Best of Both Worlds capability Storage from Graphene Supercapacitors

February 22, 2013 · Print This Article

If UCLA researchers are exact, a new supercharger could convert both the way we capability our electronics and recycle their old sources of energy. Bringing together the quick-charging qualities of a capacitor and the energy-holding capacities of a battery, graphene supercapacitors could replace the often toxic batteries we currently use to potential our electronics.

Batteries and capacitors are relatively similar devices, functionally speaking. Standard batteries consist of two chemicals that react with

each other, separated by a barrier, and have a circuit amidst them; capacitors are composed of two oppositely charged metal plates, separated by an insulator, with a circuit amoung them. When electrons flow through the circuits of batteries and capacitors alike they supply electricity. Although capacitors can be charged very quickly, they don’t hold nearly as much energy as batteries.

Graphene supercapacitors would solve the energy holding problem of capacitors. <a href=”http://portal.acs.org/portal/acs/corg/content?_nfpb=true&_pageLabel=PP_MULTICOLUMN_T2_66&node_id=893&use_sec=false&sec_url_var=region1&__uuid=0c8c9be8-5815-4bac-aaf9-a3e3bf0e0664″ […]
