  • High-energy cathode material particles with oxy-fluoride surfaces for aqueous processing
    Patent number: 11322748
    Abstract: A method of forming a metal oxy-fluoride surface on lithium metal oxide cathode material particles is disclosed. Such a metal oxy-fluoride surface may help to prevent lithium metal oxide cathode active materials from reacting with water, thus enabling aqueous processing of cathodes made from such materials in the manufacture of lithium batteries. Such a method may also reduce lithium battery manufacturing costs and time by substituting water for currently-used organic solvents that are expensive and require special handling and disposal. Such a method may also reduce the cost of lithium metal oxide cathode active materials as the requirements for moisture-free manufacture, storage, and processing will be reduced or eliminated.
    Type: Grant
    Filed: December 12, 2018
    Date of Patent: May 3, 2022
    Assignee: Robert Bosch GmbH
    Inventors: Lei Cheng, Saravanan Kuppan, Sondra Hellstrom, Michael Metzger, Yiqing Huang, Tristan Palmer, Hany Basam Eitouni
  • Fluorinated ionic liquids for multi-layer Li ion battery applications
    Patent number: 11258102
    Abstract: Fluorinated ionic liquids have been prepared to be used as catholytes in lithium battery cells. Such ionic liquids are immiscible with polyethylene-oxide-based solid polymer electrolytes, which may be used as separators in such cells. Such catholytes can increase the lifetime and boost the performance of lithium battery cells.
