“…High dielectric constant along with a large number of molecules with a lone pair electron belonging to GG help the salts to break up and become free Li + and Tf − ions. 18 The mobility and diffusivity of charge carriers are seen to increase up to electrolyte consisting of 40 wt% LiTf (see Figure 4(b) and (c)). Beyond this, LiTf salt content, μ and D decreased.…”

Mobility and number density of charge carriers are important parameters that influence the electrolyte conductivity. Therefore, knowing these parameters quantitatively is of great significance. In this work, solid polymer electrolytes have been prepared by solution casting technique using gellan gum complexes with lithium triflate (LiTf). The conductivity of the electrolyte increases from 3.35 × 10−8 S cm−1 (electrolyte with 10 wt% LiTf) to 5.38 × 10−4 S cm−1 (electrolyte with 40 wt% LiTf). The increase in conductivity was attributed to the increase in mobility and number density of charge carriers in the electrolyte from 6.63 × 10−9 cm2 V−1 s−1 to 1.25 × 10−6 cm2 V−1 s−1 and from 4.00 × 1020 cm−3 to 2.68 × 1021 cm−3, respectively. The electrolyte conductivity is seen to decrease as LiTf salts were added more than 40 wt% concentration due to the decrease of charge carrier mobility to 8.58 × 10−7 cm2 V−1 s−1. The variation of conductivity obtained in this work is dominantly influenced by the mobility of charge carriers in the electrolyte as proven from the Fourier transform infrared approach.

“…[20] It clearly can be seen that the R b value for ALEC-3 exhibits the minimum value of 4.95 Ω and this indicates that the sample becomes more capacitive than resistive. [19] Therefore, the fully inclined spike of sample ALEC-3 were expected to have higher ionic conductivity value in BBPEs system.…”

In this present work, the study of ionic conductivity based on bio‐based polymer electrolytes (BBPEs) containing with alginate doped glycolic acid (GA) and plasticized with ethylene carbonate (EC) is presented. The ionic conductivity of present work is determined through impedance spectroscopy over a frequency range from 50 Hz to 1 MHz. The addition of EC has improved the Cole‐Cole plot for entire samples where it revealed the combination of CPE and bulk resistant in series for their electrical equivalent circuit. It is shown that the ionic conductivity increased from 10−5 to 10−4 S cm−1 upon addition of plasticizer into BBPEs system with the optimum conductivity is obtained at 9.06 × 10−4 S cm−1 for sample containing 6 wt.% of EC. The findings show that the present system has great potential to be used in application of polymer electrolytes system.

“…To achieve excellent electrochemical performance, the polymer skeleton should provide a favorable σ and affinity for the electrolyte and favorable thermal and chemical stabilities as a separator. Various polymer matrixes, which determine the polymer electrolyte properties, have also been investigated; these include poly(vinylidene fluoride), poly(vinylidene fluoride‐ co ‐hexafluoropropylene), poly(vinyl alcohol), poly(ethylene oxide), polyacrylonitrile, Nafion, and poly(arylene ether) . Among these polymer matrixes, poly(arylene ether sulfone) (PAES) copolymers, a class of high‐performance amorphous thermoplastics with outstanding mechanical properties and thermal stabilities, have been widely used as substrate materials for proton or anion‐exchange membranes used in fuel cells and supercapacitors .…”

The low energy density of supercapacitors, especially supercapacitors based on aqueous electrolytes, is the main factor limiting their application, and the energy density is closely related to the operating potential window of the supercapacitor. The polymer electrolyte is the main contributor to the safe operation and good ion conductivity of the supercapacitor. In this study, a crosslinked quaternized poly(arylene ether sulfone) (PAES) membrane was prepared via crosslinking during membrane formation with a thermal‐only treatment and applied in an electric double‐layer capacitor (EDLC). The pre‐prepared PAES membrane formed a polymer electrolyte with 1 mol/L Li2SO4 and was then fabricated into an EDLC single cell. The properties of both the membrane and ELDC were investigated. The preferred cPAES‐N‐0.2 polymer electrolyte showed an ionic conductivity of 1.18 mS/cm. The optimized EDLC exhibited a single‐electrode gravimetric capacitance of 104.92 F/g at a current density of 1.0 A/g and a high operating potential window (1.5 V); it, thereby, achieved a high energy density of 8.20 W h/kg. The EDLC also exhibited excellent cycling properties over 3000 charge–discharge cycles. The crosslinked structures promoted the tensile strength and thermal stability of the PAES membranes; this was accompanied by a slight decrease in the ionic conductivity. © 2019 Wiley Periodicals, Inc.
