Abstract

A carbon and binder-free cathode for use in Li–O₂ cells which is based on free-standing CuCo₂O₄ nanowires supported on a nickel foam was synthesized by an efficient hydrothermal method. The resulting hierarchical porous and umbrella structures of the hybrid CuCo₂O₄@Ni foam cathodes present an excellent rate capability and cycle performance.
