Open a family to keep every result attached to its sample, method and conditions.
Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
The M-NMN-1//AC battery-supercapacitor hybrid device delivers high energy density and long-cycle retention compared with similar two-electrode systems.
Caveat: Comparison is taken from the authors' Table 1; device-level result includes non-MOF activated carbon negative electrode.
main p.10, article p.20829 · Table 1 and Conclusion · Table 1 · Linked to 3 structured results
The M-NMN-1 sample with Ni:Mo = 1:1 gives the best electrochemical performance among Ni-MOF, M-NMN-1, M-NMN-2 and M-NMN-3.
Caveat: The synthesis feed amounts are incomplete, and actual Ni/Mo ratios for M-NMN-2 and M-NMN-3 are only described qualitatively from SI Fig. S1.
main p.5, article p.20824 · Electrochemical performance · Fig. 5 · Linked to 5 structured results
Mo-based clusters anchored/encapsulated in Ni-MOF channels improve conductivity and structural stability relative to pristine Ni-MOF.
Caveat: Conductivity is inferred from EIS charge-transfer/solution impedance and electrochemical performance; no direct electronic conductivity value is reported.
main p.2, article p.20821 · Introduction · Linked to 4 structured results
Increasing Mo doping leads to more serious nanosheet stacking, burying active sites and reducing charge-transfer/electrochemical performance.
Caveat: Stacking severity is qualitative from SEM images; no quantitative stacking metric is reported.
main p.5, article p.20824 · Electrochemical performance · Fig. 5 · Linked to 4 structured results
The large nanosheet/nanorod architecture acts as a charge-transport pathway, shortens ion/electron diffusion paths and accelerates charge storage.
Caveat: Mechanistic language is inferred from morphology plus electrochemical kinetics; no direct spatially resolved charge-transport measurement is reported.
