摘　　要：Lithium-sulfur batteries are considered as one of the potential solutions as integrating renewable energy systems for large-scale energy storage because of their high theoretical energy density(2600 Wh·kg^(-1))and specific capacity(1675 mAh·g^(-1)).Currently,various strategies have been proposed to overcome the technical barriers,e.g.,“shuttle effect”,capacity decay and volumetric change,which impede the successful commercialization of lithium-sulfur batteries.This paper reviews the applications of metal nitrides as the cathode hosts for high-performance lithium-sulfur batteries,summa-rizes the design strategies of different host materials,and discusses the relationship between the properties of metal nitrides and their electrochemical performances.Finally,reasonable suggestions for the design and development of metal nitrides,along with ideas to promote future breakthroughs,are proposed.We hope that this review could attract more attention to metal nitrides and their derivatives,and further promote the electrochemical performance of lithium-sulfur batteries.由于锂硫电池高理论能量密度 (2600 Wh·kg^(-1)) 和比容量 (1675 mAh·g^(-1)) , 被认为是集成可再生能源 系统用于大规模能量存储的潜在解决方案之一。但由于“穿梭效应”、容量衰减和体积变化等障碍阻碍了 锂硫电池的成功商业化。现阶段已提出各种策略以克服技术障碍, 本文综述了不同金属氮化物作为高性 能锂硫电池阴极宿主材料的应用, 总结了不同宿主材料的设计策略, 讨论了金属氮化物性质与其电化学 性能之间的关系, 最后, 提出了对金属氮化物设计和发展的合理建议, 以及促进未来突破的想法。我们希 望本文能够引起更多关于金属氮化物及其衍生物的关注, 并进一步促进锂硫电池的电化学性能 。
