Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
Co4-Ir MOF anodes show practical compatibility in soft-packed NCM523 full batteries and activated-carbon hybrid lithium-ion capacitors.
Caveat: Application cells include conductive carbon/binder composites and non-MOF cathodes; values should not be treated as pristine MOF transport values.

Capacity decay is attributed to unstable SEI and electrolyte consumption in high-surface-area nanostructured MOFs; further tuning of size, microstructure, composition and electrolyte additives is suggested.
Caveat: The explanation is proposed by the authors rather than proven by direct SEI quantification.
5 · Results and Discussion · Linked to 2 structured results
Ir(ppy-COOH)3 metallolinkers bridge Co4(mu4-O) units into pi-pi stacked layers, and the highly connected Ir atoms help form robust bimetallic frameworks, producing enhanced bulk conductivity.
Caveat: Conductivity was measured on a pressed powder pellet; solvent/activation state before pressing is not fully isolated.
3 · Results and Discussion · Figure S5 · Linked to 3 structured results
The laminated stacking structure and ordered microporous framework promote Li-ion transport and high-rate storage.
Caveat: The Li-ion diffusion coefficient is extracted from GITT rather than directly from a structural transport measurement.
9 · Conclusion · Linked to 5 structured results
Co4-Ir MOF stores Li+ mainly by an organic moiety-dominated mechanism involving carboxyl groups, benzene rings, pore channels and interlamination space, with no Co(0) conversion detected after discharge.
Caveat: Mechanism is inferred from ex situ spectroscopy/diffraction and electrochemical signatures.
