The excellent barrier property of the composite separator was directly visualized with adiffusion model. SEM observations of the Li anode after cycling demonstrated the effective prevention of polysulfide diffusion.…”

Li-ion and Li-S batteries find enormous applications in different fields, such as electric vehicles and portable electronics. A separator is an indispensable part of the battery design, which functions as a physical barrier for the electrode as well as an electrolyte reservoir for ionic transport. The properties of the separators directly influence the performance of the batteries. Traditional polyolefin separators showed low thermal stability, poor wettability toward the electrolyte, and inadequate barrier properties to polysulfides. To improve the performance and durability of Li-ion and Li-S batteries, development of advanced separators is required. In this review, we summarize recent progress on the fabrication and application of novel separators, including the functionalized polyolefin separator, polymeric separator, and ceramic separator, for Li-ion and Li-S batteries. The characteristics, advantages, and limitations of these separators are discussed. A brief outlook for the future directions of the research in the separators is also provided.

“…Meanwhile, the utilization of BMCs to modify Li–S batteries is also in line with the requirements of environmental protection and sustainable development. Until now, there have been many types of BMCs used in the modification of Li–S batteries, such as BMCs derived from bamboo, eggshell, crab shell, lotus plumule, sweet potato, oak tree fruit shell, etc. At present, the cathodes of Li–S cells which are in the laboratory research mostly adopt carbon nanotubes, carbon nanofibers, and graphene materials with a novel structure and an excellent performance .…”

Lithium–sulfur batteries are recognized as novel energy storage systems because of their high theoretical specific capacity and energy density. Nevertheless, they also have technical bottlenecks such as the “shuttle effect”, poor conductivity of sulfur, and volume change. Herein, an effective porous activated carbon derived from puffed corn is coated on a polypropylene (PP) separator to improve the properties of lithium–sulfur batteries. Puffed corn carbon (PCC) and activated puffed corn carbon (APCC) are prepared by carbonization without and with KOH activation. Combined utilization of Fourier transform‐infrared spectroscopy (FTIR), X‐ray powder diffraction (XRD), Raman, N2 adsorption/desorption isotherm, and scanning electron microscopy (SEM) technologies demonstrates that the APCC sample has an amorphous carbon structure and it has high specific surface area of 2543.8 m2 g−1 and a large pore volume of 2.14 cm3 g−1. The cell with an APCC‐coated separator exhibit an initial discharge capacity of 1045 mAh g−1 at 1 C, and convert to 471.6 mAh g−1 after 500 cycles. Overall, APCC provides an extensive prospect for high‐performance lithium–sulfur batteries.

“…Along with Nafion, abundant materials could be put into use, which can be classified into three categories including carbon-based (Super P, [109][110][111] CNTs, [112] CNFs, [113] graphene, [114,115] porous carbon [116,117] ), functional groups (-COOH, [118] -SO 3 [119] ), and inorganic substance (MOF, [120] Al 2 O 3 , [121][122][123][124] V 2 O 5 , [124,125] NbC, [126] Li 4 Ti 5 O 12 [127] nanoparticles, and so on). All of them could selectively sieve Li + and efficiently alleviate the shuttle effect of polysulfides via physical adsorption.…”

Inspired by high theoretical energy density (~2600 W h kg−1) and cost‐effectiveness of sulfur cathode, lithium–sulfur batteries are receiving great attention and considered as one of the most promising next‐generation high‐energy‐density batteries. However, over the past decades, the energy density and reliable safety levels as well as the commercial progress of lithium–sulfur batteries are still far from satisfactory due to the disconnection and huge gap between fundamental research and practical application. Therefore, it is highly necessary to revisit the scientific issues for the industrial applications of lithium–sulfur batteries. In this review, we focus on discussing the impact of design parameters (such as compaction density, sulfur loading, and electrolyte/sulfur ratio) on the electrochemical performance of lithium–sulfur batteries and corresponding inherent relationship and rules between them. We also propose the practical design rules of advanced sulfur electrodes. Moreover, safety hazard in respect of electrolyte, separator, and lithium metal anode is also illustrated in detail. With the target of paving the way for practical application of lithium–sulfur batteries, feasible solutions and strategies are brought up to address the aforementioned problems. Finally, we will discuss the current challenges and future research chance of lithium–sulfur batteries.
