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

Graphene Could Become World's Best Super Battery

You know graphene, the super material that's strong enough to withstand diamond cutters » 9/18/08 1:30am 9/18/08 1:30am? Turns out that not only may it replace silicon as the de rigeur component of microchips, it's on track to becoming the next megabattery as well. Engineers at the University of Texas in Austin have found a way to store electrical…
