“…Seo et al 41 considered that the cis-trans isomerism of TFSIis the main cause for the two secondary peaks. However, in their study, they did not clarify a question how the cis-trans isomerism of TFSI (11) affects the presence of the two secondary peaks in the g(r) plots of the Li + -TFSI -. By analyzing our MD simulations, we found that more cis-TFSI appear at the peak position of 0.32nm, while more trans-TFSI at 0.42nm (Figure 4a).…”

“…They found that this polymeric electrolyte film exhibits high polymer (3) segmental mobility, a large number of charge carriers as well as high mobility. 11 To develop novel high-safety lithium-ion battery, Yang et al improved the electrolyte by mixing pyrrolidinium-based ionic liquid with organic additive and LiTFSI. Their work indicated when the content of ionic liquid in the mixed electrolyte is 65 vol%, the LiFePO4/Li cells produced by the mixed electrolyte showed a good cycle performance at room temperature, delivering high reversible capacities in the range of 152-157 mAhg -1 at 0.1 C. 12 Borodin et al conducted computational studies on the transportations of the ions Li + in the ILs-based electrolytes.…”

In this study, novel ionic liquid-incorporated Zn-ion conducting polymer electrolyte membranes containing polymer matrix poly (vinylidene fluoride-hexafluoropropylene) (PVdF-HFP) and 1-ethyl-3-methylimidazolium trifluoromethanesulfonate (EMITf), along with zinc trifluoromethanesulfonate Zn(Tf)2, are prepared and investigated. It is ascertained that the optimal membrane ILPE-Zn-4 (the mass ratio of EMITf:Zn(Tf)2:PVDF-HFP is 0.4:0.4:1), with abundant nanopores, exhibits a high amorphousness. At room temperature, the optimized electrolyte membrane offers a good value of ionic conductivity (~1.44 × 10−4 S cm−1), with a wide electrochemical stability window (~4.14 V). Moreover, the electrolyte membrane can sustain a high thermal decomposition temperature (~305 °C), and thus its mechanical performance is sufficient for practical applications. Accordingly, the ionic liquid-incorporated Zn-ion conducting polymer electrolyte could be a potential candidate for Zn-based energy storage applications.

The polymer electrolyte system of chitosan/dextran-NaTf with various glycerol concentrations is prepared in this study. The electrical impedance spectroscopy (EIS) study shows that the addition of glycerol increases the ionic conductivity of the electrolyte at room temperature. The highest conducting plasticized electrolyte shows the maximum DC ionic conductivity of 6.10 × 10−5 S/cm. Field emission scanning electron microscopy (FESEM) is used to investigate the effect of plasticizer on film morphology. The interaction between the electrolyte components is confirmed from the existence of the O–H, C–H, carboxamide, and amine groups. The XRD study is used to determine the degree of crystallinity. The transport parameters of number density (n), ionic mobility (µ), and diffusion coefficient (D) of ions are determined using the percentage of free ions, due to the asymmetric vibration (υas(SO3)) and symmetric vibration (υs(SO3)) bands. The dielectric property and relaxation time are proved the non-Debye behavior of the electrolyte system. This behavior model is further verified by the existence of the incomplete semicircle arc from the Argand plot. Transference numbers of ion (tion) and electron (te) for the highest conducting plasticized electrolyte are identified to be 0.988 and 0.012, respectively, confirming that the ions are the dominant charge carriers. The tion value are used to further examine the contribution of ions in the values of the diffusion coefficient and mobility of ions. Linear sweep voltammetry (LSV) shows the potential window for the electrolyte is 2.55 V, indicating it to be a promising electrolyte for application in electrochemical energy storage devices.
