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

This Graphene-Coated Silicon Power Cell Signals a Battery-Free Future

Imagine a future without batteries. But in the same future, your cell phone charges in minutes and stays charged for weeks. Thanks to the world's first silicon power cell, this future might not be so far away—and graphene is helping us get there. » 10/25/13 3:21pm 10/25/13 3:21pm

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…
