A novel graphene-based electrode, produced with a standard LightScribe DVD optical drive, ends the search for an optimal electrochemical capacitor. The discovery could pave the way for a new class of flexible energy-storage devices. Electrochemical capacitors, also called ultracapacitors or supercapacitors, store higher amounts of charge than regular capacitors and have garnered attention as energy-storage devices because they charge and discharge faster than batteries. However, unlike batteries, they are limited by low energy densities. Researchers have sought an electrochemical...Read full article
