Author interpretations and caveats

Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.

Application RelevanceSupport assessment: High

ZIF-PIO improves Li-S battery rate capability, cycling retention and charge-transfer resistance compared with PE and PIO separator controls.

Caveat: Application performance depends on rGO/S cathode and electrolyte conditions as well as separator.

7-8 · Results and Discussion · Figure 5/S16 · Linked to 5 structured results

CaveatSupport assessment: Medium

Although ZIF-PIO suppresses Li dendrite formation during cycling, Li-metal anode degradation remains a long-term limitation after extended cycling.

Caveat: Based on post-cycling SEM descriptions; numerical dendrite metrics are not reported.

Phase AssignmentSupport assessment: High

The in situ grown coating on PIO is assigned to ZIF-67 because XRD peaks match pure/simulated ZIF-67 and EDS mapping identifies cobalt.

Caveat: Pure ZIF-67 reference synthesis recipe not reported in the available text.

Structure Property LinkSupport assessment: High

The inverse-opal PEEK structure provides high electrolyte uptake and interconnected ion pathways, while ZIF-67 improves Li+ selectivity and lowers transport resistance.

Caveat: PE/PIO conductivity and transference controls are partly estimated from Figure 3 axes.

Transport MechanismSupport assessment: High

ZIF-PIO accelerates Li2S nucleation and dissolution, consistent with improved polysulfide redox kinetics.

Caveat: Only PE numeric controls are given in the text for nucleation and dissolution timing.

11 · Results and Discussion · Figure S23 · Linked to 2 structured results

Transport MechanismSupport assessment: High

Co sites and imidazole chemistry in the ZIF-67 layer adsorb/catalyse LiPS species, suppressing shuttle current and LiPS diffusion.

Caveat: Some shuttle-current magnitudes are graphical estimates; UV-vis adsorption is reported qualitatively.
