    Abstract: A battery cathode comprises an electrode of silver, molybdenum, oxygen, fluorine and chlorine and having a higher discharge capacity expressed as milliampere hour per gram of material (mAh/g) available from silver reduction at a potential above 3V as compared to that of SVO material versus lithium. The battery cathode compound can be represented by Ag6 Mo2O7F3Cl. The cathode is devoted for primary lithium batteries application and most notably can be used in a medical battery, such as a defibrillator battery [e.g. implantable cardioverter defibrillator (ICD) battery] having a lithium metal anode.

    Abstract: Supercapacitor cell electrode and separator elements formulated as membranes of plasticized polymers matrix compositions are laminated with electrically conductive current collector elements to form flexible, unitary supercapacitor structures. The matrix plasticizer component is extracted from the laminate with polymer-inert solvent and replaced with electrolyte solution to activate the supercapacitor. Various arrangements of cell structure elements provide parallel and series cell structures which yield improved specific energy capacity and increased voltage output for utilization demands. The supercapacitor elements may also be laminated with similar polymeric rechargeable battery cell structures to provide hybrid devices capable of delivering both high energy and high power as needed in electronic systems.

    Abstract: An apparatus and method for monitoring structural changes of an electrode in a rechargeable battery include an in situ x-ray study electrochemical cell holder (30) comprising top and bottom cell holder members (32, 34) including at least one beryllium window element (36) for transmission of diffractometer x-radiation. A rechargeable battery cell (43) mounted within the x-ray cell holder enclosure comprises an electrolyte/separator element (68) interposed between positive and negative electrodes (64, 66). A current collector element (70) formed of an electrically-conductive open-mesh grid is disposed between the positive electrode and the separator to enable ion-conducting contact of the electrode and separator while maintaining electrical continuity between the electrode and an external x-ray cell holder terminal (54). As a result of this arrangement, the positive electrode need not contact the window element to establish an electrical battery circuit, but may be sufficiently spaced from the window to avoid electrolytic corrosion of the beryllium element. The in situ x-ray electrochemical cell holder and battery cell structure allow for continuous monitoring of the structural changes in electrode materials during charge/discharge cycling.

    Abstract: Irreversible loss of lithium during the initial discharge cycle of secondary batteries with carbon intercalation electrodes is substantially reduced by employing as the cell electrolyte a non-aqueous solution of LiPF.sub.6 in a mixture of dimethylcarbonate and ethylene carbonate. By this means, in a secondary battery cell comprising, for example, a Li.sub.1+x Mn.sub.2 O.sub.4 positive electrode and a graphite negative electrode, up to about 90% of the theoretical level of lithium can be reversibly cycled at an exceptionally high rate of about C/1 (complete discharge in one hour).

    Abstract: A flexible polymeric film useful as an interelectrode separator or electrolyte member in electrolytic devices, such as rechargeable batteries, comprises a copolymer of vinylidene fluoride with 8 to 25% hexafluoropropylene. The film may be cast or formed as a self-supporting layer retaining about 20% to 70% of a high-boiling solvent or solvent mixture comprising such solvents as ethylene carbonate, propylene carbonate, dimethyl carbonate, and dibutyl phthalate. The film may be used in such form or after leaching of the retained solvent with a film-inert low-boiling solvent to provide a separator member into which a solution of electrolytic salt is subsequently imbibed to displace retained solvent or replace solvent previously leached from the polymeric matrix.
