The design and fabrication of graphene‐based micro‐supercapacitors are reported on page 4501 by Majid Beidaghi and Chunlei Wang. Addition of carbon nanotubes (CNTs) between the graphene sheets and the arrangement of electrodes in a side‐by‐side structure increases the accessibility of electrode materials. A two‐step fabrication of electrodes based on electrostatic spray deposition (ESD) and photolithography lift‐off is explained. The fabricated devices show exceptional high rate capability and frequency response. Image courtesy of Kristy Jost.
