Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
The NiCo-MOF-3//MnO2 flexible FASC reaches high energy density and power density compared with previously reported MOF-based supercapacitors.
Caveat: Comparative literature values in Table 4 are not first-hand evidence for this extraction, except the 'this work' row.
15298 / p012 · 3.3 Electrochemical Performance of the Asymmetric Supercapacitor · Tables 3 and 4 · Linked to 3 structured results
K3[Fe(CN)6] in the PVA/KOH gel broadens the FASC operating potential to 1.6 V and improves capacitance through Fe(CN)6 redox pseudocapacitance.
Caveat: Device without K3[Fe(CN)6] is shown graphically; exact capacitance values for the no-additive device are not tabulated in the main text.
15298 / p012 · 3.3 Electrochemical Performance of the Asymmetric Supercapacitor · Figure 10a,b · Linked to 2 structured results
Glycerin forms hydrogen bonds with PVA chains, suppresses ice-crystal formation at low temperature, and supports operation from -20 to 40 deg C.
Caveat: Temperature performance is shown as CV/GCD curves without tabulated capacitance retention values at each temperature.
15299 / p013 · 3.3 Electrochemical Performance of the Asymmetric Supercapacitor · Figure 11d-f · Linked to 2 structured results
Mutual substitution, coordination, and cooperation of Ni and Co lower internal/charge-transfer resistance and improve electrochemical performance compared with single-metal MOFs.
Caveat: The reported R1 text gives 0.7407 ohm for NiCo-MOF-3 in one passage, while Tables 1 and 2 list 0.776 ohm; table value is used for database results.
15296 / p010 · 3.2 Electrochemical Performance of Electrodes · Figure 7 and Table 1 · Linked to 4 structured results
The Ni:Co ratio controls NiCo-MOF morphology, and NiCo-MOF-3 provides the most favourable raspberry-like nanoscale-rod structure for electrochemical performance.
Caveat: Surface-area plots are in the supplied SI; main text reports the numerical BET values.
15292 / p006 · 3.1 Morphologies and Compositions · Figures 4 and 5 · Linked to 3 structured results
Co incorporation in NiCo-MOF-3 brings electronic states closer to the Fermi level, strengthens orbital hybridisation near the Fermi level, and improves electron transport/redox kinetics relative to Ni-MOF.
Caveat: Electrical conductivity is inferred from DFT and EIS; no direct four-probe or bulk conductivity value is reported.
