Monodispersed copper phosphide nanocrystals in situ grown in a nitrogen-doped reduced graphene oxide matrix and their superior performance as the anode for lithium-ion batteries

Abstract

A nanocomposite anode material consisting fully of monodispersed copper phosphide (Cu3P) nanocrystals in situ grown into three dimensional (3D) nitrogen-doped reduced graphene oxide (N-RGO) matrixes has been manufactured in the...

Significant differences in the electrochemical activity of black phosphorus anodes prepared under different atmospheres

“…With these Cu 3 P diffraction peaks and EDX, ICP-OES measurements described above, it can be concluded that the BP has reacted with the copper current collector, forming a new Cu 3 P phase in the BP-Air anode. Extensive studies have shown that Cu 3 P holds a stable electrochemical activity 15 and relatively small volume changes. The presence of the Cu 3 P phase may mitigate the pulverization of BP particles, allowing the active debris particles to remain in contact, as observed in Fig.…”
