Super energy storage: Activated graphene makes superior supercapacitors for energy storage. Scientists at the U.S.
Department of Energy's Brookhaven National Laboratory have helped to uncover the nanoscale structure of a novel form of carbon, contributing to an explanation of why this new material acts like a super-absorbent sponge when it comes to soaking up electric charge. The material, which was recently created at The University of Texas -- Austin, can be incorporated into "supercapacitor" energy-storage devices with remarkably high storage capacity while retaining other attractive attributes such as superfast energy release, quick recharge time, and a lifetime of at least 10,000 charge/discharge cycles. Supercapacitors are similar to batteries in that both store electric charge. Batteries do so through chemical reactions between metallic electrodes and a liquid electrolyte.
Because these chemicals take time to react, energy is stored and released relatively slowly. Nanotechnology. Just give me the FAQ The next few paragraphs provide a brief introduction to the core concepts of nanotechnology, followed by links to further reading.
