Bi2S3 is a promising negative electrode material for lithium storage owing to its high theoretical capacity. Nevertheless, the capacity of Bi2S3 decays very rapidly upon Li cycling. Here, Bi2S3 and Bi2S3/C were successfully synthesized by a novel route. Sulfur powder as a kind of sulfur source reacted with a metal organic framework based on bismuth and trimesinic acid—Bi(BTC)(DMF)·DMF·(CH3OH)2 (denoted as Bi-BTC). Trimesic acid further acted as a new type of carbon source to synthesize the Bi2S3/C composite. The particle sizes of the composite were smaller than those of pure Bi2S3, showing the suppression of Bi2S3 aggregation. Charge–discharge performance and cyclability for both the Bi2S3 and Bi2S3/C composites in lithium-ion batteries were measured. Specifically, the specific capacities of Bi2S3/C and Bi2S3 reached 765 and 603 mA h g−1, respectively, at 100 mA g−1 after 100 cycles. Because of its high capacity and excellent cycle life, Bi2S3/C is a promising energy storage material.

Bi 2 S 3 / C纳米棒可作为锂离子电池的高效负极材料†
Bi 2 S 3由于其高理论容量而成为有希望的用于锂存储的负极材料。然而，Bi 2 S 3的容量在Li循环时非常迅速地衰减。在这里，Bi 2 S 3和Bi 2 S 3 / C通过一种新颖的途径成功地合成了。硫粉作为一种硫源，与基于铋和偏苯三酸的有机金属骨架Bi（BTC）（DMF）·DMF·（CH 3 OH）2（表示为Bi-BTC）反应。三甲磺酸进一步充当合成Bi 2 S 3的新型碳源/ C复合。复合材料的粒径小于纯Bi 2 S 3的粒径，显示出对Bi 2 S 3聚集的抑制。测量了锂离子电池中Bi 2 S 3和Bi 2 S 3 / C复合材料的充放电性能和可循环性。具体而言，Bi 2 S 3 / C和Bi 2 S 3的比容量在100个循环后在100mA g -1下分别达到765和603mA hg -1。由于其高容量和出色的循环寿命，Bi 2 S3 / C是一种很有前途的储能材料。
