| 中文摘要 | The most-popular strategy to improve the cycling stability and rate performance of the sulfur electrode in lithiumsulfur (LiS) batteries is to astrict the sulfur in a conducting medium by using complicated chemical/physical processing. Lithium sulfide (Li2S) has been proposed as an alternative electrode material to sulfur. However, for its application, it must meet challenges such as high instability in air together with all of the drawbacks of a sulfurcontaining electrode. Herein, we report the feasibility of using Li2S, which was obtained by electrochemical conversion of commercial molybdenum disulfide (MoS2) into Li2S and metallic molybdenium (Mo) at low voltages, as a high-performance active material in LiS batteries. Metallic Mo prevented the dissolution of lithium polysulfides into the electrolyte and enhanced the conductivity of the sulfide electrode. Therefore, the in situ electrochemically prepared Li2S/Mo composite exhibited both high cycling stability and high sulfur utilization. |
