Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
The Ni-tdc-bpe(0.5)//AC hybrid supercapacitor delivers high energy density and stable cycling relative to the pristine-control devices.
Caveat: Device data are application context; conductive-MOF evidence is strongest for pristine pellet conductivity and powder/electrode controls.

The four primary Ni-MOF powders are phase-pure and highly crystalline by PXRD comparison with simulated patterns.
Caveat: No CIF files were provided in this extraction bundle; assignment relies on reported simulated-pattern comparison.

Replacing bpy with the more delocalised bpe coligand increases electrical conductivity by over six orders of magnitude and improves capacitance.
Caveat: Conductivity values are pellet four-probe measurements; DFT band gaps were extracted from figure annotations rather than text.

The Ni-MOF electrode redox processes are predominantly diffusion-controlled at lower scan rates, consistent with b values near 0.5 and low capacitive fractions at 20 mV/s.
Caveat: Capacitive fractions increase at 100 mV/s, especially for Ni-tdc-bpe.
430 · Results and Discussion · Figures S7-S12 · Linked to 6 structured results
Ultrathinning/size optimisation shortens charge-transfer pathways and improves charge-discharge efficiency, with Ni-tdc-bpe(0.5) showing the strongest EIS and capacitance performance.
Caveat: EIS support is qualitative because fitted Rct/Rw numbers were not reported.
