Lithium–sulfur batteries are promising technologies for powering flexible devices due to their high energy density, low cost and environmental friendliness, when the insulating nature, shuttle effect and volume expansion of sulfur electrodes are well addressed. Here, we report a strategy of using foldable interpenetrated metal-organic frameworks/carbon nanotubes thin film for binder-free advanced lithium–sulfur batteries through a facile confinement conversion. The carbon nanotubes interpenetrate through the metal-organic frameworks crystal and interweave the electrode into a stratified structure to provide both conductivity and structural integrity, while the highly porous metal-organic frameworks endow the electrode with strong sulfur confinement to achieve good cyclability. These hierarchical porous interpenetrated three-dimensional conductive networks with well confined S8 lead to high sulfur loading and utilization, as well as high volumetric energy density.

“…Apart from the cathode architectures mentioned above, fabricating free-standing sandwich-structured cathodes is another option for the design of high-performance electrodes [43, [182][183][184][185][186][187]. The top and bottom layers act as current collectors as well as physical barriers to prevent polysulfide dissolution, and the middle section contains sulfur-based active materials.…”

“…Peng et al fabricated a laminated hybrid cathode by cross-stacking aligned CNT sheets and CMK-3/S composite particles layer by layer. Benefiting from excellent electron transport along the aligned CNT sheets and polysulfide confinement by CMK-3, the electrodes with a sulfur loading of up to 20 mg cm −2 showed a stable discharge capacity of 900 mA h g −1 for 50 cycles [182]. Chemical interactions via introducing polar groups or materials are another promising strategy.…”

Lithium-sulfur (Li-S) batteries have been considered as one of the most promising energy storage devices that have the potential to deliver energy densities that supersede that of state-of-the-art lithium ion batteries. Due to their high theoretical energy density and cost-effectiveness, Li-S batteries have received great attention and have made great progress in the last few years. However, the insurmountable gap between fundamental research and practical application is still a major stumbling block that has hindered the commercialization of Li-S batteries. This review provides insight from an engineering point of view to discuss the reasonable structural design and parameters for the application of Li-S batteries. Firstly, a systematic analysis of various parameters (sulfur loading, electrolyte/sulfur (E/S) ratio, discharge capacity, discharge voltage, Li excess percentage, sulfur content, etc.) that influence the gravimetric energy density, volumetric energy density and cost is investigated. Through comparing and analyzing the statistical information collected from recent Li-S publications to find the shortcomings of Li-S technology, we supply potential strategies aimed at addressing the major issues that are still needed to be overcome. Finally, potential future directions and prospects in the engineering of Li-S batteries are discussed.

“…Therefore, optimal conductive carbon substrates should be combined with functional carbon materials possessing porous structures or functional groups to enhance sulfur loadings and act as trapping sites for polysulfides. For example, Sun et al [163] prepared carbon hybrid cathodes based on mesoporous carbon CMK-3 and CNTs and reported high electrochemical performances. Here, mesoporous carbon can provide void spaces to accommodate sulfur and its porous structure can inhibit the diffusion of polysulfide intermediates.…”

Compared with conventional lithium ion batteries (LIBs), lithium sulfur (Li-S) batteries possess advantages such as higher theoretical energy densities and better cost efficiencies, making them promising next-generation energy storage systems. However, the commercialization of Li-S batteries is impeded by several drawbacks, including low cycling stabilities, limited sulfur utilizations, existing shuttle effects of polysulfide intermediates, serious safety concerns, as well as inferior cycling performances of lithium metal anodes. To address these issues, researchers have achieved rapid developments for sulfur cathodes and increased their attention to lithium metal anodes to facilitate the widespread application of Li-S batteries. And among the substrate materials for electrodes in Li-S batteries being developed, carbon-based materials have been especially promising because of their multifunctionality, demonstrating great potential for application in advanced energy storage and conversion systems. In this review, recent advancements of carbon-based frameworks applied to Li-S batteries will be summarized and diverse utilization methods of these carbon-based materials for both sulfur cathodes and lithium metal anodes will be provided. Future research directions and the prospects of Li-S batteries with high performance and practicability will also be discussed. Keywords
