“…One of most widely used methods to prepare polymer electrolytes is the immobilization of 1 M lithium hexafluorophosphate (LiPF 6 within ethylene carbonate (EC)/dimethyl carbonate (DMC) in electrospun fiber membranes. 27 An increased interest in improving the performance of Li-ion polymer batteries has resulted from the rapid expansion in the industrial demand for these batteries. Improved performance has relied on gel polymer electrolytes (GPEs), such as those based on electrospun PVDF-graft-poly-tert-butylacrylate (g-tBA) nanofiber membranes.…”

“…28 Electrospun PVDF-PHFP/silica composite nanofiberbased polymer electrolytes were comparatively better than those prepared through the direct addition of silica. 27 Dyesensitized solar cell (DSSC) devices also use polymer electrolytes based on electrospun PVDF-PHFP nanofibers and show power conversion efficiency greater than 5%. 29 …”

Electrospinning of nanomaterial composites are gaining increased interest in the fabrication of electronic components and devices. Performance improvement of electrospun components results from the unique properties associated with nanometer-scaled features, high specific surface areas, and light-weight designs. Electrospun nanofiber membrane-containing polymer electrolytes show improved ionic conductivity, electrochemical stability, low interfacial resistance, and improved charge-discharge performance than those prepared from conventional membranes. Batteries with non-woven electrospun separators have increased cycle life and higher rate capabilities than ones with conventional separators. Electrospun nanofibers may also be used as working electrodes in lithium-ion batteries, where they exhibit excellent rate capability, high reversible capacity, and good cycling performance. Moreover, the high surface area of electrospun activated carbon nanofibers improves supercapacitor energy density. Similarly, nanowires having quasi-one-dimensional structures prepared by electrospinning show high conductivity and have been used in ultra-sensitive chemical sensors, optoelectronics, and catalysts. Electrospun conductive polymers can also perform as flexible electrodes. Finally, the thin, porous structure of electrospun nanofibers provides for the high strain and fast response required for improved actuator performance. The current review examines recent advances in the application of electrospinning in fabricating electronic components and devices.

“…The addition of ceramic nanoparticles, such as TiO 2 (Croce et al 1998(Croce et al , 1999Jeon et al 2006), SiO 2 (Raghaven et al 2008;Capiglia et al 1999), Al 2 O 3 , (Bruce 2008;Krawiec et al 1995;Jayathilaka et al 2002) Fe 3 O 4 (Reddy et al 2006) and S-ZrO 2 (Croce et al 2006;Panero et al 2007) to polymer electrolytes has been shown to improve ionic conductivity, and mechanical and electrochemical properties of the polymer electrolyte. The increase in ionic conductivity in composite electrolytes (CPEs) with inert fillers has been attributed to the nanoparticles acting as solid plasticizers, disturbing polymer crystallization.…”

From aqueous liquid electrolytes for lithiumair cells to ionic liquid electrolytes that permit continuous, high-rate cycling of secondary batteries comprising metallic lithium anodes, we show that many of the key impediments to progress in developing next-generation batteries with high specific energies can be overcome with cleaver designs of the electrolyte. When these designs are coupled with as cleverly engineered electrode configurations that control chemical interactions between the electrolyte and electrode or by simple additives-based schemes for manipulating physical contact between the electrolyte and electrode, we further show that rechargeable battery configurations can be facilely designed to achieve desirable safety, energy density and cycling performance.

“…There are many ways to produce GPEs such as phase inversion method, γ-ray irradiation method, solvent casting technique, thermally induced phase separation technique, and electrospinning technique. [6][7][8] In these methods, electrospinning technique which made the solution of polymer into lots of uniform and slender nanofibers under high voltage is a simple, controllable and efficient approach. Thermoplastic polyurethane (TPU) contains two-phase microstructure which are soft segments and hard segments.…”

A novel high-performance gel polymer electrolyte (GPE) based on poly(vinylidene fluoride) (PVDF), thermoplastic polyurethane (TPU) and polystyrene (PS) has been prepared. Its characteristics are investigated by scanning electron microscopy (SEM), thermal analysis (DSC), universal testing machines (UTM), galvanostatic charge-discharge and electrochemical impedance spectroscopy. The GPE based on TPU/PVDF/PS (10 wt.%) show a high ionic conductivity of 5.28 × 10 -3 S cm -1 with the electrochemical stability window of 5.0 V. In addition, its first charge-discharge capacity reached to 169.5 mAh g -1 , high mechanical strength and stability to allow safe operation in rechargeable lithium ion polymer batteries.
