N2 - Atomic-thick interfacial dominated bifunctional catalyst NiO/CoO transition interfacial nanowires (TINWs) with abundant defect sites display high electroactivity and durability in the oxygen evolution reaction (OER) and the oxygen reduction reaction (ORR). Density functional theory (DFT) calculations show that the excellent OER/ORR performance arises from the electron-rich interfacial region coupled with defect sites, thus enabling a fast-redox rate with lower activation barrier for fast electron transfer. When assembled as an air-electrode, NiO/CoO TINWs delivered the high specific capacity of 842.58 mAh gZn−1, the large energy density of 996.44 Wh kgZn−1 with long-time stability of more than 33 h (25 °C), and superior performance at low (−10 °C) and high temperature (80 °C). © 2019 Wiley-VCH Verlag GmbH & Co.
