摘要：

The shuttle effect and the slow conversion kinetics hinder the practical application of lithium-sulfur batteries. Herein, we synthesized the polypyrrole (PPy) coated defect-rich MoS2 nanoflowers (PPy@DR-MoS2) as sulfur host. Benefiting from the sulfur defects and PPy coating structure, the S/ppy-DR-MoS2 composite displays good cycling performance at a high current density of 1C and excellent cycling stability for over 300 cycles with a low cycling decline rate of 0.17% per cycle.
