Abstract

An advanced electrode for high-performance electrochemical capacitors has been designed by growing ultrathin mesoporous Co₃O₄ nanosheet arrays on the Ni foam support. This unique 3D electrode manifests exceptional supercapacitive performance with ultrahigh specific capacitance at high current densities and excellent cycling stability.
