New Carbon for Electrical Energy Storage

Researchers in the Materials Science and Mechanical Engineering department at the University of Texas at Austin have developed a new, highly-conductive carbon material with the potential to increase energy storage capacity in supercapacitors. Potential applications include electric vehicles, remote devices, and replacing lead acid batteries.

    00:00:05 We're at The University of Texas in the Department of Materials Science and Engineering. I'm Meryl Stoller. Hi, I'm Yanwu Zhu. I'm a post-doc fellow in Professor Ruoff's Group. We're standing here with a model of a new carbon material that we synthesized here. It is based upon graphene, but unlike graphene, graphene has 6-sides of carbon atoms, this material has 5, 6, 7 and 8 sides. What that does is enable a very curved surface. This very curved surface, which forms these micropores, along with its very, very high [surface] area, enables it to be very useful for such applications as supercapacitors. Supercapacitors are a form of electrical energy storage similar to rechargeable batteries.

    00:00:55 What this material may do is enable very high-power and very high-energy supercapacitors which will enable them to potentially be used in electric cars, remote devices, as well as potentially replacing lead-acid batteries. This material, not only is it very novel and new, it's manufactured with a process that is very easily scalable, as well as potentially very, very inexpensive.
