Scientists from the Korea Advanced Institute of Science and Technology (KAIST) say they have developed a new supercapacitor based on nitrogen and graphene. The new device has double the energy storage capacity of conventional capacitors. They say that the key technology here is doping the graphene with Nitrogen.
The team tested the capacitor and said that it showed no change in its capabilities even after 230,000 charge/discharge cycles.
