Abstract

Chevrel phases (CPs), M_xMo₆T₈ (M - metal, T = S, Se), may be used as unique cathode materials for rechargeable Mg batteries because of the high mobility of multivalent cations. However, the electrochemical behavior is strongly affected by the host composition. For the selenide, the intercalation process is completely reversible, while partial Mg trapping occurs upon its extraction from the sulfide at room temperature. These peculiarities of the electrochemical behavior were understood based on the analysis of the crystal structure of intercalation compounds, Mg _xMo₆T₈ (T = S, Se) determined by a combination of ab initio calculations and experimental methods (high resolution neutron and powder X-ray diffractions). copyright The Electrochemical Society.
