Ultra‐high volumetric performance electrochemical double layer capacitors based on high density aligned nano‐porous microwave exfoliated graphite oxide have been studied. Elimination of macro‐, meso‐, and larger micro‐pores from electrodes and controlling the nano‐morphology results in very high volumetric capacitance, energy, and power density values.
