Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
Despite limited surface area, Cu-BHT outperforms many higher-surface-area MOFs because conductivity, stability and redox activity dominate the battery performance.
Caveat: Outperformance comparison relies on literature comparison table and not all external materials are extracted as first-hand rows.

CNT conductive additive is necessary for electrode preparation because CNT-free Cu-BHT/PVDF electrodes show very low capacity while 5 wt% CNT electrodes retain useful capacity.
Caveat: This is an electrode formulation claim, not a contradiction of the intrinsic 231 S cm-1 framework conductivity.
p007 / SI page 7 · Figure S10 discussion · Figure S10; Figure S11 · Linked to 2 structured results
The intrinsically high electronic conductivity of the Cu-BHT framework is proposed to enable fast redox activity, high rate capability and high energy density.
Caveat: Battery electrodes include CNT conductive additive, so application rate data are not solely pristine-framework transport measurements.
p004 / 12019 · Electrochemical Performance · Figure 2 · Linked to 4 structured results
The strong two-dimensional chelating and d-pi conjugated framework gives Cu-BHT broad chemical stability and retained crystallinity under battery-relevant environments.
Caveat: Chemical stability is assessed by PXRD retention after 25 h exposures, not by long-term chemical ageing beyond cycling.
p004 / 12019 · Materials Characterization and Stability Evaluation · Figure 1b; Figure S4 · Linked to 3 structured results
DFT and electrochemistry support reversible storage of up to four Li ions per Cu-BHT cell within 1.5-3.0 V vs Li+/Li.
Caveat: DFT capacity is an ideal prediction; text notes interlayer effects are assumed negligible.

Lithium storage redox is assigned mainly to BHT ligand sulfur sites rather than Cu metal centres; Cu(II) hubs maintain framework integrity and conductivity.
Caveat: Mechanistic assignment combines ex situ XPS and DFT rather than direct operando structural observation.
