Preliminary Study

Abstract Redox capacitor, which is one type of supercapacitor, has been attracted tremendously as they show a satisfactory specific capacitance, good cycle ability, and good stability. The present study reveals a redox capacitor fabricated with an ionic liquid (IL) based gel polymer electrolyte (GPE). Electrodes of the redox capacitor were fabricated with the conducting polymer, polypyrrole (PPy). The composition of the GPE was polyvinylidenefluoride-co-hexafluoropropylene (PVdF-co-HFP) : 1-ethyl-3-methylimidazolium trifluoromethanesulfonate (1E3MITF) : ZnTF. Characterization of redox capacitor was done by electrochemical impedance spectroscopy (EIS), cyclic voltammetry (CV), and galvanostatic charge-discharge (GCD) tests. The relaxation time constant (τ0) of the redox capacitor is about 31.57 s implying somewhat fast redox reactions. Initial single electrode specific capacitance (CSC) was 150.16 Fg-1 and at the 500th cycle, it was 40.03 Fg-1. The decrease of the CSC may be due to the formation of the passivation layer at the GPE / electrode interface resulting in degradation upon cycling. The GCD test resulted 48.40 Fg-1 of initial single electrode specific discharge capacitance (Csd) value. Upon 1000 cycles, it was reached 22.25 Fg-1. The decrease of Csd may be due to the degradation of the electrode and the IL-based GPE upon prolonged cycling.

Electrolyte as one of the major components in dye sensitized solar cells (DSSCs) plays an important role in dye regeneration and as the inner charge carrier transport between electrodes. Gel polymer electrolyte is a potential alternative to liquid electrolytes which suffer of leakage and solvent evaporation. In this present research, functionalization of chitosan by the quaternization reaction of chitosan with iodopropane forming tripropyl chitosan iodide is proposed for the preparation of gel polymer electrolyte. Tripropyl chitosan iodide was characterized by nuclear magnetic resonance spectroscopy (NMR), Fourier transform infrared spectroscopy (FTIR) and thermogravimetric analysis (TGA). Four different polymer electrolytes were tested at different compositions in presence of iodide/triiodide redox salt and imidazolium ionic liquid in DSSCs configurations. The results show that the gel polymer electrolyte containing the tripropyl chitosan iodide in presence of 1-propyl-3-methylimidazolium iodide ionic liquid showed better performance with power conversion efficiency of 0.415% as compared to the gel polymer electrolyte film without ionic liquid with power conversion efficiency of 0.075%. The results shown the synergistic effects of the polycationic tripropyl chitosan iodide with the ionic liquid 1-propyl-3-methylimidazolium iodide on the photovoltaic performance.

ABSTRACTPoly(3,4-ethylenedioxythiophene) (PEDOT) electrodes are prepared by a novel ultrashort galvanic pulse electropolymerization technique for application in solid-state supercapacitors. Microstructure studies using scanning electron microscopy (SEM) show that PEDOT electrodes deposited by pulse polymerization are highly porous as compared to the conventional potentiostatic polymerization. In addition, as revealed by the X-ray photoelectron spectroscopy (XPS) studies in the PEDOT films formed by pulse polymerization, the polymer chains are fully conjugated with the dopant ClO4- ions. Solid-state supercapacitor cells using pulse polymerized PEDOT electrodes and ionic liquid gel polymer electrolyte were fabricated and characterized. The impedance spectroscopy studies show that the pulse polymerized PEDOT electrode have specific capacitance value of ∼ 65 F g-1 as compared to ∼52 F g-1for potentiostatically polymerized PEDOT and significantly lower interfacial and charge transfer resistance. Cyclic voltammetry (CV) and galvanostatic charge-discharge characterization show highly capacitive behavior of the supercapacitor cells in the solid-state configuration.
