“…This behavior has been observed in other polymerefiller systems, e.g. EO/PO/TiO 2 [25] and LDPE/ultrasil [26]. The decrease in I 3 and, consequently, the free volume concentration may also be attributed to the restriction of polymer chain mobility due to the presence of higher concentration of TiB 2 .…”

The hybrid polymer nanocomposites based on poly(vinylidene fluoride-co-hexaflouro propylene) (PVdF-HFP) as a host matrix, propylene carbonate as the plasticizer, and surface modified and unmodified TiO 2 nanoparticles as fillers for dye-sensitized solar cell applications have been prepared using a solvent casting technique. The surface of TiO 2 was modified using aminopropyltrimethoxysilane (APS), and its organic functional groups on TiO 2 were confirmed by Fourier transform infrared (FTIR) spectroscopy. The PVdF-HFP membranes were characterized by FTIR, wide-angle X-ray diffraction (WAXD), differential scanning calorimetry (DSC), dynamic mechanical analysis (DMA), atomic force microscopic (AFM), and ultraviolet-visible (UV-Vis) spectroscopic techniques. It was found a new interaction of APS molecules on TiO 2 surface with matrix as well as electrolyte salt. The experimental observations indicated a noticeable improvement in ionic conductivity of modified TiO 2 of about 6.7×10 −4 S/cm when compared with unmodified counterpart (TiO 2 ) as the filler within PVDF-HFP matrix. The solid state dye-sensitized solar cell has been fabricated by using silanemodified TiO 2 /PVdF-HFP nanocomposite electrolyte and eosin-Y as sensitizer, and its photoconversion efficiency is measured about 1.47 %.

“…Raghavan et al [143] have prepared a series of nanocomposite polymer electrolytes comprising nanoparticles of BaTiO 3 , Al 2 O 3 or SiO 2 by electrospinning technique. The effect of these ferroelectric ceramic fillers appeared to be highly dependent on the nature of the salt used in the PEO-based systems, with LiClO 4 showing the most dramatic effects [144] .

This paper reviews the recent developments and the characteristics of polymeric separators used for lithium ion batteries. According to the structure and composition of the separators, they are broadly divided into four types: (1) polyolefin microporous separator, (2) heterochain polymer microporous separator, (3) polymer electrolyte and (4) non-woven separator. Specially, polymer electrolyte was defined as one category of separators for the convenient description in this review, which features intermediate between the two electrodes and possesses transport properties comparable with the separaor in liquid LIB. For each category, the structure, characteristics, modification, and performance of separators are described. Finally, the guidelines for further improvements in this research are outlined.
