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

Ni-DBH shows the strongest long-cycle Li-ion stability after voltage-window optimisation.

Caveat: This claim is based on the adjusted 1.5-3.2 V window, not the common 1.5-3.5 V 0.5 C comparison.

Application RelevanceSupport assessment: High

S@Mn-DBH has the best Li-S capacity maintenance and catalytic activity among the three sulfur-loaded electrodes.

Caveat: Best performance depends on metric: Co has faster diffusion and higher restored rate capacity, while Mn has lower Delta E and stronger long-cycle capacity maintenance.

Composite RoleSupport assessment: Medium

Layered porosity is proposed to provide uniform sulfur distribution and a physical barrier for polysulfide transport during Li-S cycling.

Caveat: The barrier role is inferred from electrochemical behaviour and porosity, not directly measured polysulfide transport.

Structure Property LinkSupport assessment: High

The triptycene-based 3D molecular extension and AB-staggered stacking provide more accessible MO4 active sites for electrolyte contact.

Caveat: The direct comparison to planar 2D c-MOFs is literature-based rather than a same-paper synthetic control.

p009 · Conclusion · Linked to 3 structured results

Transport MechanismSupport assessment: High

S@Co-DBH promotes soluble polysulfide migration and has the fastest Li-ion diffusion rate among the sulfur-loaded electrodes.

Caveat: Diffusion coefficients are calculated from CV slopes using the Randles-Sevcik equation; one reduction-stage value is read from the figure.
