To satisfy the demand for efficient energy storage employed in smart grids, electric vehicles and renewable energies, development of novel battery systems with remarkable specific
capacity, low-cost and eco-friendly becomes an imminent task for researchers. Compared with the traditional lithium ion batteries (LIBs), lithium-sulfur (Li-S) batteries have attracted increasing attention as the next-generation energy storage devices, owing to their extremely high theoretical specific capacity (1675 mAh g ?1) and energy density (2600 Wh kg ?1) of sulfur. In addition, sulfur is low-cost, earth abundant and eco-friendly, making this system
attractive for large scale applications.1 Despite these considerable advantages, the commercialization of Li-S battery is slowed down by several technical limitations. First, the poor intrinsic conductivity of pristine sulfur results in low utilization of sulfur cathode;2 second, the dissolution and migration of polysulfide intermediates produced during electrochemical reactions leads to the loss of active mass.
