  • Electric double layer capacitor and method for producing the same
    Publication number: 20030007316
    Abstract: The present invention provides a method for producing an electric double layer capacitor mountable by reflow soldering, which comprises assembling an electric double layer capacitor, subjecting the capacitor to a heat treatment following a temperature profile resembling to the temperature profile with respect to time employed in the reflow soldering step, and welding a terminal thereafter.

  • Electrical double layer capacitor and portable electronic apparatus equipped with electrical double layer capacitor
    Patent number: 6459564
    Abstract: An electrical double layer capacitor has an electrolyte comprised of a non-aqueous solvent and a supporting salt dissolved in the non-aqueous solvent. A pair of polarizing electrodes are disposed in confronting relation with one another. A separator is disposed between the polarizing electrodes. The supporting salt contained in the electrolyte exists only in regions proximate a surface of the polarizing electrodes when the electrical double layer capacitor is fully charged. The non-aqueous solvent contains a preselected amount of dissolved supporting salt calculated from a surface area of the polarizing electrodes and a size of a molecule of the supporting salt in an ionized state.

  • Non-aqueous electrolyte secondary battery with a lithium copper titanium oxide electrode
    Patent number: 6395425
    Abstract: Provided is a non-aqueous electrolyte secondary battery capable of ensuring good characteristics even in case of low-voltage charge at 2.5 V or so. A composite oxide of a compositional formula, LiaCubTicO4 (with 0<a≦1, 0<b≦0.5, 1.5≦c<2) serving as a positive or negative electrode active material is mixed with an electroconductive agent and a binder, and shaped under pressure into electrodes for the battery.
