- Abstract
- The effect of treating a metal lithium surface with 1 M LiN(CF3SO2)2 solution in 1,3-dioxolane/1,2-dimethoxyethane (2:1) mixture on the resistance of the lithium/polymer and lithium/nanocomposite electrolyte based on the ionic liquid 1-ethyl-3-methylimidazolium tetrafluoroborate was studied. It has been shown that “liquid-phase therapy” reduces the resistance at the Li/electrolyte interface by 2.5 times at room temperature and expands the operating temperature range to –30°C. The introduction of TiO2 nanoparticles into the polymer electrolyte, along with “liquid-phase therapy” of both the cathode and the Li-anode, provides a high and stable discharge capacity of the Li//LiFePO4 battery for 100 charge-discharge cycles.
