How about a set-up that charges in 16 seconds and can be recharged over 10,000 times? In home electronics, capacitors charge rapidly, but also discharge in seconds. Supercapacitors made of graphene retain the former trait, but release the charge gradually, like a battery. However, a downside is that energy density is on par with existing lithium-ion tech. "
The writer may be "factually correct ",as it stands currently,however,I'm of the view Graphene Supercapacitors,which use Ion beam Technology have a superior energy density to both Graphene Supercapacitors which use Laser technology and Lithium-ion tech.
