Operando interlayer expansion of curved graphene for dense supercapacitors

translation: energy densities comparable to batteries (~50, ~100 Wh/l) and power output characteristic of supercapacitors (~70 kW/l at ~10 Wh/l). sounds useful, fingers crossed they can figure out how to scale this up.

Any exotic materials required? Just carbon?
