New graphene framework bridges gap between traditional capacitors, batteries

Researchers at the California NanoSystems Institute (CNSI) at UCLA have set the stage for a watershed in mobile energy storage by using a special graphene material to significantly boost the energy density of electrochemical capacitors, putting them on a par with lead acid batteries.

The material, called a holey graphene framework, has a three-dimensional, perforated structure characterized by tiny holes; it not only increases energy density (the amount of energy stored and ready for use) but allows electrochemical capacitors to maintain their high power density (the amount of power per unit of mass or volume), according to Xiangfeng Duan, a UCLA professor of chemistry and biochemistry who led the research...
