Researchers in order to develop the new mini super capacitor, they use 2 d carbon film, namely graphene, it's in the third dimension is the size of a single atom thick. The team also found a kind of easy method of making the batteries, namely USES the standard DVD burners. Al Kaldi said: "the traditional method of making miniature super capacitor involves labor-intensive lithography technology, it has been proved that this method is very difficult to build cost-effective device, so it greatly limits their commercial applications, and we use the light of consumer class carving burn, cost large area is much lower than traditional device used in production of graphene miniature super capacitor. After using this technology, we can use cheaper materials, in less than 30 minutes, on a single CD production more than 100 miniature super capacitor.
