energy storage devices
Conventional (dielectric) capacitors
Conventional batteries
Electrolytic capacitor
Fuel cells
Electric double-layer capacitors (EDLCs)
VGA Nuremberg uses hybrid diesel-electric battery engine
with EDLCs since 2001
Mannheim Stadtbahn operates light-rail vehicle with EDLCs
for breaking energy since 2003
Model and theory
Carbon vs metallic pores
Opening/closing of a pore, and inter-pore interactions
Single two-dimensional layer of ionic liquid inside a slit-like
pore
Mean-eld like approximation: no
uctuations/correlations
Short-range repulsive (hard-sphere type) interaction are not
properly accounted for
