Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
IL0.5@MOF acts as a dendrite crossover barrier in symmetric sodium cells for more than 100 h without short-circuit signs.
Caveat: Demonstrated at 0.1 mA cm-2 and room temperature in the reported symmetric-cell configuration.

IL0.5@MOF is electrochemically stable up to 7 V vs Na+/Na and retains its diffraction pattern after LSV, supporting compatibility with high-potential sodium cathodes.
Caveat: LSV was tested in Na/IL0.5@MOF/SS cells; full cathode-cell cycling is not reported.

Na[EMIm][TFSI] is introduced into the Zn-MOF-74 channels/porous structure, as supported by IR, XRD and a large BET surface-area drop.
Caveat: Adsorption fitting values are reported for Zn-MOF-74 and IL0.5@MOF in SI Table S3; loading-series cell parameters from SI Figure S2 are visual estimates.

The IL0.5@MOF composition gives the best balance of pore occupation and ion mobility, producing the highest reported conductivity and lowest activation energy in the series.
Caveat: Mechanistic interpretation is inferred from composition trends, conductivity, activation-energy labels and SI EIS spectra, rather than a direct Na+ trajectory measurement.
p008 / journal page 8 · 3.2 Electrochemical Characterization · Figure 5 · Linked to 3 structured results
Both ion-hopping and vehicle-type sodium transport can occur in the IL@MOF systems, with ion-hopping prevailing for IL0.5@MOF and cooperative movement with ionic-liquid segments also possible.
Caveat: Mechanism is proposed from activation energies, conductivity trends and literature comparison rather than directly observed ion trajectories.
