“…Based on Debye-Scherrer equation, the broader the diffraction peak width, the shorter the crystallite size. Samples with lower crystallinity exhibits higher ionic conductivity [26]. Thus the decrease in intensity and broadening of the peaks indicates the increase in amorphous region as a result of disruption of the crystalline domain of the chitosan by the NaTf salt.…”

Solid polymer electrolytes based on chitosan NaCF 3 SO 3 have been prepared by the solution cast technique. X-ray diffraction shows that the crystalline phase of the pure chitosan membrane has been partially disrupted. The fourier transform infrared (FTIR) results reveal the complexation between the chitosan polymer and the sodium triflate (NaTf) salt. The dielectric constant and DC conductivity follow the same trend with NaTf salt concentration. The increase in dielectric constant at different temperatures indicates an increase in DC conductivity. The ion conduction mechanism follows the Arrhenius behavior. The dependence of DC conductivity on both temperature and dielectric constant ( dc ( , ) = 0 − / ) is also demonstrated.

“…Room temperature ionic liquids (RTILs) are molten organic salt consisting of bulky organic cations with delocalized charges and organic or inorganic anions [1]. RTILs are promising candidates because of their inherent physical and chemical characteristics such as nonvolatility, nonflammability, negligible vapor pressure, low melting point, low toxicity, high conductivity and excellent thermal and electrochemical stabilities as well as a wide electrochemical window [1][2][3].…”

Thin films of biodegradable corn starch-based biopolymer electrolytes were prepared by solution casting technique. Lithium hexafluorophosphate (LiPF 6 ) and 1-butyl-3-methylimidazolium trifluoromethanesulfonate (BmImTf) were employed as lithium salt and ionic liquid, respectively. With reference to the temperature dependence study, Arrhenius relationship was observed. The highest ionic conductivity of (6.00 ± 0.01) × 10 −4 S cm −1 was obtained at 80°C. Based on x-ray diffraction (XRD) result, the peaks became broader with doping of ionic liquid revealing the higher amorphous region of the biopolymer electrolytes. Ionic liquid-based biopolymer electrolytes exhibited lower glass transition temperature (T g ).

“…As temperature increases, more local empty spaces and free volumes for the segmental motion are produced. This facilitates the migration of ions [16]. Rise in temperature also increase the dissociation of MPII and thus yields greater number of free ions.…”

Effect of Temperature on the Transport Property of PVdF-HFP-MPII-PC/DME Gel Polymer ElectrolytesAbstract. Gel polymer electrolytes employing the co-polymer poly(vinylidene fluoride-co-hexafluoropropylene) (PVdF-HFP) as the polymer host were prepared by soaking the PVdF-HFP films in a liquid electrolyte of 1.0M 1-methyl-3-propyl imidazolium iodide (MPII) ionic liquid dissolved in a mixture of propylene carbonate (PC) and 1,2-dimetoxyethane (DME) (v/v=7:3). Conductivity of PVdF-HFP-MPII-PC/DME electrolyte was investigated as a function of temperature. Conductivity enhancement with temperature is attributed to the increase in the number, n and mobility, μ of free ions. The n and μ of free ions have been determined quantitatively by impedance spectroscopy.
