摘要	Lithium-sulfur batteries are considered the most promising candidates in the next generation of electrochemical energy storage because of their huge advantages in energy density, coulombic efficiency and price. One of the problems to be solved is promoting the conversion of polysulfides while maintaining high sulfur utilization. Complex double-layered hollow nanostructures have attracted wide attention as battery cathode materials. A ZIF-67 nanocube is used as a template to form a double-layer hollow structure (denoted as CoS) in which the inner layer is a CoS nanobox and the outer shell is a CoS nanosheet. In general, the double-layer hollow structure not only maximizes the encapsulation of sulfur but also provides sufficient reaction sites to optimize the electrochemical properties of the material. As a cathode material for Li-S batteries, cobalt-based sulfides also improve electrochemical performance due to their high electronic conductivity and abundance of redox reaction sites. The initial discharge capacity of the battery at 0.1 C was 1275.76 mA h g(-1), demonstrating excellent rate performance.
