Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
Ex situ XRD indicates Li+ insertion does not greatly influence the Ni3(HITP)2 crystal structure.
Caveat: Rendered SI Figure S3 supports the before/after-charge comparison, but no quantitative Rietveld refinement or operando diffraction is provided.
2 · Supplementary data · Figure S3 · Linked to 1 structured result
Ni3(HITP)2 is presented as a 2D conductive MOF with a large d-pi electron conjugation system that benefits electron conduction and electrolyte wetting.
Caveat: No direct electrical conductivity measurement is reported in the article; conductivity is inferred from material identity/conjugation and prior literature.
7 · Conclusion · Linked to 5 structured results
Spindle-like nanofibre morphology and porous 2D structure are proposed to mitigate volume expansion and support cycling stability.
Caveat: The causality is argued from morphology retention and electrochemical performance; no direct strain/volume-expansion measurement is provided. Figure S2 CE value is a visual estimate.
5 · Results and discussion · Fig. 4f; Figure S4 · Linked to 5 structured results
The Li+ storage capacity is attributed to redox participation of Ni2+ and amino/imine nitrogen sites plus capacitive contribution from framework pores.
Caveat: Mechanistic assignment combines ex situ XPS, CV kinetic analysis, and molecular DFT rather than direct operando structural evidence.
