Webb25 feb. 2024 · Metal phosphides are of great interest in sodium-ion batteries due to their high capacity in theory and suitable redox potential. However, the large bulk expansion and sluggish diffusion kinetics greatly hinder their development. Herein, the electrochemical reaction kinetics of vanadium diphosphide (VP2) is Webb15 aug. 2013 · Sluggish diffusion kinetics is an important contributor to the outstanding properties of high-entropy alloys. However, the diffusion kinetics in high-entropy alloys has never been probed directly.

Sluggish diffusion in Co–Cr–Fe–Mn–Ni high-entropy alloys
Webb4 mars 2016 · As the diffusion of Mn in the CrMnFeCoNi HEA has been reported to be sluggish [ 1 ], it is of interest to determine whether this step controls the overall oxidation rate rather than diffusion through the oxide scale. To this end, we performed isothermal oxidation tests in air between 500 and 900 °C for times up to 100 h on the CrMnFeCoNi … WebbThe Sluggish Diffusion of Cations in CeO 2 Probed through Molecular Dynamics and Metadynamics Simulations.
