Chevrel phases of the type M/sub x/Mo/sub 6/S/sub 8-9/ (M = metal ion) are an important class of compounds because of their interesting structural, superconducting, and magnetic properties. Attempts are also being made to exploit the possibilities of their use as electrode material. Some investigators used bulk specimen or pellets of one of the Chevrel phases, copper molybdenum sulfides (CMS), as a rechargeable cathode material for lithium secondary batteries. A porous thin film of CMS would be suitable as an electrode in developing a high energy compact secondary battery. CMS thin films are usually prepared by a dc getter sputtering method or by an evaporation technique. However, films produced by any of these methods often contain an impurity phase other than the pure CMS phase. A new technique of preparing porous and coherent thin films of CMS on Cu/sub 2/S has been developed. The preparation technique and the properties of the film, along with the results of incorporation of Li/sup -/ ion into this film, are presented in this paper.
