“…Hassan et al [ 11 ] reported the ionic conductivities of the PEO-KOH-H 2 O ASPEs reaching the level of 10 −5 S·cm −1 with using in Ni-MH batteries. Chandrasekaran et al [ 12 ] prepared an ASPE based on PEO + NaClO 3 for using in Ni-MH batteries, and the ionic conductivity reached 10 −4 S·cm −1 . Although the PEO-based ASPEs could form a dimensionally stable membrane, but the conductivity was still too low for application in electrochemical devices [ 13 ].…”

Natural bamboo charcoal (BC) powder has been developed as a novel filler in order to further improve performances of the polyvinyl alcohol (PVA)-based alkaline solid polymer electrolyte (ASPE) by solution casting method. X-ray diffraction patterns of composite polymer electrolyte with BC revealed the decrease in the degree of crystallinity with increasing content of BC. Scanning electron microscopy images showed pores on a micrometer scale (average diameter about 2 μm) distributed inside and on the surface of the membranes, indicating a three-dimension network formed in the polymer framework. The ionic conductivity was measured by the alternating-current (AC) impedance method, and the highest conductivity value of 6.63 × 10−2 S·cm−1 was obtained with 16 wt % of BC content and mKOH:mPVA = 2:1.5 at 30 °C. The contents of BC and KOH could significantly influence the conductivity. The temperature dependence of the bulk electrical conductivity displayed a combination of Arrhenius nature, and the activation energy for the ion in polymer electrolyte has been calculated. The electrochemical stability window of the electrolyte membrane was over 1.6 V. The thermogravimetric analysis curves showed that the degradation temperatures of PVA-BC-KOH ASPE membranes shifted toward higher with adding BC. A simple nickel-hydrogen battery containing PVA-BC-KOH electrolyte membrane was assembled with a maximum discharge capacity of 193 mAh·g−1.

“…This has been referred to as Optimum Conducting Composition (OCC). The increase in conductivity is due to the increase in degree of amorphousity, which can be explained by the various models [3][4][5]. FTIR is also a powerful technique to confirm the complexation between polymer and salts.…”

“…Ion conduction in polymers was reported for the first time in 1973 and the first practical SPE battery based on 'Poly (ethylene oxide) (PEO) -Li + -ion salt complex' was demonstrated in 1979 [7]. Since then, a large number of solid polymer electrolytes (SPEs) and nanocomposite polymer electrolytes (NCPEs) have been reported [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. SPE/ NCPE films are prepared usually by solutioncast method.…”

Ion transport properties of hot-pressed Solid Polymer Electrolyte (SPE) membranes: (1-x) PEO: x NaHCO 3 , where x = 0 -50 wt. (%), has been reported. SPE films have been casted using a hot-press technique in place of the traditional solution cast method. A conductivity enhancement of the two orders of magnitude was achieved in SPE film: 70PEO: 30NaHCO 3 and this composition has been referred to as Optimum Conducting Composition (OCC). Materials characterization was done with the help of FTIR and DSC techniques. The ion transport behavior in SPE membranes have been discussed on the basis of experimental measurements on their ionic conductivity ( ) and other parameters. The temperature dependent conductivity studies have also been done to compute the activation energy (E a ) values by least square linear fitting of 'log -1/T' Arrhenius plots.

The thin-film solid polymer electrolyte based on polyethylene oxide (PEO) with sodium chlorite (NaClO 3 ) has been prepared by a solution-cast technique. The electrolyte was characterized by X-ray diffraction (XRD), infrared (IR), cyclic voltammetry, alternating current conductivity, and Wagner's polarization studies. The complexation of NaClO 3 with PEO was confirmed through the XRD and IR studies. The transference number measurement has shown that the ion transport is predominant over electrons in the polymer electrolytes (t ions ≈0.94). The conductivity enhancement was observed in the case of the PEO/NaClO 3 system with the addition of plasticizers (low-molecular-weight polyethylene glycol, organic solvents propylene carbonate and dimethyl formamide. Cyclic voltammetry analysis showed the stability and redox character of the electrolyte and electrode. Finally, polymer electrolyte systems were examined by electrochemical cell studies using V 2 O 5 and composite V 2 O 5 cathode at temperature of 35°C. Overall, the plasticized electrolyte shows a better electrochemical performance, and a higher discharge capacity was observed in composite V 2 O 5 -based cells over V 2 O 5 -based cells.
