The concern about environmental problems has inspired a of energy storage devices from natural sources. In this study, solid polymer electrolyte (SPE) films made from corn starch doped with different compositions of sodium iodate (NaIO3) were prepared via the solution casting technique. The effect of dopants on the structure, morphology and electrical properties of SPE films was analysed using X-Ray diffraction (XRD), scanning electron microscopy (SEM) and electrochemical impedance spectroscopy (EIS) analysis. From the XRD, it shows that the amorphous state would influence the conductivity values of SPE films. Then, the SEM observations revealed that the films seem to be rough, porous and having branch structure, which may affect the conductivity of SPE films. The maximum conductivity of SPE film is obtained from 3 wt.% of NaIO3 with a value of 1.08 × 10−4 Scm−1 at room temperature (303K). From the results, this SPE is proposed to have a great potential in future energy storage applications.

“…Therefore, relaxation time decreases with increase of temperature which results in an increase in the ionic conductivity. The dielectric loss at lower frequencies characterized by high values of tan δ is due to the contribution of both ion jump and conduction or ion migration loss in addition to the polarization loss [49,50]. The loss tangent shows a maximum at low frequency end in the high temperature region because of thermally generated defects in the sample [51].…”

Solid nanocomposite polymer electrolytes based on polyethylene oxide (PEO), AgNO 3 as salt, and nanosized Fe 2 O 3 (less than 50 nm size) as filler are prepared by hot press method. In (100-x) PEO:xAgNO 3 system (where x=5≤x≤ 50 wt%), the solid polymer electrolyte 90PEO:10AgNO 3 gives highest ionic conductivity. This composition is further used as host matrix and Fe 2 O 3 as filler for the preparation of solid nanocomposite polymer electrolytes (100-x) (90PEO:10AgNO 3 ):xFe 2 O 3 (where x=5≤x≤30 wt%). The real impedance (Z') and imaginary impedance (Z") of the samples are analysed using LCR meter. The maximum ionic conductivity is observed for 10 wt% of filler Fe 2 O 3. The optimum conducting composition 90(90PEO:10AgNO 3 ):10Fe 2 O 3 is used for further study. The dielectric response of the samples is analysed using dielectric constant (ε'), dielectric loss (ε"), loss tangent (tanδ), and real and imaginary part of electric modulus (M' and M"). The ionic conductivity and dielectric response of the solid nanocomposite polymer electrolytes are studied within the frequency range of 100 Hz-5 MHz and within the temperature range of 300-323 K. It is observed that the dielectric constant rises sharply towards low frequencies due to electrode polarization effects. The maxima of the loss tangent (tan δ) shift towards higher frequencies with increasing temperature. The enhancement in ionic conductivity is observed when nanosized Fe 2 O 3 filler is added into the solid polymer electrolyte.

Rapid decay of photoanode, leakage from sealant, and evaporation of electrolyte are always the major concerns of quantum dot-sensitized solar cells (QDSCs) based on liquid electrolyte. Subsequently, gel polymer electrolyte (GPE) appears as an attractive solution in addition to lower cost, lighter weight, and flexibility. Poly(acrylamide- co-acrylic acid) (PAAm-PAA) is of special interest to act as a polymer host to entrap liquid electrolyte because it provides high transparency, good gelatinizing properties, and excellent compatibility with the liquid electrolyte. In this work, the electrical and transport properties of PAAm-PAA GPE incorporating with water-soluble sodium sulfide were characterized by impedance spectroscopy. An increment of ionic conductivity was observed with the incorporation of ethylene carbonate (EC) and potassium chloride (KCl). The highest room temperature ionic conductivity of PAAm-PAA GPE is 70.82 mS·cm−1. QDSC based on PAAm-PAA GPE with the composition of 1.3 wt% of KCl, 0.9 wt% of EC, 55.3 wt% of PAAm-PAA, 38.5 wt% of sodium sulfide, and 4.0 wt% of sulfur can present up to 1.80% of light-to-electricity conversion efficiency.
