  • Patent number: 7011908
    Abstract: The present invention provides a manganese bismuth mixed metal oxide cathode material through a solid-state reaction between manganese dioxide, and either bismuth or a bismuth compound in a compound having the general formula MnOy(Bi2O3)x, which affords charge transfer catalytic behavior that allows the cathode to be fully reversible at suppressed charge potentials and increased discharge potentials. The MnOy(Bi2O3)x cathode material may be incorporated into an electrochemical cell with either a lithium metal or lithium ion anode and an organic electrolyte. The present invention provides a compound with the general formula MnOy(Bi2O3)x, where subscript x is between 0.05 and 0.25, subscript y is about 2 and the overcharge protection is not needed as the subscript z approaches 0.0. In the preferred embodiment, a cathode material where subscript x is between 0.05 and 0.135 with the formula MnO2(Bi2O3)0.12 provides the much-needed full reversibility, high voltage stability and reduced charge transfer impedance.

  • Patent number: 6856840
    Abstract: An ionically conductive polymeric composition is disclosed. The composition is especially useful for coating an implantable hot can defibrillator electrode. The polymeric composition, for example, polyethylene oxide containing NaCl or a similar ionic medium, can be used to coat and fill the pores of a high surface area electrode to provide a continuous ionic network from the can to the adjacent body tissue. The conductive polymeric composition is biocompatible, chemically and mechanically stable and does not dissolve or leach out over the useful lifetime of the defibrillator. A hot can defibrillator employing the polymeric coating avoids development of high polarization at the can/tissue interface and maintains a more uniform defibrillation threshold than conventional implantable defibrillators, thus increasing the feasibility of pectoral implantation, particularly in a “dry pocket” environment.

  • Patent number: 6833089
    Abstract: A surface of a glass plate is coated with a first n-type semiconductor film which is a 50 nm-thick niobium oxide film as a primer layer. The primer layer is coated with a 250 nm-thick photocatalyst film comprising titanium oxide. Thus, an article having a photocatalytically active surface is obtained. The two coating films can be formed by sputtering. The first n-type semiconductor film as the primer layer is selected so as to have a larger energy band gap than the titanium oxide. Due to this constitution, more holes are generated near the film surface. This article can be free from the problem of conventional titanium oxide films having photocatalytic activity that it is difficult to generate many surface holes contributing to photocatalytic activity, because electrons and holes generated by charge separation recombine within the film, making it impossible to effectively heighten catalytic activity.
