Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
The Co1/2Fe1/2-MOF composition is the best-performing anode in the series, delivering about 1132 mAh g-1 after 200 cycles at 0.1 A g-1 and 660 mAh g-1 after 500 cycles at 2 A g-1.
Caveat: Battery electrodes contain conductive carbon and binder, so values are not pristine-framework-only electrical transport metrics.
p001 / article p.10097 · Abstract · Fig. 5 · Linked to 3 structured results
The paper discusses enhanced conductivity and rapid charge transfer but does not report a direct electronic conductivity or thermoelectric measurement.
Caveat: Conductivity is inferred from EIS and electrochemical performance.
p002 / article p.10098 · Introduction · Linked to 2 structured results
Although the article describes a solvothermal approach, the explicit Co1/2Fe1/2-MOF recipe reports room-temperature solution mixing, TEA addition, and 8 h ultrasonication without a stated solvothermal temperature.
Caveat: Route type retained as solvothermal to reflect author terminology, but recipe completeness is partial.
p002 / article p.10098 · Materials synthesis and characterization
ICP data confirm that the mixed-metal products contain both Co and Fe, with Co1/2Fe1/2-MOF measured at Co:Fe = 0.51:0.49.
Caveat: ICP confirms elemental composition but not crystallographic placement of both metals in the same framework.

After cycling, Co1/2Fe1/2-MOF loses long-range order but maintains particle integrity without pulverisation or fractures.
Caveat: Post-cycling SI figures S4 and S5 were not visually available in the supplied SI; main Fig. 9 and text support the claim.

Adding bimetal ions approximately increases the specific surface area relative to Co-MOF and Fe-MOF, providing more active sites.
Caveat: Absolute BET areas are modest for MOFs; no pore-size distribution values were extractable from the supplied documents.

Bimetallic Co/Fe coordination enhances electronic coupling and charge-transfer kinetics, lowering Rct relative to Co-MOF and Fe-MOF controls.
Caveat: No four-probe electronic conductivity measurement is reported; transport improvement is inferred from EIS, XPS shifts, and electrochemical kinetics.

Co1/2Fe1/2-MOF exhibits higher pseudocapacitive contribution than Co-MOF and Fe-MOF, supporting faster Li-ion transport during cycling.
Caveat: The strongest contribution values are from CV kinetic analysis rather than direct diffusion-coefficient measurements.
