Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
The ILE@MOF electrolyte enables lithium-metal cells to operate at high temperatures up to 150 deg C across LiFePO4, NMC111, NMC811 and Li4Ti5O12 configurations.
Caveat: Application results are coin-cell demonstrations; long-cycle high-temperature results vary by cathode chemistry.

ILE@MOF is thermally stable and non-flammable under the reported Bunsen-burner test, supporting safer high-temperature battery operation.
Caveat: Flammability result is a pass/fail test rather than a standardised heat-release measurement.

ILE@MOF protects lithium metal by forming a particle-rich coating on the Li anode, suppressing dendrite growth and stabilising high-temperature stripping/plating.
Caveat: Dendrite suppression is supported by SEM and cell cycling; quantitative dendrite statistics are not reported.

ZIF-67 remains structurally intact after ILE loading.
Caveat: Based on powder XRD peak retention; no CIF/refinement supplied.

TFSI anions interact with Co sites in the MOF, weakening Li+ coordination and increasing free/mobile Li+ concentration, which improves ionic conductivity.
Caveat: Mechanistic interpretation is inferred from spectroscopy and conductivity trends; no direct Li transference number is reported.
