The electrochemical performance of the nanocomposite solid polymer electrolyte (NSPE) films comprising poly (ethylene oxide) (PEO) and poly(methyl methacrylate) (PMMA) blend as host polymer matrix, lithium perchlorate (LiClO4) as dopant ionic salt, and nanosize SiO2, Al2O3, ZnO and SnO2 particles as inorganic nanofillers have been investigated by employing the electrochemical analyzer and precision LCR meter. The linear sweep voltammetry (LSV), cyclic voltammetry (CV), chronoamperometry (CA), and electrochemical impedance spectroscopy (EIS) measurements of the NSPE films have been performed with symmetrical cells of these films at ambient temperature. It is found that these materials have a conduction stability voltage of about 3 V, excellent reversibility performance over 6 V range, the ionic transference number close to unity ( > 0.98), and significant value of ionic conductivity ( similar to 10(-5) S cm(-1)) confirming their suitability as electrolyte/separator for the devel- opment of solid-state rechargeable lithium-ion batteries (LIBs). All these electrolyte materials exhibit negative resistance region above the stability voltage in their LSV plots. The electrochemical parameters and the negative resistance properties of these NSPEs are found greatly affected by the crystallinity, particle size, and dielectric constant of the nanofillers. The ionic conductivity of these NSPEs depends on the structural dynamics of inorganic nanoparticles incorporated ion-dipolar complexes of the materials.
