Old Cigarette Butts Could Be Used To Make Supercapacitors

The world has too many nasty old cigarette butts. On the other hand, the world could use some supercapacitors, the high-tech replacements for batteries that could potentially charge in seconds. Scientists in South Korea have found a simple process to turn used cigarette filters into high-performing material that works… » 8/05/14 3:18pm 8/05/14 3:18pm

Carbon Nanotube Supercapacitors May Replace Clunky Car Batteries

Carbon nanotubes are one of the surprising new carbon » 9/22/08 9:00am 9/22/08 9:00am , and it looks like their application in supercapacitors may have a role in replacing clunky old car battery tech. Scientists at the University of Texas at Dallas have invented a technique to make supercapacitor "paper" made from randomly tangled carbon nanotubes…
