The polymer electrolytes are faced with poor conductivity and electrochemical stability despite their outstanding properties such as mechanical property, processability and improved safety. In this study, the gel polymer electrolyte containing porous-microcapsule was suggested to enhance an ionic conductivity. We synthesized porous-microcapsule and used as filler for PVdF-HFP gel polymer electrolyte system swollen with 1M LiClO4 in EC: DMC (3:7). From the results obtained, increasing the contents of porous-microcapsule up to 20wt%, the porosity of film was also increased and swelling ratio of film can be improved. It was closely related with an ionic conductivity, it was proven that the non-fillers PVdF-HFP gel polymer electrolyte system showed the conductivity value of 1.57Ⅹ10-3 S/cm and the ionic conductivity is further enhanced to 6.21Ⅹ10-3 S/cm with the addition of 20 wt% of porous-microcapsule. |
