abstract = {Lithium sulfide (Li2S) has drawn much attention owing to its super-high theoretical specific capacity and energy density, as well as its compatibility with lithium-free anode materials. However, the commercialization of Li2S cathode is severely hindered by its poor rate capability and short cyclic life arising from its poor electrical conductivity, high activation energy barrier and shuttle effect of polysulfide intermediates. Many approaches have been reported, mainly focusing on the development of host for Li2S cathode as well as electrolyte engineering, which have achieved great progress. This review firstly provides an in-depth discussion of the challenges encountered Li2S cathode, subsequently discusses the host design for Li2S cathode and electrolyte engineering, focusing on the fundamental mechanism underlying the host or electrolyte engineering for improving the reaction kinetics and interface stability. Finally, the remaining challenges and future directions of Li2S cathode are discussed to further improve the performance of Li2S cathode materials and promote their practical application.}
