Manju Mishra, S. N. Dixit, S. K. Tripathi . Studies on Nano Gel Polymer Electrolyte based Supercapacitors. National Conference on Role of Engineers in National Building. NCRENB2016, 4 (July 2016), 24-27.
In the present work, nano gel composite polymer electrolyte comprising of poly(vinylidine fluoride-co-hexafluropropylene) PVdF(HFP) - propylene carbonate (PC) - magnesium perchlorate Mg(ClO4)2- aluminium oxide (Al2O3) as an inert nano filler has been synthesized which exhibits ionic conductivity of 5. 9 x 10-3 S cm-1, showing good mechanical and dimensional stability which is suitable for their application in electrochemical devices like supercapacitors. The synthesized electrolyte material has been successfully checked in supercapacitors using activated charcoal as an electrode material. The electrochemical evaluation of EDLCs has been carried out by using a. c impedance spectroscopy techniques. The maximum capacitance of 153 mF cm-2 which is equivalent to single electrode specific capacitance of 44. 0 F g-1 achieved from the fabricated EDLCs.
