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@NOCA@CF enables stable carbonate-electrolyte Li symmetric cells and improved LNMO/NCM full-cell cycling.

Caveat: LCO/LMO/LFP full-cell data are supplied only as SI figure captions without numeric text values in the text layer.

Application RelevanceSupport assessment: High

NOCA@CF also functions as a binder-free self-standing lithium-ion battery anode with high reversible capacity, rate capability, and long-term cycling stability.

Caveat: SI provides text-reported values but no rendered SI pages were supplied for visual verification.

rendered SI text · Figs. S17-S20 narrative · Figs. S17-S20 · Linked to 3 structured results

CaveatSupport assessment: High

The rendered SI comparison tables contain apparent source-label inconsistencies in the this-work Li symmetric rows, so table-derived Li@NOCA@CF comparison values should be used with their raw labels and caveats rather than as independent electrolyte identity proof.

Caveat: Table S2 and S3 this-work rows visibly print Zn@NOCA@CF; Table S3 also prints 1M LiTFSI DD despite being headed as carbonate electrolyte.

CaveatSupport assessment: High

The paper asserts high electronic conductivity for NOCA@CF but does not report a direct electrical conductivity measurement.

Caveat: Conductivity is inferred from graphitization and electrochemical performance rather than measured as a transport value.

7 · 3.1. Synthesis and characterization of NOCA@CF · Fig. 2d · Linked to 1 structured result

Phase AssignmentSupport assessment: High

NOCA@CF retains the nanorod morphology of the ZIF-8@CF precursor and becomes a porous N/O-doped carbon nanosheet/nanorod array.

6 · 3.1. Synthesis and characterization of NOCA@CF · Fig. 1d-m · Linked to 4 structured results

Structure Property LinkSupport assessment: High

NOCA@CF stabilizes Li plating/stripping in ether electrolyte, yielding higher CE and longer symmetric-cell cycling than CF.

10 · 3.3. Electrochemical performance in ether-based electrolyte · Fig. 5; Fig. 6 · Linked to 7 structured results

Structure Property LinkSupport assessment: High

NOCA@CF improves aqueous Zn plating reversibility and suppresses Zn dendrites relative to bare CF.

Caveat: Some morphology support is visual/qualitative.

9 · 3.2. Electrochemical performance of NOCA@CF for Zn metal anode · Fig. 3; Fig. 4 · Linked to 7 structured results

Synthesis MechanismSupport assessment: High

Vacuum distillation converts ZIF-8@CF into NOCA@CF while evaporating/recycling Zn, avoiding additional acid etching and helping carbonization/graphitization.

Caveat: Main text contains a 12 h versus 24 h inconsistency for ZIF-8 growth time.
