Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
LiTFSI in EC:EMC is preferred over LiPF6 for Cu3(HHTP)2 electrodes because XRD shows markedly better framework preservation after cycling.
Caveat: Mechanistic attribution to HF formation from water residues is plausible but not directly quantified here.

Flake-like Cu3(HHTP)2 has more accessible pore channels and shorter Li+ diffusion pathways than rod-like Cu3(HHTP)2, reducing diffusion limitation in Faradaic lithium storage.
Caveat: Pore orientation is inferred from prior TEM literature and the authors' morphology model rather than directly measured here for every particle.
p012 to p013 · Conclusion · Figure 7 · Linked to 8 structured results
Activation at 60 C was chosen as a compromise between guest removal and retention of Cu3(HHTP)2 crystallinity.
Caveat: The tabulated guest-content series is for flake-like Cu3(HHTP)2; the crystallinity trend is discussed for both morphologies by PXRD.

Uncoated two-probe pellet conductivities were probably limited by poor electrode contacts; gold contact coating greatly increased the measured through-plane conductivity.
Caveat: The highest value was demonstrated for gold-coated flake-like pellets, not both morphologies.

Lithium storage in Cu3(HHTP)2 is Faradaic and involves reversible Cu2+/Cu+ redox, with additional possible linker redox activity indicated by FTIR and sXAS.
Caveat: The exact potential-resolved mechanism remains unresolved; Cu2+ is still observed at the most lithiated state and linker redox is partly reversible.
p007 to p013 · Results and Discussion; Conclusion · Figure 2 · Linked to 3 structured results
The in situ XRD 001 shift suggests structural widening during lithiation, more plausibly from Li+ accommodation in MOF pores than direct intercalation between sheets.
Caveat: The precise lithiated crystal structure and possible solvent co-intercalation remain unclear.
