Exploring lithium ion transport efficiency in modified MgO-supplementary PVdF-HFP nanocomposite polymer electrolytes: Intuitions from Electrochemical study

Modified MgO (mMgO) incorporated thin film poly (vinylidenefluoride-co-hex
afluoropropylene) (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, T g, ∆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 yLi
ClO4 + 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
