The prime objective of the present article is to develop an efficient supercapacitor based on polymer electrolyte doped with salt. Solution cast technique was adopted to develop a solid polymer electrolyte of polymer poly(methyl methacrylate) (PMMA) as host polymer and salt potassium hydroxide (KOH) as a dopant. Incorporation of salt increases the amorphicity and assisted in conductivity enhancement. Moreover, doping of salt increases the overall conductivity of polymer electrolyte film. Electrochemical impedance spectroscopy reveals the enhancement in conductivity (four orders of magnitude) by salt doping. Fourier transform infrared shows the complexation and composite nature of films. Polarized optical microscopy shows the reduction in crystallinity, which is further confirmed by Differential scanning calorimetry. Fabricated electrochemical double-layer supercapacitor using maximum conducting polymer—salt electrolyte and symmetric carbon nanotubes electrodes shows specific capacitance of 21.86 F g−1.

The sole aim of the present article is to develop an ionic liquid (IL)-doped solid polymer electrolyte for an electrochemical double-layer capacitor (EDLC). A solution cast technique was adopted to develop a solid polymer electrolyte of poly (vinylidene fluoride-co-hexafluoropropylene) as host polymer and low-viscosity IL (1-ethyl-3-methylimidazolium thiocyanate) as dopant. Electrochemical impedance spectroscopy measurement showed a six orders of magnitude enhancement in conductivity ( σ) by IL doping. A linear sweep voltammetric investigation of the electrolyte films exhibited a good electrochemical stability window of 3.6 V. Polarized optical microscopy of the synthesized films revealed a reduction in crystallinity by IL doping. Infrared spectroscopy further affirms the composite nature of the film. The maximum conductivity value of 2.65 mS/cm is obtained for 80% of the ionic-doped system. Using maximum conductivity film and porous carbon-based electrodes, we have developed EDLCs that show a specific capacitance value of 2.36 F/g.

Solid polymer Electrolyte (SPE ) is prepared by using PEO as host polymer and AgCl as salt in appropriate wt% ratio of the composition [(1-X) PEO: x AgCl ] where X = 10, 20, 30, 40 etc.by novel hot press technique. For ion transport property study conductivity (s) measurement is done for various composition x in (wt %) and the composition [70 PEO: 30 AgCl] is identified as optimum conducting composition (OCC). The variation in conductivity as a function of temperature is analysed and activation energy (Ea) is computed be least square fitting of the data of conductivity with respect to temperature. The conductivity enhancement of more than one order is obtained in SPE (OCC) as compare to pure PEO. The morphological and structural characterization of SPE membrane is done by using XRD/DSC, SEM, and FTIR studies.

Polymer electrolyte membranes find application in a variety of fields such as battery systems, fuel cells, sensors and other electrochemical devices. In this paper we have done some investigations on the effect of chitin nanofiber (CNF) in PMMA based solid polymer electrolyte systems. CNF was synthesized from shrimp cell chitin by stepwise purification and acid hydrolysis method. PMMA basedelectrolyte films containing different concentrations of lithium salt and CNFs as filler were prepared by hot-press membrane technique. Crystalline nature and phase changes in polymer electrolytes were confirmed by X-ray diffraction analysis. Thermal behavior of the polymer electrolyte systems was studied by differential scanning calorimetry. Ionic conductivities of the electrolytes have been determined using a.c. impedance analysis in the temperature range between 303 and 393K. The temperature–dependent ionic conductivity
