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

These New Graphene Supercapacitors Could Finally Power An Electric Car

A team of South Korean scientists has developed a new graphene supercapacitor that can store almost as much energy as a lithium-ion battery, but charge in only 16 seconds. This makes it an ideal material to store braking energy and could be exactly what the electric car industry needs. » 11/12/13 6:00pm 11/12/13 6:00pm

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…
