N2 - Ion conduction process is highly dependent on the synthesis and type of polymer salt composite. Composites are synthesized using low melting poly(ethylene oxide) (PEO) salts (NH4I and KBr) loaded with 10 wt% treated silica as passive filler. Highest ionic conductivity of ≈10−3 S cm−1 with least bulk resistance is obtained from PEO–NH4I (20%) composite consisting of treated silica as filler. The aim of the present article resides in the selection and usage of salt effectively wherein highly conductive (like PEO–NH4I-treated SiO2) and highly dielectric (like PEO–KBr-treated SiO2) films can be utilized as per the needs of application. The novelty of the research work is imbibed in the long-term endurance analyses of such composites for 2000 h. Addition of silica is reported to significantly enhance the cyclability of PEO–ammonium salt based electrolyte significantly up to 2000 h. Detailed study is carried out in terms of long-term analyses and correlated with SEM morphology.
