  • Cathode materials for secondary (rechargeable) lithium batteries
    Patent number: 8282691
    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 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: Grant
    Filed: October 7, 2011
    Date of Patent: October 9, 2012
    Assignee: Hydro-Quebec
    Inventors: John B. Goodenough, Akshaya K. Padhi, Kirakoda S. Nanjundaswamy, Christian Masquelier
