Orthorhombic Sb2S3 (stibnite) and its amorphous Sb2S3/C composite were synthesized by solid-state routes, such as heat treatment and high energy mechanical milling (HEMM). X-ray diffraction, X-ray photoelectron spectroscopy and high resolution transmission electron microscopy confirmed that the amorphous Sb2S3/C composite was composed of amorphous Sb2S3 phases distributed uniformly within an amorphous carbon matrix. The electrochemical reaction mechanism of amorphous Sb2S3/C with Li was examined by extended X-ray absorption fine structure analyses. The fabricated amorphous Sb2S3/C composite electrode showed excellent electrochemical properties, such as a high energy density (1st charge: 757 mAh g-1), long cyclability (ca. 600 mAh g-1 over 100 cycles), and good initial Coulombic efficiency (ca. 85%). When tested within various voltage windows, the amorphous Sb2S3/C composite electrode was found to be suitable for use as a dual electrodes, such as the anode in Li-ion batteries or the cathode in Li/S batteries.
