Summary: Brown University engineers have created a new battery that uses plastic, not metal, to conduct electrical current. The hybrid device marries the power of a capacitor with the storage capacity of a battery. A description of the prototype is published in Advanced Materials.
"Batteries have limits," said Tayhas Palmore, an associate professor in Brown’s Division of Engineering. "They have to be recharged. They can be expensive. Most of all, they don’t deliver a lot of power. Another option is capacitors. These components, found in electronic devices, can deliver that big blast of power. But they don’t have much storage capacity. So what if you combined elements of both a battery and a capacitor?"
