The p-CuO/G hybrid was prepared via the hybridization of a porous 1D/2D CuO mixture with 2D graphene. As an oxygen-electrode electrocatalyst for LieO(2) cells, the p-CuO/G hybrid exhibited high reversibility with a low voltage gap compared with a graphene electrode during 120 dischargeecharge cycles under a fixed capacity regime of 1000 mA h g(-1). We demonstrated the oxygen reduction and evolution kinetics of the p-CuO/G hybrid using electrochemical impedance spectroscopy. (C) 2016 Elsevier B.V. All rights reserved.
