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

Li@Zn-MOF-74/Li-IL combines high ionic conductivity, high transference number, and stable battery cycling with LiFePO4 and LiCoO2 cathodes at 30 C.

Caveat: Battery tests used small coin cells and about 5 uL Li-IL added to cathode for porous-cathode ion diffusion.

article p.12 · Conclusion · Linked to 4 structured results

Composite RoleSupport assessment: High

Li-IL binder is required to provide interparticle ion diffusion; binder-free Li@MOF pellets showed open-circuit-like high resistance.

Caveat: Pure Li@MOF conductivities are reported qualitatively as huge bulk resistance rather than tabulated values.

SI p.S-93 · Supplementary Note regarding pure Li@MOF electrolytes · Figures S75-S77 · Linked to 2 structured results

Structure Property LinkSupport assessment: High

MOF electrolytes with non-redox-active metal sites show wider electrochemical stability windows than analogues with redox-active metal centres.

Caveat: Stability windows are thresholded by +/-5 uA cm-2 LSV/CV criteria and depend on electrolyte composition.

article p.4 · Stability and Ion-Transport Properties · Figure 3g · Linked to 4 structured results

Structure Property LinkSupport assessment: High

Pore aperture governs LiTFSI uptake, which in turn controls ionic conductivity across the Li@MOF/Li-IL electrolyte series.

Caveat: DME uptake and open-metal-site interactions also influence solvation and transport.

article p.8 · Solvation Structures · Figure 5 · Linked to 6 structured results

Transport MechanismSupport assessment: High

Open metal sites dissociate LiTFSI and immobilise TFSI- anions while allowing solvated Li+ transport, increasing transference number.

Caveat: Cluster DFT models simplify pore steric effects; XANES cannot distinguish whether TFSI- or DME coordinates to Zn2+.

article p.11 · Li-Ion Transport in MOFs · Figure 7 · Linked to 4 structured results

Transport MechanismSupport assessment: Medium

Solvated Li+ ions diffuse faster via a DME vehicle mechanism than de-solvated ions via hopping in Li@MOFs.

Caveat: T1 is an indirect mobility proxy; AIMD production length was 50 ps.
