“…Others PMMA peaks are also observed after the addition of LiBF 4 salts in MG49-PMMA system at 29.4°, 47.6° and 48.5°. Similar to our previous study on MG49-PMMA at blend ratio (30/70) [8], a maximum ionic conductivity value still occurs due to the reduction of the PMMA peak intensity from hump shape to a broadening shape. The reduction of hump shape in Fig.…”

“…The interaction between the oxygen atoms and lithium ions of the metal salt forms a coordinate bond and generates polymer-salt complexes [5,6]. Previous studies on various MG were reported elsewhere [5,7,8]. However, MG based polymer electrolytes without plasticizers such as polypropylene carbonate (PC) and ethylene carbonate (EC) provide low ionic conductivity values.…”

“…In addition, PMMA has a polar functional group in the side chains that shows high affinity for lithium ions. The oxygen atoms in the PMMA structure will provide a coordination site for lithium ion to transport [8,12]. This coordination site acts as a stiffener that fast ion transport, occurring through a continuous conduction path that does not affect the electrochemical stability of the electrolyte [13].…”

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.

“…The porosity observed in all of the cross-sectional images when NaI was added into the polymer host may be due to the rapid evaporation of THF during the preparation of the film [34,35]. The sizes of the micro-pores are smaller at 20 wt% of NaI (Figure 6b), and this will make the ions move easily in the polymer host and leads to an increase in the ionic conductivity.…”

Abstract:Polymer electrolytes based on 90 wt% of methyl methacrylate and 10 wt% of ethyl methacrylate (90MMA-co-10EMA) incorporating different weight ratios of sodium iodide were prepared using the solution casting method. The complexation between salt and copolymer host has been investigated using Fourier transform infrared spectroscopy. The ionic conductivity and thermal stability of the electrolytes were measured using impedance spectroscopy and differential scanning calorimetry, respectively. Scanning electron microscopy was used to study the morphology of the polymer electrolytes. The ionic conductivity and glass transition temperature increased up to 20 wt% of sodium iodide (5.19 × 10) and decreased with the further addition of salt concentration, because of the crosslinked effect. The morphology behavior of the highest conducting sample also showed smaller pores compared to the other concentration. The total ionic transference number proved that this system was mainly due to ions, and the electrochemical stability window was up to 2.5 V, which is suitable for a dye-sensitized solar cell application. This sample was then tested in a dye-sensitized solar cell and exhibited an efficiency of 0.62%. OPEN ACCESSPolymers 2015, 7 267

Lithium–sulfur (Li–S) batteries are one of the most promising next‐generation energy storage systems due to their ultrahigh theoretical specific capacity. However, their practical applications are seriously hindered by some inevitable disadvantages such as the insulative nature of sulfur and Li2S, volume expansion of the cathode, the shuttle effect of polysulfides, and the growth of lithium dendrites on the anode. Of these, the polysulfide shuttle effect is one of the most critical issues causing the irreversible loss of active materials and rapid capacity degradation of batteries. Herein, modified separators with functional coatings inhibiting the migration of polysulfides are enumerated based on three effects toward polysulfides: the adsorption effect, separation effect, and catalytic effect. To solve the shuttle effect problem, researchers have replaced liquid electrolytes with solid‐state electrolytes. In this review, solid‐state electrolytes for lithium–sulfur batteries are grouped into three categories: inorganic solid electrolytes, solid polymer electrolytes, and composite solid electrolytes. Challenges and perspectives regarding the development of an optimized strategy to inhibit the polysulfide shuttle for enhancing cycle stability in lithium–sulfur batteries are also proposed.
