A novel 3D free-standing cathode without carbon or binder was prepared and applied for Li-O2 battery,which consisted of spinel CuCo2O4 nanowires on Ni foam synthesized through a hydrothermal method.The umbrella skeleton nanostructure formed by the interconnected CuCo2O4 nanowires provides a large specific surface area and more active sites.
