| Abstract: | Recent advances in the study of ionic
liquids based gel polymer electrolytes have been briefly reviewed in view of
their electrochemical applications, particularly, their application as electrolytes
in supercapacitors. The incorporation of ionic liquids in gel polymer
electrolytes, instead of organic solvents like propylene carbonate, ethylene
carbonate, etc., provide added effect in terms of their thermal, electrical and
electrochemical stabilities. Recent studies on poly(ethylene oxide) based
polymer electrolyte plasticized with ionic liquid and ionic liquid incorporated
poly(vinylidene fluoride-
co-hexafluoropropylene) based gel polymer electrolytes have been summarized. A
special description has been given of supercapacitors (electrical double layer
capacitors), studied in our laboratory, based on multiwalled carbon nanotubes,
activated charcoal powder electrodes and optimized gel/polymer electrolytes.
Comparative studies indicate that PVdF-HFP based gels are superior electrolytes
to develop electrical double layers capacitors (in terms of higher capacitances
and lower resistive values) over PEO based plasticized polymer electrolytes. |
