Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
Optimising the channel length of 2D conductive MOF electrodes is electrolyte-dependent: thick films benefit high-mobility KCl by increasing substrate-normalised capacitance, while short channels are important for less-mobile ionic liquids.
Caveat: The study uses three-electrode films and two electrolytes; device-level symmetric-cell performance was not reported.

For these oriented Cu3(HHTP)2 SURMOF electrodes, the pore channel length corresponds to the film thickness because one-dimensional pores are perpendicular to the substrate surface.
Caveat: The authors note this correspondence is in the absence of defects; intermediate cycle thicknesses are inferred from synthesis cycle number rather than directly reported.

Scan-rate-dependent capacitance scales with synthesis cycles, indicating that the Cu3(HHTP)2 pore space is essentially accessible to the electrolyte ions and that pore-blocking defects have a minor impact.
Caveat: For IL at fast scan rates, the outer capacitance is much smaller than the total capacitance, indicating kinetic inaccessibility on short timescales even if pores are not blocked.
269 · Results and Discussion · Figures 2c,f, S5, S10 · Linked to 3 structured results
In pure [BMIM][TFSI] ionic liquid, ion transport in Cu3(HHTP)2 electrodes is predominantly diffusion-controlled, and longer channel length decreases capacitance performance.
Caveat: Some b-values increase with thickness, indicating increasing surface-process contribution even in IL.
271 · Results and Discussion · Figure 5; Figure S18 · Linked to 6 structured results
In highly mobile aqueous KCl electrolyte, Cu3(HHTP)2 EDLC kinetics are mainly surface-controlled and diffusion resistance only weakly limits performance, even for thicker films.
Caveat: The Dunn method still shows diffusion-controlled contributions, especially at low scan rate.
