Abstract

A study was conducted, to demonstrate a partial substitution of sulfur by selenium atoms in Mo₆S_8-ySe_y Chevrel phases (CP) that enabled to elaborate fast cathodes for rechargeable magnesium batteries. The Mo₆S_8-nSe_n CPs were obtained from Cu_2.5 Mo₆S_8-nSe_n precursors from which copper was leached in an oxygen-containing acid aqueous solution. The micro-metric sized stable phase Cu_2.5 Mo₆S _8-nSe_n 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.
