“…For the present work, we have adopted one of the above techniques, namely blending, because of the ease of preparation and easy control of physical properties within the compositional regime. The inherent merits of using blend-based polymer electrolytes have been exemplified by several research groups [31,32], detailed studies of the blend-based polymer electrolytes can furnish valuable information on the relative importance of various factors, which affect the electrical, thermal and mechanical properties of the polymer blend electrolytes.…”

“…To address these issues, various strategies such as blending, preparing block copolymers and adding ceramic fillers have been reported to resolve the disadvantages of pure PEO. Ceramic fillers can clearly improve the performance of polymer electrolytes and have been illustrated in previous studies . The ceramic fillers can both reduce the degree of crystallinity of PEO and form a network structure in the matrix, leading to high ionic conductivity and superior mechanical stability of PEO‐based electrolytes.…”

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

“…Polymer electrolytes are supposed to have a comparative ionic conductivity to that of liquid electrolytes. As the polymer electrolytes exhibit an ionic conductivity of the order of 10 −4 S cm −1 , at room temperature, various approaches such as the preparation of solid polymer electrolytes (polymer blend [6][7][8] and copolymer [9]), gel polymer electrolyte (plasticizer [8,10], ionic liquids [11,12], and coupling agent [13]) and composite polymer electrolyte (inorganic filler [14] and clay [15]) have been reported.…”

Plasticized polymer electrolytes comprising of ethylene carbonate as the plasticizing agent in poly (vinyl chloride) [PVC]-poly (butyl methacrylate) [PBMA] blended polymer electrolytes were prepared by solution casting technique.Complex formation, structural elucidation, conductivity, dielectric parameters ( ′, ″, M′, and M″), thermal stability, and surface morphology are brought out from FTIR, XRD, ac impedance analysis, dielectric studies, thermogravimetry/ differential thermal analysis, and scanning electron microscopic studies, respectively. Polymer electrolytes are found to exhibit higher ionic conductivity at higher concentration of plasticizer at the cost of their mechanical stability. Conductivity of 1.879 × 10 −4 S cm −1 is exhibited by the polymer electrolyte consisting of 69% of plasticizer with appreciable thermal stability up to 523 K. Temperature and frequency dependence of conductivity is found to follow Vogel Tammann Fulcher relation and Jonscher power law, respectively. Real and imaginary parts of dielectric constants are found to decrease with increase in frequency which could be due to the electrode polarization effect.
