  • Cathode materials for secondary (rechargeable) lithium batteries
    Publication number: 20070281215
    Abstract: The invention relates to materials for use as electrodes in an alkali-ion secondary (rechargeable) battery, particularly a lithium-ion battery. The invention provides transition-metal compounds having the ordered-olivine, a modified olivine, or the rhombohedral NASICON structure and the polyanion (PO4)3? as at least one constituent for use as electrode material for alkali-ion rechargeable batteries.
    Type: Application
    Filed: August 3, 2007
    Publication date: December 6, 2007
    Inventors: Michel Armand, John Goodenough, Akshaya Padhi, Kirakodu Nanjundaswamy, Christian Masquelier

  • Cathodes for rechargeable lithium-ion batteries
    Publication number: 20070082267
    Abstract: The present invention includes an apparatus and method of making and using a composition that includes the replacement of electrochemically inactive additives with a conductive and electrochemically active polymer that is attached so as to make an electrical contract to the redox couples of the electrochemically active oxide particles into/from which Lithium is reversibly inserted/extracted in a battery discharge/charge cycle.
