Abstract

A reduced free-standing Co₃O₄@Ni cathode for Li–O₂ batteries constructed from porous Co₃O₄ nanosheets is synthesized through a simple two-step method. The particle reduction of Co³⁺ to Co²⁺ improves the electrochemical activity of the electrode with enlarged discharge capacity and lower charge potential.
