“…However, the severe shuttle effect and dendrite growth, and the inferior Coulombic efficiency that characterize these Li‐S batteries have greatly limited their lifespan 4, 8, 9, 10. Although much effort has been expended in the development of novel sulfur‐host electrodes,11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36 separators,37, 38, 39, 40 and electrolytes41, 42, 43, 44, 45 to resolve these issues, some of which are rather dangerous, the results have been at best minimal in improving current Li‐S battery technology. As a result, the cycling life and Coulombic efficiency of Li‐S batteries, especially in the high‐rate regime, are still far behind the state of the art in lithium‐ion battery technology.…”

Although the reversible and inexpensive energy storage characteristics of the lithium–sulfur (Li‐S) battery have made it a promising candidate for electrical energy storage, the dendrite growth (anode) and shuttle effect (cathode) hinder its practical application. Here, it is shown that new electrolytes for Li‐S batteries promote the simultaneous formation of bilateral solid electrolyte interfaces on the sulfur‐host cathode and lithium anode, thus effectively suppressing the shuttle effect and dendrite growth. These high‐capacity Li‐S batteries with new electrolytes exhibit a long‐term cycling stability, ultrafast‐charge/slow‐discharge rates, super‐low self‐discharge performance, and a capacity retention of 94.9% even after a 130 d long storage. Importantly, the long cycle stability of these industrial grade high‐capacity Li‐S pouch cells with new electrolytes will provide the basis for creating robust energy dense Li‐S batteries with an extensive life cycle.

“…38 The resulting mesoporous TiN-S cathode delivered much better cycling stability and rate capability than both mesoporous TiO 2 -S and Vulcan C-S cathode. The excellent overall electrochemical performance of a TiN-S cathode can be attributed to the good conductivity, robust framework of TiN, and the strong interactions between TiN and polysulphides.…”

“…Recently, to increase the tap density of electrodes as well as to keep long cycle life-span, nanostructured polar metal compounds, such as metal oxides, 33,34 metal hydroxides, 13 metal sulphides, 35,36 metal carbides, 37 metal nitrides, 38 and metal organic frameworks (MOFs), 39 have been used as the host materials toward (poly)sulphides.

Lithium-sulphur (Li-S) batteries are one of the most promising candidates for the next generation of energy storage systems to alleviate the energy crisis. However, Li-S batteries' commercialization faces the challenges of low active materials utilization, poor cycling life, and low energy density. Recently, tremendous progress has been achieved in improving the electrode performances and tap density by using the nanostructured metal compounds in Li-S batteries. In this review, we not only present the latest various nanostructured metal compounds applications in Li-S batteries, including metal oxides, metal sulphides, metal carbides, metal nitrides, and metal organic frameworks, but also we focus on the interaction mechanisms between these polar metal compounds with polysulphides. The issues and bottlenecks of these metal compounds are concluded and the corresponding available solutions to address these issues are proposed. This systematic discussion and proposed strategies can offer avenues to the practical application of Li-S batteries in the near future.

Lithium–sulfur (Li–S) battery represents a high‐performance energy storage technology that will find applications in diverse areas, such as stationary and portable electronics as well as electric vehicles. Yet, dissolution of lithium polysulfides from cathode into organic electrolytes and the subsequent diffusion toward anode are two primary challenges that compromise the battery performance and hamper its wide‐spread commercialization. Deliberate manipulation of the sulfur cathode by physical confinement, covalent formation of polymeric sulfur, and incorporation of chemically binding materials has been extensively reported in the literature for improving the corresponding cycling stability and other key electrochemical properties. In this article, we summarize recent key progress in structural engineering of cathode materials in the enhancement of the device performance and conclude with a perspective of the promises and challenges of Li–S battery technology.
