| Abstract: | Polyvinyl alcohol (PVA) alkaline gel polymer electrolyte (GPE) membranes were successfully prepared by a solution-casting technique and applied in secondary Ni/Zn batteries. Their electrochemical stabilities had been investigated by cyclic voltammograms (CV) and Raman spectra. The results indicated that the GPE membranes had promising electrochemical stabilities. Compared with the one employing a 5 mol/L KOH aqueous solution as the electrolyte, the Ni/Zn secondary battery with the PVA alkaline gel polymer as the electrolyte had longer cycle life. |
