EXAMPLE - Poly(vinylidene fluoride) (PVdF) (1.5 g) (Kynar 761 (TM)) dried for at least 24 hours at 80 degrees C, polyethylene glycoldiacrylate (PEGDA) (Aldrich molecular weight 742) (1 g) as a UV curing agent, and a liquid electrolyte (10 g) including ethylene carbonate (EC)/diethylene carbonate (DEC) of 1:1 weight ratio and 1M of LiPF6 were agitated uniformly for 2 hours by 300 rpm at room temperature, 2-chlorobenzophenone (0.1 g) (molecular weight 216.67) was added as an initiator and the temperature increased to 125 degreesC. Mixing was then carried out for 30 minutes to make the mixed solution transparent. The above-formed gel type polymer electrolyte was coated 40 50 microns thick on a non-woven fabric preheated at 80 degrees C, or cast by the Doctor Blade method, UV ray irradiation was then carried out for 1 hour by leaving a distance of 10-15 cm from a 100W UV-ray lamp just to induce polymerization of oligomer. An uniform gel type polymer electrolyte was attained. An electric double-layered capacitor including active carbon electrode having 2000 m2/g of specific surface area/gel type polymer electrolyte prepared by the present invention/active electrode was checked by carrying out charge/discharge of electricity in a manner that the electric double layered capacitor was charged with 2.5V of constant voltage and discharges 2 mA/cm2 of constant current.
