In this work, solid polymer electrolyte compose of blended 30% poly (methyl methacrylate) grafted natural rubber (MG30)-poly (ethyl methacrylate) (PEMA) polymer blend doped with Lithium trimethasulfonate (LiCF3SO3) films were prepared by solution casting technique. . FTIR analysis showed that the interactions between lithium ions and oxygen atoms occur at the carbonyl functional group C=O where there is shifting in wavenumber from 1728 cm-1 of pure blend to lower wavenumber of blended MG30-PEMA on the MMA structure in both MG30 and PEMA. DSC analysis showed miscibility of polymer blend. From Electrochemical Impedance Spectrocopy analysis, ionic conductivity increase with the increasing of salt concentration. Maximum conductivity at room temperature is 9.20 x 10-6 Scm-1 was obtained when 30 wt% of LiCF3SO3 was added into the system. Ionic conductivity temperature dependence plots found obeys the Arrhenius rule.

The sole aim of the present article is to develop an ionic liquid (IL)-doped solid polymer electrolyte for an electrochemical double-layer capacitor (EDLC). A solution cast technique was adopted to develop a solid polymer electrolyte of poly (vinylidene fluoride-co-hexafluoropropylene) as host polymer and low-viscosity IL (1-ethyl-3-methylimidazolium thiocyanate) as dopant. Electrochemical impedance spectroscopy measurement showed a six orders of magnitude enhancement in conductivity ( σ) by IL doping. A linear sweep voltammetric investigation of the electrolyte films exhibited a good electrochemical stability window of 3.6 V. Polarized optical microscopy of the synthesized films revealed a reduction in crystallinity by IL doping. Infrared spectroscopy further affirms the composite nature of the film. The maximum conductivity value of 2.65 mS/cm is obtained for 80% of the ionic-doped system. Using maximum conductivity film and porous carbon-based electrodes, we have developed EDLCs that show a specific capacitance value of 2.36 F/g.

Palm-based polyurethane electrolyte was prepared via prepolymerization method between palm kernel oil polyol (PKO-p) and 2,4′-diphenylmethane diisocyanate (MDI) in acetone at room temperature with the presence of lithium trifluoromethanesulfonate (LiCF3SO3). The effect of varying the concentration of LiCF3SO3salt on the ionic conductivity, chemical interaction, and structural and morphological properties of the polyurethane solid polymer electrolyte was investigated. The produced film was analyzed using electrochemical impedance spectroscopy (EIS), attenuated total reflection Fourier transform infrared (ATR-FTIR), X-ray diffraction (XRD), and scanning electron microscopy (SEM). The EIS result showed that the highest ionic conductivity was at 30 wt% LiCF3SO3with a value of 1.6 × 10−5 S·cm−1. Infrared analysis showed the interaction between lithium ions and amine group (–N–H) at (3600–3100 cm−1), carbonyl group (–C=O) at (1750–1650 cm−1), and ether group (–C–O–C–) at (1150–1000 cm−1) of the polyurethane forming polymer-salt complexes. The XRD result proved that LiCF3SO3salt completely dissociates within the polyurethane film as no crystalline peaks of LiCF3SO3were observed. The morphological study revealed that the films prepared have a good homogeneity and compatibility as no phase separation occurred.

Polymer electrolytes film based on polyethylene oxide (PEO) complexes with NaClO4 salt with a ratio of EO: Na = 20:1 and fly ash as filler has been prepared by solution casting technique. The crystallinity of the solid polymer electrolyte was characterized by X-Ray Diffraction (XRD). The interaction between PEO and Na-ions confirmed by Fourier Transform Infra Red (FTIR) analysis. The ionic conductivity of the solid polymer electrolyte was investigated by impedance analysis from 1 MHz to 1 Hz at a varied temperature of 50°C, 60°C, 70°C, 80°C, and 90°C. The maximum ionic conductivity of EO: Na = 20 was 5.31 x 10-5 S cm-1 and increases to 2.13 x 10-4 S cm-1 by the addition of fly ash 5% at the temperature of 60°C.
