Abstract

A study was conducted, to demonstrate a partial substitution of sulfur by selenium atoms in Mo6S8-ySey Chevrel phases (CP) that enabled to elaborate fast cathodes for rechargeable magnesium batteries. The Mo6S8-nSen CPs were obtained from Cu2.5 Mo6S8-nSen precursors from which copper was leached in an oxygen-containing acid aqueous solution. The micro-metric sized stable phase Cu2.5 Mo6S 8-nSen materials were prepared by reacting stoichiometric mixtures of MoS2, MoSe2, molybdenum, and copper powder in evacuated quartz ampoules heated to 1150°C. The presence of selenium in the anionic framework of the CPs increased its polarizability, increasing the kinetics of the solid state diffusion of magnesium ions, while improving its performance.
