Better Supercapacitors from Laser-scribed Graphene

In Batteries, technology on April 2, 2012 at 6:19 pm

Efficient energy storage is as much a problem as energy generation, and supercapacitors are a promising alternative to batteries for this. Capacitors can charge and discharge faster than batteries, but they’ve lacked the ability to store as much power. Supercapacitors made from graphene and a gelled electrolyte are challenging battery’s characteristics.
