Abstract :
Quasi-solid-state carbon supercapacitors offering high power density, flexibility and long cycle life have shown excellent potential for commercial applications. A brief overview of the IL based gel/polymer electrolytes has been presented. Some recent findings of the present laboratory on the ionic liquid incorporated polymer electrolytes based solid state electrical double layer capacitors (supercapacitors) are discussed. From the comparative studies, it has been concluded that PVdF-HFP based gel electrolytes perform better than the PEO based electrolytes. The non polar nature of the PVDF-HFP gels provides structural integrity, while at the same time allowing for the formation of high ionically conductive channels, offering their suitability as electrolytes in supercapacitors.

Keywords : ionic liquid, PEO based electrolytes.
