Ionic liquid doped solid polymer electrolyte: Synthesis, characterization and applications ICSEM-2021

Abstract

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.

Current Scenario and Future Prospective of Ionic‐Liquid Doped Polymer Electrolyte for Energy Application

“…[66] For electrochemical device applications [67] such as fuel cells, high energy density rechargeable batteries, electrochromic displays, dye-sensitized solar cells (DSSC), supercapacitors, etc., polymer electrolytes are interesting materials. [68] A unique option in electrochemical devices [69] might be a polymer electrolyte with maximum conducting IL integrated with polymer electrolyte that is sandwitched between electrodes and utilized to construct electrical double layer capacitors (EDLC) [70] and dye-sensitive solar cells (DSSC). [71]…”

Insight into the use of ionic liquid-based polymer electrolyte for super capacitor application

“…Ionic liquids assumes the job which plasticizers performs (that increase the amorphous behavior and adaptability of the Solid Polymer Electrolytes) furthermore, it gives free ion transporters to conduction in Solid Polymer Electrolytes as reported in latest kind of literatures. [24][25][26][27] Not at all like inorganic salts which involve the use of a dissolvable for separation into cation and anion, ionic fluids don't require any dissolvable in separation and that completely made from separated natural cations and inorganic and or natural anions.…”

Environment-friendly approach for synthesis of promising porous carbon: empowering supercapacitors for a sustainable future

“…However, there is an urgent need to derive good-quality carbon from environmentfriendly sources. [3][4][5][6][7] Nowadays, various studies have endeavored to synthesize high volumes of PC from waste materials, [8][9][10] polyvinyl chloride, [11][12][13] corn starch, 14 orange-apple peels, 15 etc. These sources offer a cheap and environmentally friendly path to obtaining good quality electrode materials.…”
