Figure 4.

The dimensionless charging timescale ${\tau }_2^{*}$ for the electrodes with $1.3\le H^{*}\le 1.7$ at the high external potentials $10\le U^{*}\le 20$ versus the scaling law (13). The inset shows the same timescale versus the scaling law (11); the pores with $H^{*}\le 1.7$ and $H^{*}\ge 2.0$ are marked with purple and orange ellipses.
