Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
The Co/Ni-HHTP@CP||AC asymmetric supercapacitor combines high energy density, high power density, and good cycling stability for energy-storage applications.
Caveat: Benchmarking against most MOF supercapacitors is asserted by the authors; this extraction records only first-hand values from this paper.

Although the paper discusses enhanced electron transport and lower resistance, it does not report a direct electronic conductivity value for the c-MOF powders or composites in the provided documents.
Caveat: EIS resistance is an electrochemical/device transport proxy, not a four-probe or two-probe electronic conductivity measurement.

Activated carbon paper provides oxygen-containing groups that coordinate metal ions, strengthen Co/Ni-HHTP@CP interfacial bonding, and improve thermal/electrochemical stability.
Caveat: The chemical-bonding interpretation is based on XPS shifts and morphology/TGA evidence, not a direct structural refinement of the CP interface.

The Co/Ni metal pair gives a stronger synergistic effect than Co/Cu or Cu/Ni, improving redox activity and charge storage.
Caveat: Exact capacitance values for Co/Cu-HHTP@CP and Cu/Ni-HHTP@CP at each current density are only shown graphically in the supplied main-page render and are not text-reported.

Charge storage in Co/Ni-HHTP@CP is dominated by diffusion-controlled Faradaic reactions rather than surface-capacitance dominance.
Caveat: Full comparison-electrode contribution values beyond the text-reported 10 mV s-1 point were read from percentage labels in rendered SI Figure S8.
