Here, N-doped defective carbon with trace Co （1.5 wt%） was prepared via a scalable one pot solid pyrolysis process. The sample exhibits efficient bifunctional OER/ORR activiW in alkaline, mainly ascribed to the unique micro-mesoporous structure （1-3 nm）, high population of graphitic-N doping （up to 49.0%）, abundant defects and the encapsulated Co nanoparticles with graphitized carbon. The according rechargeahle liquid Zn-air batteries showed excellent performance （maximum power density of 154.0 mWcm-2： energy density of 773Wh kg -1 at 5 mAcm 2 and charging-discharging cycling stability over 100 cycles）. As a proof-of-concept, the flexible, rechargeable all-solid-state Zn-air batteries were constructed, and displayed a maximum power density as high as 45.9 mW cm 2 among the top level of those reported previously.展开更多
