Lithium–sulfur (Li–S) batteries are considered as a substitute for conventional batteries as they are the most promising next‐generation energy‐storage system due to their high energy densities. However, their short cycling life, limited sulfur loading, severe polysulfide shuttling, and low sulfur utilization critically impede grid‐level‐storage energy techniques in Li–S batteries. The lithium shuttle effect results in rapid capacity fading and battery failure. The design and fabrication of sulfur hosts are key points to eliminate the aforementioned issues, especially the shuttle effect. In the past decade, spatial encapsulation and chemical interaction have improved the adsorption capacity of lithium polysulfides for the sulfur hosts and thus prolonged the lifetime of Li–S batteries. In an attempt to promote future research on the sulfur cathode and foster breakthroughs in Li–S batteries, recent achievements are highlighted, mechanical insights are discussed, and the remaining challenges and future research directions in the innovation of sulfur cathodes are identified.

硫寄主反对航天飞机的影响

锂硫(Li–S)电池由于其高能量密度而被认为是常规电池的最有希望的下一代储能系统。但是,它们的循环寿命短,硫载量有限,多硫化物的剧烈穿梭以及低硫利用率严重阻碍了Li-S电池的电网级储能技术。锂穿梭效应会导致快速的容量衰减和电池故障。硫基质的设计和制造是消除上述问题(尤其是穿梭效应)的关键。在过去的十年中,空间封装和化学相互作用提高了多硫化锂对硫主体的吸附能力,从而延长了Li-S电池的寿命。
