Abstract

Cobalt oxide nanosheets (Co₃O₄ NSs) are grown on carbon paper (CP) by an efficient and facile electrodeposition method. When directly used as free-standing cathode for lithium–oxygen batteries, the Co₃O₄ NSs/CP is found to be robust and shows enhanced specific capacity and cycling stability.
