(a) First charge–discharge curves of lithium-oxygen (Li-O2) cells at a current density of 300 mA g−1 and a specific capacity limit of 3,000 mAh g−1. (b) CV of the three kinds of cathode in Li-O2 cells at a constant scan rate of 0.1 mV s−1. (c) The rate capability of the Li-O2 cells with the three kinds of cathode at the current density of 500 mA g−1. (d) The rate capability of the Li-O2 cells with the three kinds of cathode at the current density of 1,500 mA g−1. Inset in d is the enlarged discharge profile of the Li-O2 cells with conventional Super P carbon (SP) cathode.
