“…The conductivity is quite low and expected to be increased with addition of plasticizers or ionic liquid [36,37]. According to Minami et al [38], ionic conductivity in solid polymer electrolytes based on polyether complexed with salt is lower compared to other polymers.…”

Abstract:Castor oil-based polyurethane as a renewable resource polymer has been synthesized for application as a host in polymer electrolyte for electrochemical devices. The polyurethane was added with LiI and NaI in different wt% to form a film of polymer electrolytes. The films were characterized by using attenuated total reflectance-Fourier transform infrared spectroscopy, dynamic mechanical analysis, electrochemical impedance spectroscopy, linear sweep voltammetry and transference number measurement. The highest conductivity of 1.42 × 10 upon addition of 30 wt% NaI at room temperature. The temperature dependence conductivity plot indicated that both systems obeyed Arrhenius law. The activation energy for the PU-LiI and PU-NaI systems were 0.13 and 0.22 eV. Glass transition temperature of the synthesized polyurethane decreased from −15.8 °C to ~ −26 to −28 °C upon salts addition. These characterizations exhibited the castor oil-based polyurethane polymer electrolytes have potential to be used as alternative membrane for electrochemical devices.

“…The diameter expansion of thesemicircles shows an increase in the interface resistance after polarization, thereby restraining the diffusion of lithium ions and the subsequent transfer reaction. The Li-ion transference number ( Li + ) represents the charge of the interface resistance before and after polarization and is calculated using (4). The values of the parameters are listed in Table 4.…”

“…However, the organic electrolyte is volatile, toxic, and explosive to the environment, and the development of LIBs has been limited. Therefore, ionic liquid gel polymer electrolytes (ILGPEs) that do not leak and have good electrochemical stability as well as high conductivity have increasingly drawn the attention of researchers in recent years [1][2][3][4]. With respect to ILGPEs, ionic liquids have more advantages than other liquid electrolytes, such as a higher dielectric constant, no combustibility, higher thermal stability, and less volatility [5].…”

A new type of nanopolypyrrole/organically modified montmorillonite-ionic liquid gel polymer electrolyte (ppy/OMMT-ILGPE) is prepared based on nanopolypyrrole/organically modified montmorillonite (ppy/OMMT), N-butyl-N-methylpyrrolidinium bis(trifluoromethanesulfonyl)imide (PP14TFSI), lithium-bis(trifluoromethanesulfonyl) (LiTFSI), polyvinylidene difluoride (PVDF), methyl methacrylate (MMA), and benzoyl peroxide (BPO) by an in situ method. The effect of nano-ppy/OMMT on the physical and electrochemical properties of an ionic liquid gel polymer electrolyte is demonstrated. The results show that nanoppy/OMMT-ILGPE has a porous structure with a large surface area, and the diameter of the pores on the surface is approximately 1-2 m. The Li + transference number of 0.72 is achieved, and the ionic conductivity reaches up to 1.2 × 10 −3 S/cm at room temperature. Nano-ppy/OMMT-ILGPE has good thermal stability and mechanical properties. Meanwhile, nano-ppy/OMMT-ILGPE has fine cycle performance in the Li|nano-ppy/OMMT-ILGPE|LiNi 1/3 Co 1/3 Mn 1/3 O 2 coin cell. The good electrochemistry performance of nano-ppy/OMMT-ILGPE means that it can act as an ideal gel polymer electrolyte material for lithium ion batteries.

“…The TGA curve of PUs without ILs shows a one-step decomposition mode with the onset temperature (T ON ) at 299.68C and the end set temperature (T EN ) at 364.98C, due to the decomposition of urethane linkage and the decomposition of soft block in the PUs, respectively [27]. The TGA curve of PU-5.96 show a two-step decomposition: the first (T 1ON ) in the region of 23022608C which could be attributed to the decomposition of urethane bond, and the second (T 2ON ) in the region of 30023808C owing to the decomposition of imidazolium ring and polyols [28]. From the TGA analysis, it can be concluded that the PUs modified by ILs do not decompose if the processing temperature is below 2308C.…”

An in situ embed ionic liquid method is designed and employed in thermoplastic polyurethanes (PUs). Unlike the traditional physically incorporated antistatic polymers where conductive fillers do not firmly combined with the matrix. This permanently antistatic PUs are successfully synthesized by using a novel polyester diol bonded with ionic liquids (ILs), which are obtained by an esterification. The ILs and novel polyester polyol are successfully synthesized and subsequently characterized by Fourier transform infrared spectroscopy (FTIR) and nuclear magnetic resonance spectrum ( 1 H NMR), respectively. The effects of ILs content, temperature, and relative humidity (RH) on the surface resistivity of PUs are studied by surface resistivity tests. It is found that the surface resistivity of PUs dramatically decreases with the increment of ILs and are insensitive to surrounding environment. The surface resistivity of PUs with 5.96 wt% ILs reaches 10 10 X cm 22 order of magnitude. The crystalline properties, thermal decomposition behaviors and mechanical properties of synthesized PUs are investigated by X-ray diffraction (XRD), thermal gravimetric analysis (TGA) and tensile test respectively. The crystallinity of PUs with ILs is lower than that of pure PUs. Moreover, we also investigate the effect of ILs on the surface morphology of the PUs. POLYM.ENG. SCI., 56:629-635,
