摘要

Modified MgO (mMgO) incorporated thin film poly (vinylidenefluoride-co-hexafluoropropylene) (PVdF-HFP) nanocomposite polymer membrane (TFPM) have been fabricated by simple phase inversion technique. mMgO nanofiller (8wt. % loading) treated PVdF-HFP polymer matrix improved in porosity (ρ) up to 81%. The TFPM have better mechanical strength (2380 kPa) than untreated polymer membrane (1310 kPa). Thermal properties of 8wt.% mMgO loaded TFPM achieved better results in Tm, Tg, ∆Hm and Xc values such as 141.7 °C, − 43.3 °C, 23.84 J.g−1 and 22.76% than other (≤ 6wt. % loading) TFPMs. TFPMs were immersed in yLiClO4 + EC/DMC (1:1 by volume) separately to form a thin film nanocomposite polymer membrane electrolyte (TFPE). Lithium ion conductivity of TFPE was obtained 3.1 × 10−3 S cm−1 and the Li+ transference number was found to be a maximum of ca. 0.79. The finding TFPE [MCMB||TFPE|| LiCoO2] provided an avenue for LIBs, which can be a potential candidates for energy storage devices technology.
