摘　　要：Due to the high theoretical specific capacity(1675 mAh·g^(-1)),low cost,and high safety of the sulfur cathodes,they are expected to be one of the most promising rivals for a new generation of energy storage systems.However,the shuttle effect,low conductivity of sulfur and its discharge products,volume expansion,and other factors hinder the commercialization of lithium-sulfur batteries(LSBs).The development of sulfur-fixing materials and the design of multifunctional materials to enhance the electrochemical performance of LSBs have been the main research priorities in recent years.Because of the advantages of high conductivity,built-in electric field,and good synergism,more and more researchers have employed heterostructure into sulfur-fixing materials to enhance the catalytic and absorption ability for polysulfides.In this review,the principle of heterostructure and the mechanism of enhancing the performance of lithium-sulfur batteries are described.The applications of heterostructure in cathode and interlayer of LSBs in the latest years are summarized.Finally,the cutting-edge troubles and possibilities of heterostructures in LSBs are briefly presented.
