3D hierarchical Co 3 O 4 twin‐spheres and their electrochemical properties are reported by Feng Li, Dianzhen Jia, and co‐workers on page 4052 . A multistep splitting growth originating from 1D nanorods is proposed to understand the formation of the 3D nanoarchitectures. Supercapacitors fabricated with the 3D materials exhibit excellent performance in energy storage.
