A team of researchers from UCLA Berkeley has developed a new supercapacitor which is paper-thin, super-fast to charge and can match batteries with its energy storage density.
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…
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.
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.
