Graphene Could Double Ultracapacitor Density

摘要

Researchers at the University of Texas at Austin are experimenting with using the nanomaterial graphene to improve-and ultimately double-ultra-capacitor, a novel chemically modified graphene (CMG). Ultracapacitors hold many advantages-higher power ca- pability, longer life, wider thermal operating range, light-er-over batteries, but storage density needs to be im-proved for ultracapacitors to be competitive.
