“…The reduction of PEO crystallinity arises from random distribution of NiO filler which may introduce the topological disorder in the electrolyte. The reduction of crystallinity will produce more amorphous phase in the system which makes the electrolyte more flexible, resulting in increase of the segmental motion of the polymer [26]. Thus, the conductivity of PEO-based polymer electrolytes increases with wt.% NiO which is supported by the XRD results.…”

Composite polymer electrolyte films comprising polyethylene oxide (PEO) as the polymer host, LiClO 4 as the dopant, and NiO nanoparticle as the inorganic filler was prepared by solution casting technique. NiO inorganic filler was synthesized via sol-gel method. The effect of NiO filler on the ionic conductivity, structure, and morphology of PEO-LiClO 4 -based composite polymer electrolyte was investigated by AC impedance spectroscopy, X-ray diffraction, and scanning electron microscopy, respectively. It was observed that the conductivity of the electrolyte increases with NiO concentration. The highest room temperature conductivity of the electrolyte was 7.4×10 −4 S cm −1 at 10 wt.% NiO. The observation on structure shows the highest conductivity appears in amorphous phase. This result has been supported by surface morphology analysis showing that the NiO filler are well distributed in the samples. As a conclusion, the addition of NiO nanofiller improves the conductivity of PEO-LiClO 4 composite polymer electrolyte.

“…Thus, it disturbed the ionic mobility as it congested the ionic migration in the segmental polymer chain. As a consequence, the ionic conductivity decreases after the optimum salt loading in MG49-LiBF 4 [25]. The effects of this phenomenon has been proven and discussed in the previous section.…”

Abstract:The studies of rubber-polymer blends as solid polymer electrolyte for electrochemical devices application have been investigated. The electrolyte films were prepared by solution casting technique. The effect of poly(methyl methacrylate) (PMMA) and lithium tetrafluoroborate (LiBF 4 ), salt concentration on chemical interaction, ionic conductivity, structure and morphology of 49% poly(methyl methacrylate)-grafted natural rubber (MG49) have been analyzed by using fourier transform infrared spectroscopy (FT-IR), electrochemical impedance spectroscopy (EIS), x-ray diffraction (XRD) and scanning electron microscopy (SEM). Infrared analysis showed that the interaction between oxygen atoms and lithium ion occurred at ether (C-O-C) and carbonyl (C=O) group in the MMA host. The highest ionic conductivity for blended MG49-PMMA films is 8.3 10 -6 S cm -1 as compared to MG49 electrolyte with 9.6 10 -10 S cm -1 at 25 wt. % LiBF 4 . The structural analysis showed the reduction of MMA crystallinity phase at the highest conductivity for both systems. Meanwhile, morphological analysis shows that recrystallization of LiBF 4 salts have occurred in the electrolyte system after the optimum conductivity.

“…However, the band is split into two at 2918 and 2884 cm -1 corresponding to asymmetric and symmetric CH 2 stretching, respectively [27]. Other bands at 1490, 1368-1342 and 1113 cm -1 are CH 2 scissoring, CH 2 wagging, C-O-C stretching modes [28,29]. The existence of chemical interchain between PEO with PI was proved by FTIR study.…”

Abstract. This paper deals with the synthesis and characterization of a new type of anhydrous ionic conducting lithium doped membranes consist of polyimide (PI), poly (ethylene oxide) (PEO) and lithium trifluoromethanesulfonate (LiCF 3 SO 3 ) for solid polymer electrolyte (SPE). For this purpose, different molar ratios of lithium salt (Li-salt) solution are added into poly (amic acid) (PAA) intermediate prepared from the reaction of 3,3!,4,4!-benzophenon tetracarboxylic dianhydride (BTDA) and 4,4!-oxydianiline (ODA). PEO is incorporated into PAA since it forms more stable complexes and possess high ionic conductivities. Then, Li-salt containing PAA solutions are imidized by thermal process. The effect of interaction between host polymer and Li-salt is characterized by FT-IR (Fourier Transform Infrared) spectroscopy and SEM (scanning electron micrsocopy). The conductivities of Li-salt and PEO containing PI composite membranes are in the range of 10 -7 -10 -5 S·cm -1 . The conductivity increases with incorporation of PEO. Thermogravimetric analysis results reveal that the PI/PEO/LiCF 3 SO 3 composite polymer electrolyte membranes are thermally stable up to 500°C.
