4 FAQs about [Supercapacitor graphene battery South Korea]

Are graphene supercapacitors based on a lithium-ion battery?

Now Santhakumar Kannappan at the Gwangju Institute of Science and Technology in Korea and a few pals say they have a solution based on the wonder material of the moment–graphene. These guys have built high-performance supercapacitors out of graphene that store almost as much energy as a lithium-ion battery.

Could graphene replace Li-ion batteries?

While the South Korean research has rekindled notions that graphene could be the solution to increasing the storage capacity of supercapacitors to the point where they could offer an alternative to Li-ion batteries,the general research trend has moved away from this aim.

How much energy can a supercapacitor store?

Kannappan and co have measured the performance of their supercapacitor and are clearly impressed with the results. They say it has a specific capacitance of over 150 farads per gram can store energy at a density of more than 64 watt-hours per kilogram at a current density of 5 amps per gram.

What are supercapacitors & how do they work?

To fill in a little bit of the background, supercapacitors are a kind ofcross between a battery and a capacitor. While batteries depend on a liquid electrolyte that changes the chemical states of ions in order to operate, a capacitor stores the ions on the surface of its electrodes in the form of static electricity.
