Super capacitors have been recognized as promising energy storage devices due to their fast charge-discharge time, very high power density and long life cycle period. It is commercially available but widespread usage is restricted by their high cost and low energy density. These drawbacks can be mitigated by developing a new class of high performance carbon electrodes which consist of a combination of materials produced from abundant, cheap and environmentally friendly resources with low processing costs. ARCI has developed graphene-like activated porous carbon by a low-cost chemical activation process using petroleum coke (petcoke), which is a great value addition for the waste disposed in large quantities in oil industry. The resulting carbon material delivers excellent super capacitor performance in terms of capacitance, rate capability and cyclic stability in comparison to
