Ionic liquid incorporated polyvinylpyrrolidone (PVP) doped with ammonium iodide (NH4I) doped solid polymer electrolyte for energy device

In this paper, we have used polymer polyethylene oxide as a host matrix and novel electrolyte ionic liquid 1-ethyl-3-methylimidazolium tricyanomethanide as an dopant to increase ionic mobility. Different characterization techniques like Electrochemical impedance spectroscopy, dielectric measurement, Fourier transform, X-ray diffraction, polarized optical microscopy, thermogravinometric analysis were used to identify the electrical, optical, structural and thermal properties. A laboratory scale supercapacitor has been fabricated using optimized solid polymer electrolyte film as an electrolyte and porous carbon derived from corn starch which shows a specific capacitance 13.6 F/g at 50 mV/s scan rate.

“…In the solid polymer electrolyte film which was developed via solution cast technique using 1-ethyl-3-methylimidazolium tricyanomethanide incorporated in PVP and NH 4 I complex, the conductivity was found to be increased to 4.0*10 À4 S/ cm when an IL ranged from 0 to 4 wt% in the complex. The supercapacitor developed from the film showed a specific capacitance of 15.8 F/g at scan rate 20 mV/s in a voltage range 0-1 V. 150 The various supercapacitors fabricated with electrodes/electrolytes are incorporated in Table 3.…”

Ionic liquid (IL) is now being considered as a novel contender in the development of highly conducting polymer electrolytes rather than a solvent. It has a significant impact on the electrochemical performance of polymer electrolytes. This study emphasizes the significance of low viscosity IL dispersion within a polymer (PVA) matrix. The electrical, structural and photoelectrochemical properties of the IL-doped polymer electrolyte are discussed in detail. These highly conducting IL doped solid polymer electrolytes show promise towards the development of highly efficient Supercapacitors.

“…They have many properties like high molecular weight, they usually behave like solids, but do display unique features like visco-elasticity and toughness, great flexibility, and durability in processing and practical use, thus they have wide range of usage. Polymer-based electrolytes [7][8][9][10][11] are the solid polymeric membranes which can be used as ion conductors by adding suitable salts, acids and ionic liquids. The EDLC fabricated with the nanofillerincorporated PVdF-HFP electrolyte films performs better in terms of specific capacitance, energy and power 12 Due to their good ion transport properties, they find their applications in energy devices like supercapacitors, organic solar cells, fuel cell and batteries.…”

We have successfully synthesized highly conducting polymer electrolyte incorporated ionic liquid films. There was a rise in conductivity by ionic liquid doping which is clarified by impedance spectroscopy. Fourier transform infra red spectroscopy confirms complexation as well as composite nature. Polarized optical microscopy shows decrease in crysatllinity (more amorphous) by ionic liquid doping. Maximum conducting ionic liquid incorporated polymer electrolyte sandwitched between electrodes, used for fabricating electrical double layer capacitor (EDLC) and dye sensitized solar cell (DSSC) further affirm that these ionic liquid doped polymer electrolyte could be a novel alternative in electrochemical devices.
