Researchers create graphene ultracapacitors

admin    News    

Researchers are working on nanotech based energy storage systems or ultracapacitors using graphene. How does it work? One atom thick sheets of carbon are densly packed together. When a charge is applied, electrons go into the sheets and get stuck to electrons of opposite charges. The high amount of surface area allows a high-density storage of electrons. To further increase the amount of electrical charge that can be used the sheets are polarized with oxygen, hydrogen and nitrogen. Don’t expect to drop one of these into your new electric rig or prius anytime soon, these are still far from going to market. Read More
