  • Patent number: 8636916
    Abstract: A method of forming an electrolyte solution involves combining ammonium tetrafluoroborate and a quaternary ammonium halide in a liquid solvent to form a quaternary ammonium tetrafluoroborate and an ammonium halide. The ammonium halide precipitate is removed from the solvent to form an electrolyte solution. The reactants can be added step-wise to the solvent, and the method can include using a stoichiometric excess of the ammonium tetrafluoroborate to form a substantially halide ion-free electrolyte solution. Filtration can be done at low temperatures to reduce the amount of excess bromide in the resulting electrolyte.

    Abstract: This is to provide an electroconductive polymer material which has excellent adhesion to a base and excellent water resistance. Also, this is to provide a solid electrolytic capacitor which has excellent water resistance by using the same. An electroconductive polymer solution according to the present invention contains an electroconductive polymer, at least one water-soluble multivalent alcohol, and at least one oxoacid having two or more hydroxy groups. Since a resin obtained by carrying out a polycondensation reaction of the water-soluble multivalent alcohol and the oxoacid has a cross-linked structure, an electroconductive polymer having lower water-absorbing property and more excellent water resistance in comparison with a resin having a linear structure can be obtained.

  • Patent number: 8524399
    Abstract: Disclosed is a non-aqueous electrolyte including an electrolyte salt and an electrolyte solvent, the non-aqueous electrolyte further including a compound containing both a carboxy group and a (meth)acrylic group, and a secondary battery including the non-aqueous electrolyte. The use of the compound containing both the carboxy group and the (meth)acrylic group as a component for an electrolyte significantly reduces the increase of battery thickness at high temperature storage.

  • Publication number: 20130224606
    Abstract: The present invention directs to a non-aqueous electrolyte solution, including (I) at least one compound selected from the group consisting of fluorinated linear sulfones and fluorinated linear sulfonic acid esters, and (II) an electrolyte salt. Such a non-aqueous electrolyte solution has high oxidation resistance, minimizes its decomposition even when hydrofluoric acid is produced. Also, the solution is less likely to cause, in the case of being used for a secondary cell, swelling of the cell and lowering of the battery performance.
