英文摘要	The open characteristic of lithium-O-2 batteries results in issues of drying out and explosion hazards. Ionic liquids (Ms) are reliable in terms of these issues because they have near-zero vapor pressure and are generally nonflammable. However, the rate capability of Li-O-2 batteries with ionic liquids is currently limited to 0.05-0.5 mA/cm(2) owing to poor oxygen solubility, poor wettability with solid cathode, and high viscosity. Herein, an ether-functionalized ammonium ionic liquid Li-O-2 battery sustains repeated cycling at 5.0 mA/cm(2) (80 degrees C), enhancing 1 order of magnitude in rate capability. The unprecedented high rate is attributed to the improved 3-phase interfacial properties (mainly O-2 diffusion and wettability), LiOHbased cycling process at the cathode, and stable passivation film on the Li anode. Our results demonstrate that a substantial improvement in rate capability can be achieved by coordinating cathode/IL electrolyte/anode interface and reaction mechanism. The high rate capability is an encouraging prospect for the operating conditions of electric vehicles under high power output (discharging) and rapid state-of-charge.
