Composite Electrodes for Rechargeable Lithium-Ion Batteries

Technology available for licensing: Electrodes having composite xLi2M’O3·(1-x)LiMO2 structures in which an electrochemically inactive Li2M’O3 component is integrated with an electrochemically active LiMO2 component to provide improved structural and electrochemical stability.

  • Has superior cost features compared with current state-of-the-art LiCoO2 electrodes.
  • Offers high rate of charge/discharge and structural stability and prevents contamination of lithium layers by transition metal ions.
