Narrow operational voltage window can be considered as one of the greatest limitations for aqueous polymer electrolytes.Using freeze-thaw hydrogel preparation method we have synthesized wider potential windowelectrolytic polyvinyl alcohol (PVA)/Na2SO4and PVA/K2SO4electrolytes.Supercapacitors(SC) have been assembled using novel porous polyisoprene and carbon black composite electrodes. Our SC exhibit pressure sensitive properties therefore this effect is deeper explored here, giving explanation for capacitance increase during pressure application. It is found that up to 2 MPa the capacitance increases due to greater interface between electrode and electrolyte
