We have prepared ternary chalcostibite (CuSbS2) blocks by use of a facile one-pot solvothermal method at 180 degrees C in anhydrous ethylenediamine containing copper(I) chloride, antimony trichloride, and powdered sulfur as reactants. Time-dependent experiments were performed to investigate the mechanism of growth and evolution of the morphology of CuSbS2, which was characterized by x-ray powder diffraction and field-emission scanning electron microscopy. The novel ternary CuSbS2 was also investigated as an electrode material for lithium ion batteries. Study of its electrochemical properties revealed a high initial lithium ion storage capacity of 877.6 mAh g(-1), indicative of potential as an electrode material for lithium ion batteries.
