Device and Method for Fluidizing and Coating of Ultrafine Particles

Technology available for licensing: An ultrathin surface coating composed of metal oxides that, when applied to granular electrode materials on a large scale, promises to solve the structural instability of electrode materials and the resulting rapid fade of cell capacity at high voltages and high temperatures in lithium-ion batteries

  • A low-cost, scalable process for increasing structural stability and cell capacity of battery electrodes
  • Creates an ultra-thin film that allows lithium ions and electrons to easily tunnel without a large increase in impedance
