“…Diverse methods, such as plasticization, incorporation of nanofillers, and copolymerization, have been utilized to achieve enhanced ionic conduction and increased stability in polymer electrolytes. These efforts have led to the emergence of a specialized category of polymer electrolyte termed 'composite polymer electrolyte (CPE)' [8]. Enhancing the electrical conductivity and strengthening the thermal, mechanical, and electrochemical stability of polymer electrolyte films often involves dispersing them with ceramic inorganic/organic fillers as a common practice.…”

Free standing nanocomposite polymer electrolytes (NCPEs) based on the polymer host poly(vinyl) chloride (PVC) were successfully prepared using the solution casting technique. Lithium nitrate (LiNO3) and nano-sized silica (SiO2) (< 100 nm) were employed as the electrolyte and filler, respectively. Impedance studies revealed a maximum ionic conductivity value of 1.226 x 10− 4 S/cm at room temperature for the PVC/LiNO3 with 5 wt.% nano-SiO2. X-ray diffraction (XRD) analysis verified the sample's amorphous nature. Dielectric permittivity and relaxation time values were consistent with impedance results. Additionally, parameters such as diffusion coefficient, mobile concentration, and mobility were evaluated for the prepared samples. Differential scanning calorimetry (DSC) studies confirmed a change in glass transition temperature (Tg) of PVC/LiNO3/SiO2 sample. The scanning electron micrograph (SEM) images revealed a honey-comb morphology, indicating ease of Li+ ion transportation.
