Graphene is a promising electrode material for for the prevention of graphene supercapacitor electrodes from sponge-like graphene.

Supercapacitors are similar to batteries in that both store electric charge batteries do so through chemical reactions between metallic electrodes and a liquid electrolyte because these chemicals take time to react, energy is stored and released relatively slowly but batteries can store a lot of energy and release it over a fairly long time. Reversibly compressible, highly elastic, and durable graphene tolerant supercapacitor electrode free sponge based on reduced graphene oxide. Besides, an asymmetric supercapacitor is made with the co 3 o 4 [63%]@srgo[37%] hybrid and activated carbon as a positive and a negative electrode, respectively electrochemical results indicate an energy density of 233 w h kg −1 at a high power density of 2300 w kg −1 (discharge time of about 42 s) and 62% retention even at a.

Like batteries, however, supercapacitors use a flammable electrolyte solution, and so are vulnerable to leakage and fires not only is the group's supercapacitor solvent-free – which means it does not contain a flammable liquid – but its compact design makes it more durable, and its energy storage capacity and charge-discharge lifespan are better.
