The super capacitor is mainly stored on the surface of the conductor to store charge, so the larger the area used to store the charge, the more dense the separation of the charge, the greater the capacitance. At present, most of the super capacitor porous activated carbon structure to expand the storage area, the large surface area of charge coupled with very small separation distance, which compared with the ordinary capacitor energy storage capacity is larger, compared with the battery energy transfer faster. But in some devices, the charge time of a few seconds still seems a little long.

By the American JME company president John. A research team led by Miller, the structure and the electrode on the super capacitor is a new designed, so that the charging time to 200 microseconds (per human blink time is about 0.2 seconds ~0.4 seconds, which is 200 thousand microseconds ~40 million microseconds). The new electrode was designed by Outlaw Ron of College of William and Mary in the United States, Virginia. The whole structure is composed of a set of graphene sheets which are perpendicular to the base. The graphene substrate is only one atom thick, and is formed by plasma chemical deposition. The base is made of 10 nm thick graphite. Experiments show that compared with the original porous activated carbon structure of the super capacitor, the new high efficiency, can be completed in a shorter period of time.
