PAN-based ge l po lym er electro lytes supercapacitors w ere also fabricated. The behaviors of GPE s w ere m easured by A C mi pedance. The properties of PAN based GPEs capacito rsw ere studied by mi pedance spectrum, cyclic vo ltamm etry, constant current charge / discharge. Im pedance spectra w ere analysed by smi ulat ing equivalent circu it. The resu lt showed that the con- - 1 duct iv it ies o f the PAN-based gel polym er electro ly tes can be as h igh as 7. 54mS cm at am bient tem perature. W ith actived carbon e lectrodes, the w ork ing vo ltage o f the supercapac itors can be as h igh as 2. 5V. The internal resistance 2 of the capac itorsw ere ju st 8. 92- 12. 6 cm .
