“…In the composite nanobers, the cross-linked component hindered the crystallization of PVDF-HFP, which improved the thermal stability of the CGPE membranes to some extent. 24 In addition, the UV cured process of cross-linking agent and PEGMA did not affect the thermal stability of the electrolytes. The good thermal stability of the CGPE membranes guarantees the safety of the battery at high temperatures.…”

A deformable and flexible cross-linked composite gel polymer electrolyte (CGPE) membrane, blended with an ionic liquid (IL) diluent, was successfully prepared for lithium-ion batteries. Herein, a cross-linked composite gel polymer electrolyte membrane in the presence of an IL resulted in the formation of a solid-like, elastic gel directly within the poly(vinylidene fluoride-co-hexafluoropropylene) electrospun skeleton via in situ UV-induced cross-linking of poly(ethylene glycol)methyl ether methacrylate (PEGMA), pentaerythritol tetraacrylate, and PEGMA monomers. The CGPE membrane exhibited significantly improved film flexibility and prevented liquid leakage while maintaining some advantageous features such as good liquid retention, high ionic conductivity, and good thermal stability. Moreover, the CGPE-3 exhibited the best performance, with a wide electrochemical potential window of up to 5.0 V vs. Li + /Li and a high ionic conductivity of 1.7 Â 10 À3 S cm À1. The Li/CGPE/LiFePO 4 cells with CGPE-3 exhibited stable electrochemical performance and yielded specific capacities of 160, 150, 136, 122, and 91 mA h g À1 at 0.1, 0.2, 0.5, 1.0, and 2.0C rates, respectively; moreover, they retained their properties well after 100 cycles for each rate. These solid-like gel polymer electrolyte membranes with excellent properties represent a very promising material for high-performance lithium-ion batteries with improved safety and reliability.

“…On the other hand, the absorption peak of epoxide group indicates that lithium hydroxide does not damage the structure of oligomer during the neutralization process. Figure b shows the characteristic spectra of α‐ and γ‐ phases of PVdF observed in the range of 500–1600 cm −1 which have reported as follows: α‐phase (TGTG−); 509 cm −1 (CF 2 ‐bending), 1070 cm −1 (CH 2 wagging) and γ‐phase (TTTGTTTG−); 841 cm −1 (CH out‐of‐plane deformation and CH 2 rocking), 881 cm −1 (CF 2 symmetric stretching), 1190 cm −1 (CF out‐of‐plane deformation), 1400 cm −1 (CH 2 wagging) . After ionized oligomer was introduced into PVdF, the absorption peaks of PVdF‐10 give mixed FTIR spectra of the ionized oligomer and PVdF (Figure c).…”

In this paper, a novel adhesive prepared by blending lithium‐ion functionalized epoxy resin (ionized oligomer) with poly(vinylidenedifluoride) (PVdF) is used to fabricate the cathode electrode of LiCoO2. The properties of the blending adhesive are studied by Fourier transform infrared spectroscopy, differential scanning calorimeter, and thermogravimetric analysis, and the morphology and performance of the composite cathodes are characterized by using X‐ray photoelectron spectroscopy (XPS), scanning and transmission electron microscopy, electrochemical impedance spectroscopy, and galvanostatic charge‐discharge. With the blended ionized oligomer, the crystallinity behavior of PVdF is decreased effectively, which will be beneficial to the movement of conducting ions. An appropriate amount of ionized oligomer effectively improves the conductivity and charge‐transfer capability of the cathode material. When the amount of ionized oligomer to the PVdF binder is 10 wt%, the LiCoO2‐based composite cathode delivers the highest charge−discharge capacity (178 mAh g−1) and the capacity retention is up to 82.2 % after 100 cycles.

“…The LIBs with the PMMA/PAN NF membranes as the separator exhibited excellent initial discharge capacities, as well as remarkable cycle performance, resulting from the unique electrospun core-shell structure of PMMA/PAN NF membranes. Electrospun SiO 2 /PAN [114,115], PAN/Al 2 O 3 -TEGDA-BA [116] (triethylene glycol diacetate-2-propenoic acid butyl ester (TEGDA-BA)), PAN/TEGDA-BA [117], PAN/PEO [118] (polyethylene oxide (PEO)), oxy-PAN [119] and LLTO/PAN (lithium lanthanum titanate oxide (LLTO)) [120] NF membranes were used as separators for LIBs, which showed remarkably good physical properties and electrochemical performance. The overview of electrospun fiber membranes as separators of LIBs mentioned above is presented in Table 3.…”

With global concerns about the shortage of fossil fuels and environmental issues, the development of efficient and clean energy storage devices has been drastically accelerated. Nanofibers are used widely for energy storage devices due to their high surface areas and porosities. Electrospinning is a versatile and efficient fabrication method for nanofibers. In this review, we mainly focus on the application of electrospun nanofibers on energy storage, such as lithium batteries, fuel cells, dye-sensitized solar cells and supercapacitors. The structure and properties of nanofibers are also summarized systematically. The special morphology of nanofibers prepared by electrospinning is significant to the functional materials for energy storage.
