Accelerating charging dynamics in sub-nanometer pores [PDF]

open access: yes, 2013
Having smaller energy density than batteries, supercapacitors have exceptional power density and cyclability. Their energy density can be increased using ionic liquids and electrodes with sub-nanometer pores, but this tends to reduce their power density ...

Controlling internal barrier in low loss BaTiO3 supercapacitors [PDF]

open access: yes, 2009
Supercapacitor behavior has been reported in a number of oxides including reduced BaTiO3 ferroelectric ceramics. These so-called giant properties are however not easily controlled. We show here that the continuous coating of individual BaTiO3 grains by a

Ion-liquid based super-capacitors with inner gate diode-like separators

open access: yes, 2019
We demonstrate that the capacitance of ionic-liquid filled supercapacitors is substantially increased by placing a diode-like structure on the separator membrane. We call the structured separator: gate, and demonstrate that the order of a p-n layout with
