“…Complete polarization can be observed as the current value begins to stabilize at 0.7 μA. The high value at the initial seconds, rapid current drop and current stabilization are the indicator of an ionic conductor [ 19 ]. The t ion and t el for CS -glycerol-Mg(CH 3 COO) 2 -Ni are 0.96 and 0.04, respectively.…”

The current work shows the preparation of plasticized chitosan-magnesium acetate Mg(CH3COO)2-based polymer electrolyte dispersed with nickel (Ni) metal complexes via solution casting. Investigations of electrical and electrochemical properties of the prepared polymer composite electrolyte were carried out. The structural and optical properties of the samples were studied using X-ray diffraction (XRD) and UV-Vis spectroscopy techniques. The structural and optical outcomes revealed a clear enhancement in both absorbance and amorphous nature of the samples upon the addition of Ni metal complexes. Through the simulation of impedance data, various ion transport parameters were calculated. The electrochemical performance of the sample was examined by means of transference number measurement (TNM), linear sweep voltammetry (LSV) and cyclic voltammetry (CV) measurements. The TNM analysis confirmed the dominance of ions as the main charge carrier in the electrolyte with tion of (0.96) compared to only (0.04) for tel. The present electrolyte was stable in the range of 0 V to 2.4 V, which was obtained from linear sweep voltammetry (LSV). A result from CV proved that the electrical double-layer capacitor (EDLC) has a capacitive behavior as no redox peaks could be observed. The presence of Ni improved the charge–discharge cycle of the EDLC due to its amorphous behavior. The average performances of the EDLC were recorded as 41.7 F/g, 95%, 5.86 Wh/kg and 628 W/kg for specific capacitance, coulombic efficiency, energy and power densities, respectively. The fabricated EDLC device was found to be stable up to 1000 cycles.

“…This is due to the weakening of the attractive force between polymer chains. It has been reported in [ 19 ] that the transport properties such as ionic mobility, diffusivity and number density of starch-based electrolyte depend on the amount of magnesium sulphate (MgSO 4 ).…”

Solid polymer electrolytes based on starch and magnesium sulphate were prepared via a casting method. The solid polymer electrolyte (SPE) films were an amorphous phase and the XRD analyses confirmed the coexistence of peaks for the materials mentioned. The films seemed to be coarse, as clarified by SEM, and the surface was evenly shaped. Sample of 35 wt.% MgSO 4 showed the utmost ionic conductivity (8.52×10 -5 Scm -1 ). The open circuit voltage (OCV) results for the fabricated cells can maintain a voltage of above 1.4 V for 14 days, by using the as-prepared films. The electrochemical preliminary results revealed that the as-prepared SPE has the ability to be employed in all-solid-state zinccarbon battery.

“…In recent years, the usage of solid polymer electrolytes (SPE) has grown in demand compared to liquid electrolytes due to the evolutional in electrochemical devices specifically in rechargeable batteries, solar cells, supercapacitors, sensors and semiconductors [1][2][3][4][5]. Commonly, most of the previous works used an inorganic polymer and inorganic solvent as starting materials in SPE film preparation.…”

In this paper, the mechanical properties of corn starch-sodium bisulfite (NaHSO3) solid polymer electrolyte (SPE) were investigated. The SPE film based on corn starch was doped with different weight percentages (wt%) of NaHSO3 and prepared using a solution casting method. The SPE was tested by using the Tensile Analyzer to determine the tensile strength and Young’s modulus value. The presence of 5 wt% of NaHSO3 content within the corn starch matrix increased the mechanical properties of SPE film from 0.26 MPa to 2.11 MPa of tensile strength while Young’s modulus enlarged from 1.6  10-2 up to 2.6  10-2 MPa. There was found that the tensile strength and Young’s modulus values tended to decrease with the addition of NaHSO3 more than 5 wt%. This study highlighted that adding NaHSO3 not only improved the ionic conductivity but also changed the mechanical properties of the film itself and it is believed that these properties had the potential and beneficial not only in advanced electronic applications but also in the packaging industry.
