Stanford team develops new ultrahigh surface area 3D porous graphitic carbon material for improved energy storage

Green Car Congress

Stanford University scientists have created a new ultrahigh surface area three-dimensional porous graphitic carbon material that significantly boosts the performance of energy-storage technologies. The process begins with conducting hydrogel, a water-based polymer with a spongy texture similar to soft contact lenses.
