Capacitive energy storage nanopore

Are nanoporous carbon electrodes suitable for electrochemical capacitive energy storage?

This review is dedicated to covering the recent progress in nanoporous carbon electrodes for electrochemical capacitive energy storage. It has started up with detailing the fundamental basics of EDL formation from the view point of ion–electrode correlations at planar, 2D electrodes.

Does capacitance increase in carbon nanopores?

(b) Differential capacitance per surface area versus pore width. Evidence of capacitance increase in carbon nanopores by using different approaches: (c) the packing ratio at different voltage.

What is the optimal KINV value for a nanopore?

The nanopore was initially fully charged at potential Uch = 3 V with respect to the bulk electrolyte. The inversion voltage is Uinv = −2.5 V and the optimal kinv value is kinv = 5.5 V/ns. The results are an average of 5 independent simulations. b Discharging time as a function of Uinv, calculated at optimal kinv values.

Can nanopatterning improve the energy density of electric double-layer capacitors?

Electrochem. 9, 81 (2018). Xing, L., Vatamanu, J., Smith, G. D. & Bedrov, D. Nanopatterning of electrode surfaces as a potential route to improve the energy density of electric double-layer capacitors: Insight from molecular simulations.

Why are graphene-like domains more efficient in nanopores?

Rather, their combination of simulations and data from nuclear magnetic resonance spectroscopy measurements indicates that the key factor is the extent of disorder, as smaller graphene-like domains can more efficiently store ions within the nanopores.

Can a non-linear voltage sweep charge a nanopore faster?

Guided by theoretical considerations, we also develop a non-linear voltage sweep and demonstrate, with molecular dynamics simulations, that it can charge a nanopore even faster than the corresponding optimized linear sweep.
