “shuttling”/transfer of a proton through the polymer. As such, the polymer may provide for protons to be transferred through the polymer from or to a conducting substrate. The polymer may also provide for separation of components, fluids, materials in an electrochemical system while still allowing for a transfer, shuttling of protons or cations between the components, fluids or material. The proton, cation transfer polymer may be used in a battery, an electrochemical sensor or a fuel cell.

  • Publication number: 20140322614
    Abstract: A sulfur-based cathode for use in an electrochemical cell is disclosed. The sulfur is sequestered to the cathode to enhance cycle lifetime for the cathode and the cell. An exemplary sulfur-based cathode is coupled with a solid polymer electrolyte instead of a conventional liquid electrolyte. The dry, solid polymer electrolyte further acts as a diffusion barrier for the sulfur. Together with a sequestering matrix in the cathode, the solid polymer electrolyte prevents sulfur capacity fade that occurs in conventional liquid electrolyte based sulfur systems. The sequestering polymer in the cathode further binds the sulfur-containing active particles, preventing sulfur agglomerates from forming, while still allowing lithium ions to be transported between the anode and cathode.

  • 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.
