Electrochemical control over stoichiometry via cation intercalation into Chevrel-phase sulphides (CuxMo6S8, x = 1–3)

This work presents a systematic investigation of the electrochemical intercalation of aqueous copper cations into the Chevrel phase (CP) Mo 6 S 8 and its effect on the host's electronic and structural characteristics as a function of stoichiometry.
