  • Electrochemical device having electrolyte including disiloxane
    Publication number: 20050170254
    Abstract: One example of the disiloxanes include a backbone with a first silicon and a second silicon. The first silicon is linked to a first substituent selected from a group consisting of: a first side chain that includes a cyclic carbonate moiety; a first side chain that includes a poly(alkylene oxide) moiety; and a first cross link links the disiloxane to a second siloxane and that includes a poly(alkylene oxide) moiety. In some instance, the second silicon is linked to a second substituent selected from a group consisting of: a second side chain that includes a cyclic carbonate moiety, and a second side chain that includes a poly(alkylene oxide) moiety.

  • Cross-linked polysiloxanes
    Patent number: 6887619
    Abstract: Disclosed herein are cross-linked polysiloxane polymers having oligooxyethylene side chains. Lithium salts of these polymers can be synthesized as a liquid and then caused to solidify in the presence of elevated temperatures to provide a solid electrolyte useful in lithium batteries.
    Type: Grant

    Assignee: Quallion LLC
    Inventors: Robert C. West, Zhengcheng Zhang
  • Electrolyte including polysiloxane with cyclic carbonate groups
    Publication number: 20040248014
    Abstract: The electrolyte includes a polysiloxane having one or more backbone silicons linked to a first side chain and one or more backbone silicons linked to a second side chain. The first side chains include a poly(alkylene oxide) moiety and the second side chains include a cyclic carbonate moiety. The electrolyte can be a liquid.
