Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
UIOSOL@PP improves Li metal battery CE, Li|Li overpotential stability, LFP|Li rate/cycling performance and NCM523|Li cycling relative to PP.
Caveat: Supplementary EIS resistance values are captured from rendered SI Table S2.
6 · Conclusions · Fig. 5; Fig. 6 · Linked to 9 structured results
The UIO-SOLi/PAA coating improves separator wettability, thermal stability and electrochemical stability while maintaining a thin coating.
Caveat: Thermal and toughness images are in rendered SI; contact angles were read from figure labels.
3 · Result and discussion · Fig. 2; Fig. 3a; Fig. S5-S8 · Linked to 6 structured results
Introducing BDC-NaSO3 and exchanging Na+ for Li+ does not change the crystallinity or morphology of the UiO-66 framework.
Caveat: CIF/structural refinement not supplied; assignment relies on PXRD/FTIR/SEM in main text.
2 · Result and discussion · Fig. 2a-c · Linked to 4 structured results
Sulfonate introduction lowers UiO porosity relative to UIO-66, while Li exchange slightly restores area and pore volume relative to UIO-SOH.
Caveat: Only BET and pore volume values are reported; pore-size distribution needs SI/figures.
2 · Result and discussion · Fig. 2d · Linked to 6 structured results
Higher Li+ transference and lower anion transport with UIOSOL@PP regulate Li-ion flux, suppress dendritic/loose Li growth and reduce side reactions.
Caveat: Morphology/XPS evidence is largely qualitative; full cycling post-mortem details are partly in SI.
5 · Result and discussion · Fig. 4; Fig. 5c-f · Linked to 6 structured results
COMSOL simulations indicate the UIOSOL@PP separator lowers the anion concentration gradient at the end of discharge from 1.2 M to 0.8 M.
Caveat: Model parameters are captured from rendered SI Table S3; simulation remains supporting evidence rather than direct measurement.
6 · Result and discussion · Fig. 6d,e; Table S3 · Linked to 7 structured results
Negatively charged SO3- groups in UIO-SOLi repel anions and facilitate Li+ transport, raising tLi+ and Li+ conductivity.
Caveat: EIS fitting inputs are now captured from rendered SI Table 1; absolute zeta potentials are approximate figure-axis reads.
