Supercapacitors for electric vehicles: what construction?

Attendance was 40% up at the recent IDTechEx event in Santa Clara California with its 200+ exhibitors and nine parallel conferences. The Supercapacitors conference and associated Masterclass had a larger attendance and sturdy debate. There was a Graphene Live conference that also covered some of this topic. Views are changing. In two IDTechEx interviews of graphene companies both said that graphene is not the best option in increasing energy density. They believed that none of the so-called exohedral options - single atomic layer carbon allotropes in the main - would prevail. Further development of hierarchical structures with graded pores were the way to go. Many said aqueous electrolytes are promising. Supercapacitors intermediate between purely electrostatic, symmetric Electrochemical Double Layer Capacitors EDLC and lithium-ion batteries have either pseudocapacitance u...
