Abstract

Ionic liquid-based poly(vinyl alcohol) (PVA) proton-conducting polymer electrolytes are prepared using solution casting technique. The effect of adding 1-butyl-3-methylimidazolium iodide (BmImI) ionic liquid into PVA-ammonium acetate polymer system is investigated in this work. Ionic conductivity of polymer electrolytes is increased by two orders of magnitude upon inclusion of 70 wt% of BmImI. Addition of ionic liquid reduces the glass transition temperature and crystallinity of polymer electrolytes. Electrical double-layer capacitors (EDLCs) are assembled using dip-coating technique. The electrochemical properties of fabricated EDLCs are analysed using cyclic voltammetry.
