AbstractJatropha 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.

A sago-based gel polymer electrolyte (GPE) was prepared by mixing native sago with potassium hydroxide (KOH) aqueous in order to investigate the applicability of GPE to zinc-air (Zn-air) battery. The viscosity and conductivity of the sago GPE were evaluated using varying sago amounts and KOH concentrations. The viscosity of the sago GPE was kept as a reserve in the region of ~ 0.2 Pa s as the KOH concentration was increased from 2 to 8 M. Sago GPE was found to have an excellent ionic conductivity of (4.45  0.1) x 10-1 S cm-1 with 6 M KOH. GPE was also employed in an experimental Znair battery using porous Zn electrode as the anode. The battery shows outstanding discharge capacity and practical capacity obtained of 505 mA h g-1.

Secondary batteries based on ion conduction are among the most promising technology for next generation mobile and stationary storage system due to their unmatched volumetric energy density. However the multiple emerging challenges which include electrochemical stability, transport efficiency and safety issues of these secondary batteries have attracted worldwide attention. The perspective of this review is that rational design of polymeric separator which is an essential component in rechargeable batteries separating anode and cathode, and controlling number of mobile ions is crucial to overall battery performance, including lifetime, safety as well as energy and power density of battery. There is impressive progress in the exploration of separator materials. Among them, poly(vinylidene fluoride-co-hexafluoropropylene) P(VdF-co-HFP) have received great attention as polymer host due to some its splendid collective property such as its amorphous nature, high room temperature ionic conductivity, high dielectric constant and the possibility of controlling the porosity of the materials through binary and ternary polymer/solvent systems. This review focuses specifically on recent advances in P(VdF-co-HFP) based separator cum gel polymer electrolyte with detailed analysis of several embedded functional agent that are incorporated to improve ionic conductivity, mechanical robustness and thermal stability of rechargeable batteries.

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.

Methyl-grafted natural rubber (MG30) was treated with N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine (6PPD) to enhance it anti-aging properties. The treated MG30 was used as polymer electrolyte by incorporating lithium trifluoromethane sulfonate (LiTF) through solution-cast technique. The impedance behavior of the sample has been carried out by analyzing the dielectric permittivity, dissipation factor, dielectric modulus and ionic conductivity as a function of temperature at different frequencies through impedance spectroscopy. Keywords: Methyl-grafted natural rubber, polymer electrolyte, N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine, ionic conductivity, dielectric.
