In article number 2002053, Keun Hyung Lee, Won Cheol Yoo, and co‐workers present a facile strategy to effectively utilize the surface of carbonaceous electrodes using 3D ordered/interconnected large mesoporous carbons and solidified ionic liquid electrolytes, known as ionogels. The fabricated all‐solid‐state supercapacitors exhibit record‐high energy and power densities that exceed the upper bound of the Ragone plots.
