Article Title

Hierarchical Co3O4 porous nanowires as an efficient bifunctional cathode catalyst for long life Li-O2 batteries

Keywords

lithium–oxygen batteries, bifunctional cathode catalyst, Co3O4 nanowires, cycling stability

Abstract

Hierarchical Co3O4 porous nanowires (NWs) have been synthesized using a hydrothermal method followed by calcination. When employed as a cathode catalyst in non-aqueous Li–oxygen batteries, the Co3O4 NWs effectively improve both the round-trip efficiency and cycling stability, which can be attributed to the high catalytic activities of Co3O4 NWs for the oxygen reduction reaction and the oxygen evolution reaction during discharge and charge processes, respectively
