Abstract
A free standing electrolyte film containing poly glycidyl methacrylate (PGMA) as polymer host, lithium perchlorate (LiClO4) as charge carrier and ethylene carbonate (EC) as plasticizer were successfully prepared with solution casting technique. Nuclear magnetic resonance spectroscopy (NMR) was used to investigate the chemical structure of the polymer. The analyses of polymer electrolytes were performed by impedance spectroscopy (EIS), linear sweep voltammetry (LSV) and fourier transform infrared spectroscopy (ATR-FTIR). The solid polymer electrolyte exhibited the highest conductivity at room temperature and 373Â K with the values of 3.4Â ÃÂ 10â4Â SÂ cmâ1 and 1.2Â ÃÂ 10â3Â SÂ cmâ1 at 80Â wt.% of EC, respectively, in the presence of 80Â wt.% of EC. FTIR spectroscopy analysis confirmed the interaction between lithium salt and oxygen atoms in polymer host in the presence of EC. Moreover, the electrolytes containing EC showed good electrochemical stability (â1500 to 3000) mV which reveals the potential of this polymer electrolyte for photoelectrochemical cell (PEC) application.
