Make Your Own Supercapacitor with an Ordinary DVD

Make Your Own Supercapacitor with an Ordinary DVD

You are thisclose to the breakthrough energy storage technology of the next millennium if you a) have a computer, b) buy a blank DVD, c) own or have access to a DVD label-burning device and d) pre-treat your DVD with a thin film of graphite oxide. Well, there might be an extra step or two involved, but that’s the basic idea behind a new method for making high-efficiency energy storage devices called supercapacitors. Researchers at UCLA headed by graduate student Maher F. El-Kadyh have demonstrated that an ordinary DVD pre-treated with graphite oxide can be inscribed by laser into components for a graphene-based supercapacitor using a commercially available CD/DVD label burning drive, in this case from the company
