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: Medium

PMo10V2-ILs@MIL-100 delivers superior cycling stability and rate capability among reported MOF-, POM- and POMOF-based crystal anode materials.

Caveat: Comparative literature table S5 is not available locally, so the broad 'best amongst reported' claim cannot be independently checked from supplied documents.

5 (journal p. 8739) · Results and discussion · Table S5 referenced · Linked to 5 structured results

CaveatSupport assessment: High

The authors note that synthesis of PMo10V2-ILs@MIL-100 is complex and ionic liquids are not cheap.

2 (journal p. 8736) · Introduction

Phase AssignmentSupport assessment: High

IL diffusion into PMo10V2@MIL-100 does not break the POMOF/MIL-100 crystalline structure.

Caveat: Structural schemes are in SI Fig. S2; no CIF was supplied in the assigned documents.

3 (journal p. 8737) · Results and discussion · Fig. 1a,b · Linked to 3 structured results

Structure Property LinkSupport assessment: High

PMo10V2-ILs@MIL-100 shows hybrid battery/supercapacitor lithium-storage behaviour, with capacitance and Li+ insertion/extraction both contributing.

Caveat: The b-value interpretation in the article appears reversed relative to common convention, but the extracted claim follows the authors' stated interpretation of mixed behaviour for b values between 0.5 and 1.

Structure Property LinkSupport assessment: Medium

Larger MIL-100 mesoporous cages and higher surface area improve capacitive contribution relative to PMo10V2-ILs@HKUST-1.

Caveat: Numerical surface-area values are in SI Fig. S3 discussion, and cage-size comparisons are in SI Fig. S12; pore-size distributions are graphical.

Transport MechanismSupport assessment: High

Encapsulated imidazolium ionic liquids improve ionic and electronic conductivity of PMo10V2@MIL-100, producing a much higher bulk conductivity and faster Li+ transport.

Caveat: Bulk-conductivity method is two-probe on pressed powders; detailed Table S1 and EIS fitting are in the SI.
