Customer Feedback :
Q: How is a supercapacitor different from a capacitor?
A: Conventional capacitor is featured by high power density but low energy density, whereas, conventional battery is characterized by high energy density but low power density. Supercapacitors build a bridge between the two by combining high energy density and high power transmission states, that is, now you can charge your phone faster (high power density) and longer battery life (high energy density). So supercapacitors are considered the future of renewable energy.
How are graphene supercapacitors better than ordinary supercapacitors?
Conventional supercapacitors use activated carbon; the specific surface area is usually about 1,500 m2/g. Most of the charge is stored on the wet surface of activated carbon.
The surface area of graphene has a higher conductivity, which is conducive to allowing charges to move faster than activated carbon. Graphene is usually in the form of irregular small flakes. This provides 3D storage capacity instead of the 2D of activated carbon. In addition, the edges of graphene attract charges.
