  • Patent number: 10658698
    Abstract: Syntheses of graft copolymers based on PEO and fluorinated functional groups are described. Grafting of fluorinated groups reduces the Tm of PEO and also increases the miscibility of PEO with ionic liquids, so that addition of ionic liquids improves ionic conductivity even at room temperature. The disclosed copolymers containing fluorinated functionality have superior safety and are more flame retardant as compared to traditional electrolytes. Such copolymers can be used as either solid or gel electrolytes in Li batteries.

  • Patent number: 10622672
    Abstract: Composites of lithium-ion-conducting ceramic and polymeric materials make superior separators and electrolytes for use in lithium batteries. The ceramic material provides a high conductivity pathway for lithium-ions, enhancing the properties of the less conductive polymeric material. The polymeric material provides flexibility, binding, and space-filling properties, mitigating the tendency of rigid ceramic materials to break or delaminate. The interface between the polymer and ceramic can be made to have a low ionic resistance through the use of additives and coatings.

  • Publication number: 20200106105
    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.

  • Publication number: 20200102451
    Abstract: New polymer compositions based on poly(2,6-dimethyl-1,4-phenylene oxide) and other high-softening-temperature polymers are disclosed. These materials have a microphase domain structure that has an ionically-conductive phase and a phase with good mechanical strength and a high softening temperature. In some arrangements, the structural block has a softening temperature of about 210° C. These materials can be made with either homopolymers or with block copolymers. When these polymers are combined with electrolyte salts, they can be used as electrolytes that have both high ionic conductivity and good mechanical properties.

  • Publication number: 20190280292
    Abstract: Commercially-available lithium metal foils have been found to have a high density of crystalline defects. When such foils are used as the anode in a secondary lithium metal battery cell, repeated cycling may lead to the formation of lithium shunts near the crystalline defects, which can cause shorting. Methods described herein may be used to reduce the density of crystalline defects in lithium metal foils. Such lithium metal can be used as the anode in lithium battery cells.
