Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
HAN-Cu-MOF combines high capacity, high-rate performance, and long cycling stability as a high-temperature K-ion battery anode.
Caveat: Performance is in half-cells against potassium metal; practical full-cell data were not reported in the extracted documents.
6754 · Introduction · Figure 2 · Linked to 4 structured results
Pi-d conjugation between HAN units and CuO4 nodes gives delocalised electron distribution, enhancing electronic conductivity and chemical stability.
Caveat: Conductivity is still semiconductive and measured on pressed powder pellets, not single-crystal or oriented films.

DFT supports accessible O and N binding regions and a two-step K+ accommodation process while retaining pore structure.
Caveat: Simulation used a pore model and adopted Cu +1 throughout; only inner pore potassiation sites were exhibited.

Reticular framework construction mitigates the dissolution problem of small-molecule organic electrodes at elevated temperature.
Caveat: Solubility result is qualitative visual evidence.
6758 · Results and Discussion · Figure 4e · Linked to 3 structured results
C=N, C=O, and CuO4 units act as reversible redox-active sites for K-ion storage.
Caveat: Assignments are based on ex situ spectroscopy and mechanistic interpretation rather than in situ structural refinement.
6759 · Results and Discussion · Figure 5 · Linked to 7 structured results
K-ion storage in HAN-Cu-MOF is surface-dominated/capacitive, enabling fast K+ transfer and low strain.
Caveat: Capacitive contribution values are reported as ranges over scan rates rather than a single universal value.
