In this work, we found that the side reactions of both the Li anode and cathode with the electrolyte can be obviously alleviated at low temperature. This favorable merit enables long cycle life of the Li-O-2 cells at low temperature. At 0 degrees C, the cells can sustain stable cycling of 279 and 1025 cycles at 400 mA g(-1) with limited capacities of 1000 and 500 mA h g(-1), respectively. Even at -20 degrees C, the cell can be stably cycled for 83 cycles at 200 mA g(-1) with a limited capacity of 500 mA h g(-1).
