“…For example, Al 2 O 3 coating with a thickness of 14 μm was generated on a polyolefin separator and good barrier properties were demonstrated with the battery tests . Ex situ energy dispersive X‐ray spectroscopy (EDX) measurements showed that MnO could also adsorb S species and a separator coated with MnO component had good battery performance (Table entry 13) . Furthermore, MnO in the composite separator may contribute to the electrocatalytic reduction of S species, which further promotes its battery performance.…”

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.

“…77 The concept of chemisorption for various Mn-based materials began to surface as functional interlayer materials. [78][79][80] As seen in Figure 8A, the sandwiched vein-membrane structure provides an effective physical shield with reduced pore sizes to restrict the polysulfides. The functional MnO 2 /GO/CNT (G/M@CNT) interlayer can improve the polysulfide-trapping ability due to chemical interactions between polysulfides as well as oxygen groups in MnO 2 nanoparticles and GO sheets.…”

Sulfur cathode offers a high theoretical specific capacity of 1,675 mAh g À1 and a high specific energy of 2,600 Wh kg À1 when implemented in lithium-sulfur batteries (LSBs). Moreover, sulfur is the redundant by-product of the petroleum industry, ensuring the low cost of LSBs. These features make LSBs particularly competitive among next-generation energy storage systems. However, the sulfur cathode suffers from several challenges such as a large volume change, low electrical conductivity of sulfur, as well as the polysulfide shuttle effect, which result in low utilization and loss of cathode active materials. Insertion of membranes (or so-called interlayers) between the separator and cathode has been demonstrated as a promising approach to alleviate these issues. In this review, recent progress regarding the advanced interlayer systems are summarized. Specifically, we generalize the different types of interlayers, and the operating mechanisms and widespread availability of interlayers in LSBs are concluded. Furthermore, the scientific/technical challenges and perspective are presented.

“…Functional separators were also modified with metal oxides and their composites to improve the electrochemical performance of the Li–S batteries, such as Al 2 O 3 , V 2 O 5 , MnO/Ketjen Black, and Mg 0.6 Ni 0.4 O/Ketjen Black composite, because their strong polysulfide binding effects of oxygen‐rich metal oxides help to suppress the diffusion of polysulfides to the lithium anode side. To further address the shuttle effect of lithium polysulfides and the corrosion problem of Li anodes, multimodified separators have been prepared, including three‐layer separators of carbon nanotube/polypropylene/Al 2 O 3 , carbon/lithium aluminum germanium phosphate/Celgard, and sulfur/graphene/polypropylene .…”

Owing to their theoretical energy density of 2600 Wh kg , lithium-sulfur batteries represent a promising future energy storage device to power electric vehicles. However, the practical applications of lithium-sulfur batteries suffer from poor cycle life and low Coulombic efficiency, which is attributed, in part, to the polysulfide shuttle and Li dendrite formation. Suppressing Li dendrite growth, blocking the unfavorable reaction between soluble polysulfides and Li, and improving the safety of Li-S batteries have become very important for the development of high-performance lithium sulfur batteries. A comprehensive review of various strategies is presented for enhancing the stability of the anode of lithium sulfur batteries, including inserting an interlayer, modifying the separator and electrolytes, employing artificial protection layers, and alternative anodes to replace the Li metal anode.
