Operando interlayer expansion of curved graphene for dense supercapacitors nature.com 32 points by westurner 7 days ago
baq a day ago 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?
