摘要

Antimony sulfide (Sb_2S_3) is a promising electrode material. However, its poor electronic/ionic conductivity severely hinders its practical application. Herein, carbon-coated Sb_2S_3 nanorods (Sb_2S_3@C) are synthesized to address this issue. The electrochemical performance of the Sb_2S_3@C is evaluated in allsolid- state lithium batteries (ASSLBs) using InLi anode and Li_(10)Si_(0.3)PS_(6.7)Cl_(1.8) solid-state electrolytes. The Sb_2S_3@C cathode delivers the 1st cycle discharge capacity of 711 mAh g-1 and a stable cycling capacity of 431 mAh g-1, which are much higher than the 1st cycle discharge capacity of 125 mAh g-1 and a stable cycling capacity of 320 mAh g-1 for the uncoated Sb_2S_3 cathode. In situ transmission electron microscopy reveals that the carbon coating layer acts as an electronic/ionic conductive conduit, which boosts the charge transfer in the electrode dramatically. Consequently, the Sb_2S_3@C electrochemistry quickly evolves from intercalation to conversion to full alloying. However, the Sb_2S_3 nanorods without carbon coating undergo sluggish intercalation and conversion reactions, and the alloying reaction is almost impeded, severely limiting the capacity. Therefore, the Sb_2S_3@C electrode is fully utilized thus delivering much higher capacity and rate performance than the non-coated Sb_2S_3 electrode. These results demonstrate that Sb_2S_3@C is a promising high-energy-density cathode for ASSLBs.
