Abstract
Cathodic reduction of MoS2 in DMSO electrolytes containing alkali cations A+ results in the formation of defined ternary phases A+0.125 (DMSO)y[MoS2]0.125- with highly mobile solvated interlayer cations. Reduction of MoS2 in DME electrolytes yields similar products. Basal spacings are dependant on solvent type and on ionic radius of A+. Further reduction of these compounds is associated with irreversible processes.
