  • Single ion conductor cross-linked polymeric networks
    Patent number: 7902299
    Abstract: Single ion conductors comprising polymer electrolytes prepared by grafting a salt compound onto a comb-branch polymer or dendrimer are disclosed having superior properties.
    Type: Grant
    Filed: September 19, 2005
    Date of Patent: March 8, 2011
    Assignee: The Regents of the University of California
    Inventors: John Borland Kerr, Shanger Wang, Jun Hou, Steven Edward Sloop, Yong Bong Han, Gao Liu
  • Polymeric electrolytes based on hydrosilyation reactions
    Patent number: 7101643
    Abstract: New polymer electrolytes were prepared by in situ cross-linking of allyl functional polymers based on hydrosilation reaction using a multifunctional silane cross-linker and an organoplatinum catalyst. The new cross-linked electrolytes are insoluble in organic solvent and show much better mechanical strength. In addition, the processability of the polymer electrolyte is maintained since the casting is finished well before the gel formation.

  • Sol-gel compositions and polymeric ion conductive film prepared therefrom
    Patent number: 6172152
    Abstract: The present invention provides a sol-gel composition which comprises a mixture of a polyalkylene glycol-substituted trialkoxysilane (PAGTAS), a polyalkylene glycol and/or alkyl ether, a tetraalkoxysilane (TAOS), a hydrochloric acid, at least one organic solvent and/or a lithium salt, which mixture is optionally concentrated; a polymeric ion conductive film obtained by coating said compositions with a conventional solution processing method and solid electrochemical elements using the same. According to the present invention, a polymeric ion conductive film having no phase separation, strong adhesiveness for electrode, and ion conductivity of at least 1×10−4 S/cm at room temperature is provided.
