The effect of the anionic framework of Mo6X8 Chevrel phase (X=S, Se) on the thermodynamics and the kinetics of the electrochemical insertion of Mg2+ ions

Levi MD, Lancri E, Levi E, Gizbar H, Gofer Y, Aurbach D

The absence of Mg-ion trapping in selenium-based Chevrel phase (in contrast to charge trapping in MgxMo6S8) was carefully monitored using a combination of three electroanalytical tools: SSCV, PITT and EIS. We discuss the difference between MgxMo6S8 and MgxMo6Se8 (0
