Supercapacitor Materials Improvement: Gateway to Multi $ Billion Busin
Supercapacitor materials are rapidly improving by new routes. The active materials are the dominant part of cost and the cause of limitations such as flammability, toxicity, cost, energy density and self- discharge. Currently the active electrodes almost always consist of bulk "hierarchical" carbon with a range of pore sizes, often made the old way from botanical materials.
