Lithium‐sulfur batteries (LSBs) are seriously impeded by poor reaction kinetics and the polysulfides shuttling, leading to low utilization of sulfur and poor cycling performance. Herein, amorphous MoS2/MoO3 nanosheets are prepared by a one‐step formamide (FA)‐assisted strategy. Due to the merits of high adsorption capability and good catalytic activity of MoS2, relatively high electronic conductivity and strong polarity of MoO3, and abundant active sites of amorphous nanosheet structure, the LSBs based on amorphous MoS2/MoO3‐2 nanosheets coated separator exhibit an outstanding specific capacity (1420.2 mA h g‐1 at 0.1 C), excellent rate capacity (505.4 mA h g‐1 at 5 C), and long cycle life (a negligible decay rate of 0.063 % per cycle at 0.5 C). This work provides an idea for designing efficient amorphous catalytic materials in LSBs.
