Devil’s Postpile of Graphene and Nanotubes December 4, 2012

nanotubes growing from graphene

That, dear reader, is a cluster of carbon nanotubes attached to a graphene sheet. A candidate for the best supercapacitor substrate ever created, it’s the product of a Rice University lab that wasn’t even trying to make supercapacitor substrates. Electrical testing showed no resistance to the flow of current at the junction, and they weren’t even trying.

"The performance we see in this study is as good as the best carbon-based supercapacitors that have ever been made," Tour said. "We’re not really a supercapacitor lab, and still we were able to match the performance because of the quality of the electrode. It’s really remarkable, and it all harkens back to that unique interface."
