A group of scientists from Brown University suggested a way to create more efficient electrodes for electrochemical batteries than those that are currently used in the manufacture of batteries.
It is known that graphene - a monatomic layer of carbon flat. Enlarge conductivity "sheet" of graphene prompted by increasing graphene area per unit electrode surface. To do this, the developers have found a way without damaging the "crumple" and "crush" the graphene sheet. Technologically, all relatively simple. Graphene is applied to the heat-shrinkable plastic. This plastic has long been used in children's sets for creativity such as Shrinky Dink. Crafts placed in the oven and reduced in size to 1/4 without losing the proportions. After warming up on a graphene substrate shrinks and forms folds.
Scientists have even created a catalog of reliefs graphene depending on the shrinkage mode (pictured above). Related Products :
