  • Electric energy storage device and method for manufacturing the same
    Patent number: 6726732
    Abstract: An electric energy storage device includes a first electrode, a gel type ionic conducting polymer electrolyte separator formed on the first electrode, and a second electrode corresponding to the first electrode. The energy storage device has an increased unit storage capacitance and more minimized size by using the gel type ionic conducting polymer electrolyte separator. Also, the energy storage device produces a reduced resistance by the gel type ionic conducting polymer electrolyte separator, such that the high frequency response characteristic is improved, the available frequency region is enlarged and the allowable ripple current is increased.
    Type: Grant
