Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
NiP2@C is presented as a high-performance lithium-ion battery anode with high reversible capacity, rate capability, and cycling stability.
Caveat: Performance is measured in half-cells and includes conductive Super-P/PVDF electrode formulation.
6 · Conclusions · Linked to 4 structured results
The paper states that porous carbon enhances electronic conductivity, but it does not report a standalone electronic conductivity, Seebeck coefficient, or thermoelectric measurement.
Caveat: Transport evidence is limited to electrochemical impedance in a battery electrode context.
1 · Abstract · Linked to 2 structured results
Small monodisperse NiP2 nanoparticles in porous carbon alleviate mechanical strain, improve lithium-ion accessibility, and support high reversible capacity.
Caveat: Mechanistic relationship is inferred by authors from morphology, porosity, and electrochemical performance; no direct strain measurement is reported.
3 · Results and discussion · Fig. 2-3 · Linked to 5 structured results
Ni-MOF-74 can use adsorption of red phosphorus plus calcination to yield nanostructured NiP2@C, with Ni(II) ions converted to nickel phosphide and organic linkers carbonised to porous carbon.
Caveat: Red-phosphorus-loaded intermediate is not independently characterised in the supplied text/images.
2 · Results and discussion · Scheme 1 · Linked to 3 structured results
The in situ porous carbon coating/matrix enhances electronic transport and lowers charge-transfer resistance during cycling.
Caveat: No four-probe electronic conductivity value is reported; support comes from EIS charge-transfer resistance and qualitative discussion.
4 · Results and discussion · Fig. 4b · Linked to 2 structured results
The electrode undergoes a reversible conversion reaction NiP2 + 6Li+ + 6e- -> 2Li3P + Ni0 on discharge, with NiP2 reforming on charge.
Caveat: Mechanistic equation is reported by the authors from ex situ XPS/XRD/SAED evidence.
