A simple and novel method based on recrystallization-sulfurization method has been developed to fabricate Ce2S3/MoS2 composite and their structure, morphology and electrochemical performance is researched systematically. The Ce2S3/MoS2 composite exhibit enhanced electrochemical performance compared with Ce2S3 and MoS2. Among them, Ce2S3/MoS2 composite has an initial reversible discharge capacity of 187.5 mAh g−1, coulombic efficiency of 78.6% and a reversible capacity as high as 636.5 mAh g−1, coulombic efficiency of 99.7% after 500 cycles at a current density of 100 mA g−1 and the highest discharge capacity of 97.3 mAh g−1 at a high current density of 1000 mA g−1, showing the best reversible capacity and cycling performance. The results show that the compositing between MoS2 and Ce2S3 can maintain the stability of the structure during the charge/discharge process and existence of Ce2S3 can enhance the electrical conductivity of Ce2S3/MoS2 composite and further improves the reversible capacities, cycling performance and rate performance of Ce2S3/MoS2 composite.
