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.
