Graphene supercapacitor holds promise for portable electronics

Researchers have used a standard LightScribe DVD optical drive to produce electrodes composed of an expanded network of graphene that shows excellent mechanical and electrical properties as well as exceptionally high surface area. These LSG supercapacitors demonstrate high-performance graphene-based electrochemical capacitors that maintain excellent electrochemical attributes under high mechanical stress and may be ideal energy storage systems for next generation flexible, portable electronics.
