“…3 it can be observed that the NCPE-15 film has the smooth surface morphology. The morphology of the smooth surface of the NCPE-15 film is closely related to the decrease in the crystallinity of NCPE films [42] this helps the ionic transport in the polymer electrolyte, thereby increasing the ionic conductivity [43].…”

Nanocomposite Polymer Electrolyte (NCPE) films based on a blend of two polymers poly (ethylene oxide) (PEO) and poly (vinylidene fluoride) (PVDF) complexed with sodium perchlorate (NaClO4) salt and Nano-filler Titanium dioxide (TiO2) (i.e., (80wt%PEO/20wt%PVDF) + 7.5wt%NaClO4+ xwt%TiO2 where x = 3, 6, 9, 12, 15, and 18) were prepared and characterized as potential candidates for battery applications.Electrochemical Impedance Spectroscopy (EIS) has been employed between the frequencies 10 Hz and 4 MHz to investigate electrical, dielectric and electric modulus properties of the prepared NCPE films. Effect of TiO2 Nano-filler concentration on the structural, ionic conductivity, and dielectric relaxation has been studied. The AC conductivity of the NCPE films at high frequencies obeys Jonscher's power law. The values of DC ionic conductivity calculated by fitting the AC conductivity spectra to the best fit of Joncher's power law are consistent with the values of DC ionic conductivity calculated from the bulk resistance (Rb) of the NCPE films. The ionic conductivity that depends on temperature follows the Arrhenius rule between the temperatures 298 K and 328 K. The maximum ionic conductivity at ambient temperature 8.75x10 -5 S/cm was obtained for (80wt%PEO/20wt%PVDF) +7.5wt%NaClO4 +15wt%TiO2 NCPE film and it is attributed to the decrease in crystallinity. Using Wagner's polarization technique ionic transport numbers of various NCPE films were measured.

“…It is clear that thenano-composite solid polymer electrolytes with low activation energy can provide a relatively easy ion migration through polymer electrolyte. Singh et al prepared a PEO/AgI polymer electrolyte incorporated with Al 2 O 3 and SiO 2 nano-fillers and recorded a conductivity of 5.78 × 10 −6 and 7.032 × 10 −6 S cm −1 , respectively [69].…”

This report presents the preparation and characterizations of solid biopolymer blend electrolyte films of chitosan as cationic polysaccharide and anionic dextran (CS: Dextran) doped with ammonium iodide (NH4I) to be utilized as electrolyte and electrode separator in electrical double-layer capacitor (EDLC) devices. FTIR and XRD techniques were used to study the structural behavior of the films. From the FTIR band analysis, shifting and broadening of the bands were observed with increasing salt concentration. The XRD analysis indicates amorphousness of the blended electrolyte samples whereby the peaks underwent broadening. The analysis of the impedance spectra emphasized that incorporation of 40 wt.% of NH4I salt into polymer electrolyte exhibited a relatively high conductivity (5.16 × 10−3 S/cm). The transference number measurement (TNM) confirmed that ion (tion = 0.928) is the main charge carriers in the conduction process. The linear sweep voltammetry (LSV) revealed the extent of durability of the relatively high conducting film which was 1.8 V. The mechanism of charge storage within the fabricated EDLC has been explained to be fully capacitive behavior with no redox peaks appearance in the cyclic voltammogram (CV). From this findings, four important parameters of the EDLC; specific capacitance, equivalent series resistance, energy density and power density were calculated as 67.5 F/g, 160 ohm, 7.59 Wh/kg and 520.8 W/kg, respectively.

“…The CCPE and NCCPE films were highly dried and flexible the first 8−10% within 100 °C owing to the dehydration of the strong H 2 O bonding presence in the external or internal surface of the polymer matrix. 31 Initially, CCPE showed 13% weight loss until 90 °C followed from 90 to 290 °C with almost stable 87% mass retention capacity maintained constant. The NCCPE undergoes unstable and gradual weight loss by carrying only a 23% weight retention capacity at 416 °C.…”

The next-generation electric vehicle requires superior safety and high-energy-density batteries for better performance. Currently, solid polymer electrolytes provide better safety, high mechanical stability, and a desirable electrode-toelectrolyte interface in lithium-ion batteries compared to those in conventional battery systems. However, the ionic conductivity of solid-state electrolytes remains challenging at room and low operating temperatures. Herein, we report that incorporating a greener calcium hydroxide (CH) based nanofiller derived from natural waste seashells with polymer electrolyte gives a tremendously increased lithium-ion conductivity of 4.12 × 10 −5 S cm −1 at 25 °C. The cross-linked composite polymer electrolyte (CCPE) was prepared with PEO, LiClO 4 salt, greener nanofiller, and cross-linking monomers via the facile ultraviolet (UV) polymerization technique. The photosensitive vinyl groups of diacrylate and the thio groups of the tetrathiol monomer undergo a thiol−ene click reaction to form a highly cross-linked network with homogeneously distributed LiClO 4 and CH nanofiller. The incorporation of 15 wt % of CH greener nanofiller significantly improved the amorphous phase of the composite electrolyte and showed a wide electrochemical window of 5 V. The fine porous structure of CH greener nanofiller incorporated in the solid-state cross-linked network electrolyte channelizes for smooth lithium-ion mobility. The fabricated full cell exhibits good discharge capacity, of 160 mAh g −1 to 150 mAh g −1 at 0.1 C over 50 cycles with a high Coulombic efficiency of 95 % at 60 °C. Naturally derived, cost-effective greener nanofiller from waste seashells acts as a prominent additive to prepare solid-state electrolytes with high stability in lithium metal batteries.

“…PEO containing alkali metal ions still exhibit relatively low ionic conductivity compared to liquid/aqueous electrolytes. In general, the PEO-based composite electrolyte is a mixture of crystalline and amorphous phases with the ratio of which depends to a great extent on compositions of the electrolyte, temperature, and thermal stability (Singh et al, 2015).…”

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.
