A spinel-type lithium-containing metallic oxide represented by LiM.sub.2 O.sub.4 (where M is a transitional metal element) is used as an active substance for each of the positive and negative electrodes of the cell embodying the invention. In an organic electrolyte containing lithium ion, the spinel-type lithium-containing metallic oxide represented by LiM.sub.2 O.sub.4 is capable of reversibly undergoing an electrochemical oxidation reaction involving removal of doping lithium ion and also an electrochemical reduction reaction involving lithium ion doping. Accordingly, when the cell of the invention is overdischarged (.apprxeq.Type: GrantFiled: April 20, 1995Date of Patent: January 7, 1997Assignee: Hival Ltd.Inventor: Toru Nagaura

Patent number: 5447808Abstract: A battery of high temperature cells in a battery casing includes a plurality of rigid metal elements secured to a rigid board of electrical insulating material. The metal elements provide mutually insulated conducting pathways. One end of each of the metal elements connects to either a cell or a bank of cells and an opposite end converges to a location on the board. The board may include one or more of these locations to allow for multiple electrical connections to be made through the casing. In addition, the number of the locations on the board may be less than the number of metal elements.Type: GrantFiled: November 8, 1993Date of Patent: September 5, 1995Assignee: Chloride Silent Power LimitedInventor: John Molyneux

Patent number: 5436089Abstract: A battery pack is provided for housing a plurality of fiat cells for portable electronic device applications. The battery pack is sufficiently thin to preserve the desirable thin profile of the fiat cells and yet exhibits surprising structural integrity considering the relatively thin polycarbonate material from which the housing of the pack is fabricated. A plurality of thin cells is laterally arranged side by side in spaced-apart relationship to form a cell subassembly. An adhesive is applied to a polycarbonate sheet. The sheet is then cut to a predetermined form and embossed to form creases along predetermined fold lines. The prepared sheet is then folded at the fold lines and positioned to substantially surround the cell subassembly and form a box-like structure around such subassembly. Adhesive on an upper sheet section adheres to the top planar surfaces of the fiat cells while adhesive on a lower sheet section adheres to the bottom planar surfaces of the flat cells.Type: GrantFiled: August 31, 1993Date of Patent: July 25, 1995Assignee: VST Power Systems, Inc.Inventor: Vincent Fedele

Patent number: 5330857Abstract: High-purity nitrogen gas is generated by reducing at least the residual oxygen content of at least the cathode exhaust gas stream of a fuel cell device. The oxygen reduction is achieved either by controlling the passage of an oxidant gas through the cathode side of the fuel cell device in such a manner as to increase the oxygen utilization at the cathode side of the fuel cell device relative to the optimum electric power generation operating conditions of the fuel cell device, or by removing most of the residual oxygen from the cathode exhaust gas stream exhausted from the cathode side of the fuel cell device, while maintaining both oxygen and nitrogen contained in the cathode exhaust gas in their gaseous states throughout, or both. Moreover, anode exhaust gas can be reacted in a reformer burner with a reduced amount of excess oxygen and/or the reformer burner exhaust gas can be purified to remove combustion products and/or oxygen therefrom.Type: GrantFiled: September 22, 1993Date of Patent: July 19, 1994Assignee: International Fuel Cells CorporationInventors: Richard A.
