“…However, commercial lithium ion batteries which use organic solvents as electrolytes suffer from potential safety risks such as combustion, leakage and explosion . Compared to liquid electrolytes, solid polymer electrolytes (SPEs) are safer and have attractive features such as good interfacial stability against lithium anodes and excellent mechanical properties . Various SPEs have been used as the replacement of liquid organic electrolytes for lithium ion batteries.…”

To improve the electrochemical properties and enhance the mechanical strength of solid polymer electrolytes, series of composite polymer electrolytes (CPEs) were fabricated with hybrids of thermoplastic polyurethane (TPU) electrospun membrane, polyethylene oxide (PEO), SiO2 nanoparticles and lithium bis(trifluoromethane)sulfonamide (LiTFSI). The structure and properties of the CPEs were confirmed by SEM, XRD, DSC, TGA, electrochemical impedance spectroscopy and linear sweep voltammetry. The TPU electrospun membrane as the skeleton can improve the mechanical properties of the CPEs. In addition, SiO2 particles can suppress the crystallization of PEO. The results show that the TPU‐electrospun‐membrane‐supported PEO electrolyte with 5 wt% SiO2 and 20 wt% LiTFSI (TPU/PEO‐5%SiO2‐20%Li) presents an ionic conductivity of 6.1 × 10−4 S cm−1 at 60 °C with a high tensile strength of 25.6 MPa. The battery using TPU/PEO‐5%SiO2‐20%Li as solid electrolyte and LiFePO4 as cathode shows an attractive discharge capacity of 152, 150, 121, 75, 55 and 26 mA h g−1 at C‐rates of 0.2C, 0.5C, 1C, 2C, 3C and 5C, respectively. The discharge capacity of the cell remains 110 mA h g−1 after 100 cycles at 1C at 60 °C (with a capacity retention of 91%). All the results indicate that this CPE can be applied to all‐solid‐state rechargeable lithium batteries. © 2018 Society of Chemical Industry

“…Some reports approved that there are significantly improved performances of LIBs due to ionic liquids incorporation in polymer electrolyte membranes. Several researches also have succeeded to study the effects of ionic liquids plasticization of LIBs performances [3,13,22]. The properties needed as electrolyte are negligible vapor point, large liquid-phase temperature interval, nonflammable, good thermal stability and elevated electrochemical stability [28][29].…”

Lithium-ion batteries (LIBs) are favorable power source devices at the last two decades, owing to high energy density, rechargeable, long life cycle, portable, safe, rechargeable, good performance and friendly environment. To support their development, in this research has been successfully prepared polymer electrolyte membrane, a main component of LIBs, based on 1-ethyl-3-methylimidazolium acetate ([EMIm]Ac) ionic liquid-plasticized methyl cellulose/lithium perchlorate (MC/LiClO4).[EMIm]Ac ionic liquid was easy synthesized by metathesis reaction between 1-ethyl-3-methylimidazolium bromide ([EMIm]Br) ionic liquid and potassium acetate (CH3COOK) at ambient temperature, for 1 hour.[EMIm]Ac ionic liquid was functional groups analyzed with Fourier Transform Infra-red (FT-IR) and structural analyzed with 1 H-Nuclear Magnetic Resonance (NMR) and 13 C-NMR.[EMIm]Ac ionic liquidplasticized MC/LiClO4 biopolymer electrolyte membrane was prepared by casting solution, with [EMIm]Ac ionic liquid content, 0, 5, 10, 15, 20, 25, and 30% (w/w). Effect of 15% (w/w) [EMIm]Ac ionic liquid incorporation to MC/LiClO4 showed the best condition and selected as the optimum condition with conductivity, tensile strength, elongation break, and thermal stability of 9.160×10 -3 S.cm -1 , 24.19 MPa, 36.43%, ~256 and ~370 ºC, respectively. These results confirm that [EMIm]Ac ionic liquid can plasticize biopolymer electrolyte membranes of MC/LiClO4 to be appealing performances to fulfill the LIB's separator requirement.

In this present study, we have studied the relaxation behaviour and dynamics of charge carriers in poly(ethylene oxide; PEO)/poly(methyl methacrylate; PMMA) blend with potassium based iodide–triiodide redox couple as polymer solid electrolyte dispersed with different concentration of ZnO nanorods as fillers. Various composition of potassium iodide (KI)‐based nanocomposite (PEO/PMMA/KI/I2/x wt% ZnO nanorods, x = 0, 2, 4, 6, 8, and 10) polymer solid electrolytes (NCPSEs) films were prepared by solution casting technique. Structural properties of the prepared solid electrolytes are studied by X‐ray diffraction and Fourier transform infrared spectroscopy. Among the prepared NCPSEs, 6 wt% sample of solid electrolyte showed high conductivity of 4.698 × 10−5 S/cm. The relaxation and dynamics of charge carriers are studied by analyzing complex conductivity and dielectric permittivity through power law along with the contribution of electrode polarization and Havriliak–Negami formalism, respectively, for the prepared polymer solid electrolytes to find out their usefulness for dye‐sensitized solar cell applications. © 2018 Society of Plastics Engineers POLYM.
