Open a family to keep every result attached to its sample, method and conditions.
Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
The conductive Co-MOF can be directly grown on Ni foam and used as an integrated supercapacitor electrode without conductive additives or polymer binders.
Caveat: The electrochemical device is a three-electrode test in KOH, not a full commercial cell.

Co-CTAB-6 improves cycling stability relative to Co-MOF, retaining 77.92% capacitance after 3000 cycles compared with 64.04% for Co-MOF.

CTAB changes the Co-MOF growth environment and Ni proportion; a CTAB:H6TATAT ratio of 6:1 gives the best storage performance among the tested series.
Caveat: CTAB-8 has a higher Ni/Co ratio but lower capacitance because the structure begins to collapse.

Ni2+ partially dissolves from Ni foam during solvothermal growth and is captured in cages or on the surface of the anionic Co-MOF through electrostatic interactions.
Caveat: Based on main-text XPS/EDS interpretation; detailed SI mapping for Co-CTAB-6 is missing.
main p.3 · Results and discussion · Fig. 2, Fig. 3, Table 1 · Linked to 3 structured results
The Co-MOF's relatively high conductivity is attributed to the unique anionic framework, balanced ions, redox-active [Co(H2O)6]2+ guest molecules and guest-framework charge-transfer interactions.
Caveat: Mechanistic interpretation is argued from structure and conductivity; the detailed conductivity Table S1 is missing with the SI.
