“…The ionic contribution in poly (ethyl methacrylate)-NH 4 I system with 60:40 ratio has been documented to be 0.85 [66]. Moreover, in another study, the t ion has been recorded to be 0.905 for SPE of cellulose acetate-NH 4 I incorporated with polycarbonate and zinc sulfate as plasticizer and filler [67].…”

In this work, preparation and application of solid polymer blend electrolytes (SPBEs) based on chitosan: methylcellulose (CS:MC) incorporated with various amounts of ammonium iodide (NH 4 I) salt are described. Solution cast technique was adapted for the preparation of the SPBE films. Structural investigation and extent of interaction of the NH 4 I salt with the CS:MC film surface were conducted through X-ray diffraction (XRD) and Fourier transform infrared (FTIR) spectroscopy measurements. Electrical DC conductivity of the prepared samples was studied by electrochemical impedance spectroscopy. It is confirmed through transference number (TNM) analysis that ions are the dominant charge carrier in the polymer electrolyte system, in which the ionic (t ion ) and electron (t el ) transference numbers were found to be 0.934 and 0.036, respectively. Through the use of linear sweep voltammetry (LSV), the CS:MC:NH 4 I system is found to experience electrolyte degradation at 2.1 V. The polymer blend electrolyte sample with highest DC conductivity property was also used as separator in electrical double-layer capacitor (EDLC) cell. Two identical activated carbon electrodes were used to sandwich the electrolyte film. Cyclic voltammetry (CV) was used to show the capacitive behavior of the fabricated EDLC cell, in which no redox peaks were observed. The EDLC was examined for 100 cycles at current density of 0.2 mA/cm 2 . The values of specific capacitance and equivalent series resistance were determined to be 1.76 F/g, and 650 to 1050 Ω, respectively.

Proton conducting solid polymer electrolytes comprising PEO: PVP blend with ammonium nitrate in different compositions are prepared by solution casting technique and they are characterized with different techniques. X-ray diffraction (XRD) shows that the prepared polymer electrolytes have amorphous nature. Fourier transform infrared(FTIR) spectroscopy confirms the functional groups present in the polymer membranes. The scanning electron microscopical(SEM) images confirm the presence of smooth surface in the polymer electrolytes. The ionic conductivity values are calculated by ac impedance technique. The maximum ionic conductivity is obtained for 12 wt% ammonium nitrate doped polymer system at ambient temperature (6.39 × 10−5 S/cm). From the transference number analysis by Wagner’s polarization technique, the type of conductivity, mobility and charge-carrier concentration are confirmed. Electrochemical performance is also investigated using cyclic voltammetry (CV) studies.

The fabrication of energy storage EDLC in this work is achieved with the implementation of a conducting chitosan–methylcellulose–NH4NO3–glycerol polymer electrolyte system. The simple solution cast method has been used to prepare the electrolyte. The impedance of the samples was fitted with equivalent circuits to design the circuit diagram. The parameters associated with ion transport are well studied at various plasticizer concentrations. The FTIR investigation has been done on the films to detect the interaction that occurs among plasticizer and polymer electrolyte. To get more insights into ion transport parameters, the FTIR was deconvoluted. The transport properties achieved from both impedance and FTIR are discussed in detail. It was discovered that the transport parameter findings are in good agreement with both impedance and FTIR studies. A sample with high transport properties was characterized for ion dominancy and stability through the TNM and LSV investigations. The dominancy of ions in the electrolyte verified as the tion of the electrolyte is established to be 0.933 whereas it is potentially stable up to 1.87 V. The rechargeability of the EDLC is steady up to 500 cycles. The internal resistance, energy density, and power density of the EDLC at the 1st cycle are 53 ohms, 6.97 Wh/kg, and 1941 W/kg, respectively.
