“…The charge carrier density is high at higher salt concentrations, limiting the amount of space available for free ions to move. This phenomenon caused the collision rate to increase, and hence, and D decrease (Noor 2020;Chai et al 2020). It is observed that dc and ′ follows the same trend from S0 to S30 samples, implying that dc ∝ n ∝ � .…”

In this paper, we report the effect of doping sodium iodide (NaI) salt into a polymer blend matrix of sodium carboxymethyl cellulose (NaCMC) and poly(vinyl alcohol) (PVA). Solution casting approach was used to prepare solid polymer electrolyte (SPE) films. The films were characterized by Fourier-transform infrared spectroscopy (FTIR), X-Ray diffraction (XRD), electrical impedance spectroscopy, thermogravimetric analysis (TGA), and differential scanning calorimetry (DSC). XRD showed that NaI incorporation decreased the crystallinity of NaCMC/PVA-based SPE. FTIR technique confirmed the complexation of salt with polymer matrix due to the formation of the coordination bond between Na+ and –OH group and hydrogen bond between I− and –CH group. The sample with 30 wt% NaI showed the highest conductivity of 2.52 × 10–3 S cm−1, strongly influenced by the highest charge concentration $$(n)$$ ( n ) , not its mobility (μ). DSC analysis revealed an increase in glass transition temperature $$({T}_{g})$$ ( T g ) with increasing salt content. TGA studies showed a decrease in thermal stability with salt inclusion. The transference number was found to be 0.99 for the highest conducting sample showing the primary charge carriers are ions. The highest conducting sample exhibited a mechanical strength of 15.42 MPa at room temperature, and it has been used to fabricate a battery to evaluate its suitability in energy storage devices.

“…The decreased in both μ and D are associated with the increase in collision between TPA + , I and I 3 ions during conduction. 18,30 This is because the amounts of free ions present in the electrolyte are now increased due to the increase in temperature as observed in Figure 5, forcing the free ions to tend to collide with each other as they flow, hence reducing their kinetic energy. The collision of surface-bound ions in the Stern-layer also induces the ion mobility to be lower.…”

Determining the transport properties of charge carriers is essential to understand the factors that affect the conductivity trend of a polymer electrolyte system. In this work, charge carrier transport parameters of polyethylene oxide–based gel polymer electrolytes were estimated from fitting the Nyquist plot with the impedance equation, derived from the equivalent circuit that consists of a resistor in series with a constant phase element. The increase in electrolyte conductivity with temperatures from 303 K to 373 K is attributed to the increase of free ions, n (TPA+ cations and I¯ anions) and not to ionic mobility, μ. The decrease in μ with temperature is associated with the increase in the Stokes drag coefficient due to increase in ion collisions. This work explains how conductivity changes with number density of ions and mobility at various temperatures.

“…Jatropha oil-based PUA was synthesised by a three-step process: epoxidation, hydroxylation and the introduction of the acrylate group in the urethanation process 27 , 34 . During the epoxidation process, the jatropha oil was pre-mixed with formic acid under mechanical stirring using an overhead stirrer at 313 K. Hydrogen peroxide was added slowly into the mixture using a dropping funnel to prevent over heating of the mixture solution.…”

Jatropha oil-based polyurethane acylate gel polymer electrolyte was mixed with different concentrations of tetrabutylammonium iodide salt (TBAI). The temperature dependences of ionic conductivity, dielectric modulus and relaxation time were studied in the range of 298 to 393 K. The highest ionic conductivity of (1.88 ± 0.020) × 10–4 Scm−1 at 298 K was achieved when the gel contained 30 wt% of TBAI and 2.06 wt% of I2. Furthermore, the study found that conductivity-temperature dependence followed the Vogel-Tammann Fulcher equation. From that, it could be clearly observed that 30 wt% TBAI indicated the lowest activation energy of 6.947 kJ mol−1. By using the fitting method on the Nyquist plot, the number density, mobility and diffusion coefficient of the charge carrier were determined. The charge properties were analysed using the dielectric permittivity, modulus and dissipation factor. Apart from this, the stoke drag and capacitance were determined.
