“…Besides, the O–H bands are also credited to the NH 4 + asymmetry which explains the bending of NH 4 + that could result in a greater tendency for the H + to be released [ 64 ]. Moreover, the bands located at 2957 cm −1 and 2895 cm −1 in CSMCD1 are due to the C–H stretching, symmetrically and asymmetrically [ 21 , 65 ]. It is noticed that the C-H symmetrical stretching is shifted to a lower wavenumber (WN) of 2954 and 2950 cm −1 in CSMCD2 and CSMCD3, respectively.…”

“…CS is produced from the deacetylation process of chitin and because of its chemical composition, the inclusion of (OH and NH 2 ) in its backbone structure, CS can be a strong ionic conductor [ 18 , 19 , 20 ]. Moreover, due to several properties such as good thermal and mechanical strength as well as biocompatibility, methylcellulose (MC) is also usually used as a polymer host component in polymer electrolyte synthesis [ 21 ]. MC is a derivative of cellulose that has the amphiphilic ability due to the various hydrophilic carboxyl and hydrophobic polysaccharides present in the chemical backbone.…”

In this work, a pair of biopolymer materials has been used to prepare high ion-conducting electrolytes for energy storage application (ESA). The chitosan:methylcellulose (CS:MC) blend was selected as a host for the ammonium thiocyanate NH4SCN dopant salt. Three different concentrations of glycerol was successfully incorporated as a plasticizer into the CS–MC–NH4SCN electrolyte system. The structural, electrical, and ion transport properties were investigated. The highest conductivity of 2.29 × 10−4 S cm−1 is recorded for the electrolyte incorporated 42 wt.% of plasticizer. The complexation and interaction of polymer electrolyte components are studied using the FTIR spectra. The deconvolution (DVN) of FTIR peaks as a sensitive method was used to calculate ion transport parameters. The percentage of free ions is found to influence the transport parameters of number density (n), ionic mobility (µ), and diffusion coefficient (D). All electrolytes in this work obey the non-Debye behavior. The highest conductivity electrolyte exhibits the dominancy of ions, where the ionic transference number, tion value of (0.976) is near to infinity with a voltage of breakdown of 2.11 V. The fabricated electrochemical double-layer capacitor (EDLC) achieves the highest specific capacitance, Cs of 98.08 F/g at 10 mV/s by using the cyclic voltammetry (CV) technique.

“…It has also been used by mixing with potato starch [29], maize starch [30] and chitosan [31]. This is due to unique properties of MC, such as non-toxicity, biocompatibility, mechanical strengthens and thermal stability [32]. The ionic conductivity of an electrolyte has to be determined and sufficient to be used in energy devices.…”

This report shows a simple solution cast methodology to prepare plasticized polyvinyl alcohol (PVA)/methylcellulose (MC)-ammonium iodide (NH4I) electrolyte at room temperature. The maximum conducting membrane has a conductivity of 3.21 × 10−3 S/cm. It is shown that the number density, mobility and diffusion coefficient of ions are enhanced by increasing the glycerol. A number of electric and electrochemical properties of the electrolyte—impedance, dielectric properties, transference numbers, potential window, energy density, specific capacitance (Cs) and power density—were determined. From the determined electric and electrochemical properties, it is shown that PVA: MC-NH4I proton conducting polymer electrolyte (PE) is adequate for utilization in energy storage device (ESD). The decrease of charge transfer resistance with increasing plasticizer was observed from Bode plot. The analysis of dielectric properties has indicated that the plasticizer is a novel approach to increase the number of charge carriers. The electron and ion transference numbers were found. From the linear sweep voltammetry (LSV) response, the breakdown voltage of the electrolyte is determined. From Galvanostatic charge-discharge (GCD) measurement, the calculated Cs values are found to drop with increasing the number of cycles. The increment of internal resistance is shown by equivalent series resistance (ESR) plot. The energy and power density were studied over 250 cycles that results to the value of 5.38–3.59 Wh/kg and 757.58–347.22 W/kg, respectively.

“…In addition, the observed peak ascribed to the NH 4 + asymmetry elucidates a high tendency of the NH 4 + distortion to release H + ions [ 52 ]. Furthermore, the -CH symmetrical stretching and -CH asymmetrical stretching are found at the band region of (ii) 3050 to 2850c m −1 [ 53 , 54 ]. It is noticed that the intensity of the -CH bands is increased as the concentration of glycerol increases which signified the complex development between the glycerol and CS-MC-NH 4 NO 3 [ 55 ].…”

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.
