“…Due to these advantages, it is being used in many electrochemical cells and sensors. [32,33] A similar kind of work was done by Saleem et al in which the electrochemical properties of Zn/ PVA-KOH-H 2 O-Iodine/C cell were studied for fixed concentration ratio of active materials. [32] These kinds of cells were found to be rechargeable and having good stability.…”

“…[30] In last few years, organic semiconductor based electrochemical cells have been fabricated and investigated. [31][32][33][34] Among them, organic orange dye (OD) based electrochemical cells are more important [31,34] as they show good electrical conductivity in distilled water. [35] OD is stable at room temperature and has excellent solubility in H 2 O.…”

Polyethylene glycol (PEG) and polyvinyl alcohol (PVA) were used as a zinc electrode binder at different concentrations to enhance the electrochemical behavior of zinc electrodes for nickel-zinc (NiZn) batteries. ZnO powders synthesized by mechanochemical and hydrothermal precipitation methods were mixed with lead oxide, calcium hydroxide and binder to prepare zinc electrodes in pouch cell NiZn batteries. Scanning Electron Microscopy (SEM) and X-Ray Diffraction (XRD) analysis reveal that initial morphology of zinc electrode changes drastically regardless of the binder type and its loading after charge/discharge process, and even the charge/discharge process is not complete. The results show that the presence of PEG causes better discharge capacity compared to that of PVA as a binder. Zinc electrode prepared using commercial ZnO powder and 3 wt.% PEG gives the optimum discharge capability, with a specific capacity of approximately 311 mAhg -1 , while zinc electrodes prepared using ZnO powder synthesized from ZnCl2 and Zn(NO3)2.6H2O and 6 wt.% PEG exhibit high specific energy of 255 and 275 mAhg -1 , respectively. The results suggest a relationship between binder loading and battery capacity, but in-situ analysis of microstructural evolution of zinc electrode during charge/discharge process is needed to confirm this relationship.

“…Li rechargeable cells have received a tremendous attention for many years but their hazardous nature and the increasing cost have been well recognized now. As a result, attention of the scientific community has been focussed towards alternative anode materials such as Zn, Mg and Na (Sheha, 2013;Saleem, 2009). In this study, it was aimed to investigate the effect of the conductivity of the electrolyte on the performance of Zn rechargeable cells.…”

Gel polymer electrolytes (GPEs) have been extensively considered for various applications such as primary and rechargeable cells, super capacitors and electrochromic devices. Various strategies have been adopted to enhance their properties so as to develop efficient and effective devices. One such method is to increase the ionic conductivity of the electrolyte. In this study, attempts were made to study the variation of ionic conductivity with salt concentration of a GPE and to evaluate the dependence of performance on conductivity in a rechargeable cell. The composition was optimized by varying the salt concentration. The highest room temperature conductivity of 4.46×10 -3 Scm -1 was obtained with the composition 50 PVdF : 100 EC : 100 PC : 80 ZnTf (by weight). The maximum ionic transference number was also obtained with this composition and it was 0.97. Four different cells were fabricated with four different salt concentrations and the best performance was observed with the cell having the GPE of the highest conductivity. This clearly proves that performance of the device depends on the conductivity of the electrolyte.
