Structure and electrochemistry of LixMo6S8

Abstract

The Chevrel compound ${\mathrm{Li}}_{\mathrm{x}}$ ${\mathrm{Mo}}_6$ ${\mathrm{S}}_8$ has four phases for 0<x<1: two rhombohedral phases, a rhombohedral phase with an incommensurate lattice distortion, and a triclinic phase. The lattice parameters in each phase have been measured, and the transitions between the phases have been studied with the use of intercalation batteries.
