Nanocomposite Polymer Gel Electrolyte Based on TiO₂ Nanoparticles for Lithium Batteries.

ABSTRACT: In this article, the specific features of competitive ionic and molecular transport in nanocomposite systems based on network membranes synthesized by radical polymerization of polyethylene glycol diacrylate in the presence of LiBF₄, 1-ethyl-3-methylimidazolium tetrafluoroborate, ethylene carbonate (EC), and TiO₂ nanopowder (d~21 nm) were studied for ¹H, ⁷Li, ¹¹B, ¹³C, and ¹⁹F nuclei using NMR. The membranes obtained were studied through electrochemical impedance, IR-Fourier spectroscopy, DSC, and TGA. The ionic conductivity of the membranes was up to 4.8 m Scm^-1 at room temperature. The operating temperature range was from -40 to 100 °C. Two types of molecular and ionic transport (fast and slow) have b
