An all‐in‐one solvent! Hierarchical carbon–carbon nanotube composites were synthesized by using deep eutectic solvents (DESs) as reaction media, catalyst, and structure‐directing agent. The resulting carbon monoliths exhibited a combination of high conductivity, hierarchical structure, and mechanical properties that contributed to retention of 75 % of the initial capacitance at current densities of up to 29 A g −1 .
