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 KNiCoPO4//AC asymmetric cell reaches 22 Wh kg^-1 at 363 W kg^-1 and retains 99% capacitance after 5000 cycles at 5 A g^-1.
Caveat: Device-level performance depends on activated carbon counter-electrode and full-cell construction.
p011 · 3.4 · Fig. 7e-f · Linked to 3 structured results
The paper discusses poor MOF electrical conductivity and uses EIS/contact resistance language, but it does not report direct electrical conductivity, mobility, Seebeck coefficient, or thermal conductivity values.
Caveat: Transport evidence should be treated as application-level interfacial resistance rather than intrinsic conductive-MOF transport.

The office SI text layer is incomplete, but the rendered SI surrogate provides the SI table bodies used for lattice, XPS, EIS, and comparison-table verification.
Caveat: The rendered SI is a local surrogate for the same SI content and was not fetched externally.

A small cobalt fraction in NiCo-M, especially nominal Ni/Co = 10:1, optimises the MOF electrode performance by increasing active Ni3+/Co2+ species, unpaired electrons, pore width, and charge-transfer kinetics.
Caveat: This is an electrochemical electrode comparison, not a direct intrinsic conductivity measurement.

Converting NiCo-M (10:1) into KNiCoPO4 improves specific capacity from 437 to 522 C g^-1 at 0.5 A g^-1.
Caveat: Comparison is between electrode materials measured under similar three-electrode conditions but both include conductive additive/binder/substrate in electrode form.

Hydrothermal phosphate treatment replaces BTC in NiCo-M (10:1), producing KNiCoPO4 while preserving a Ni/Co ratio close to the precursor.
Caveat: The exact atomistic substitution pathway is inferred from phase/spectroscopy evidence, not followed in situ.
p008 · 3.3 · Fig. 5 · Linked to 3 structured results
KNiCoPO4 has lower fitted Rs and RCT than NiCo-M (10:1), which the authors attribute to phosphate-assisted ion accessibility and improved interfacial charge transfer.
Caveat: EIS-derived values are electrode/electrolyte interface parameters, not standalone bulk conductivity.
