Narrow operational voltage window can be considered as one of the greatest limitations for aqueous polymer electrolytes. It has been reported that this window could be made wider by using hydrogel electrolytes employing alkali metal salts as ion source [1, 2]. Using freeze-thaw hydrogel preparation method we have synthesized four electrolytic polyvinyl alcohol (PVA) hydrogels. Ion conductivity of these hydrogels has been achieved using H3PO4, KOH, Na2SO4 and K2SO4.
