“…It is noted that the LiPSs anchoring behaviors on the F‐terminated and O‐terminated Ti 2 C are different . While the former can effectively suppress the shuttle effect because of stronger binding energy ( E b ) of LiPSs intermediates, the latter prefers to convert the long‐chain LiPSs into insoluble elemental S, thus retards the shuttle effect . In other words, the interaction between the functionalized surface (‐F or ‐O) and LiPSs should be emphasized in realizing high‐capacity, long‐lifetime Li‐S batteries (Figure b) …”

A family of 2D transition metal carbides and nitrides known as MXenes has received increasing attention since the discovery of Ti3C2 in 2011. To date, about 30 different MXenes with well‐defined structures and properties have been synthesized, and many more are theoretically predicted to exist. Due to the numerous assets including excellent mechanical properties, metallic conductivity, unique in‐plane anisotropic structure, tunable band gap, and so on, MXenes rapidly positioned themselves at the forefront of the 2D materials world and have found numerous promising applications. Particular interest is devoted to applications in electrochemical energy storage, whereby 2D MXenes work either as electrodes, additives, separators, or hosts. This review summarizes recent advances in the synthesis, fundamental properties and composites of MXene and highlights the state‐of‐the‐art electrochemical performance of MXene‐based electrodes/devices. The progresses in the field of supercapacitors and Li‐ion batteries, Li‐S batteries, Na‐ and other alkali metal ion batteries are reviewed, and current challenges and new opportunities for MXenes in this surging energy storage field are presented. In the focus of interest is the possibility to boost device‐level performance, particularly that of rechargeable batteries, which are of utmost importance in future energy technologies. Very recently, the 2019 Nobel Prize in Chemistry was awarded to the inventors of the Li‐ion battery. For sure, this will provide an additional stimulation to study fundamental aspects of electrochemical energy storage.

“…In fact, the as-obtained Ti 2 CT x MXene nanosheets have neither a high specific surface area nor a well-ordered porous architecture. [93,94] In addition, the redox reaction of polysulfides occurs on the surface of MXene due to the metallic conductivity of MXene after absorbing polysulfides. [26] Restacking MXene nanosheets limit the accessibility of active ions and impede the utilization of MXene surfaces.…”

“…However, owing to the existence of STiC bonding, Ti 2 CT x /S cathodes clearly show great performance, suggesting that the "shuttle effect" can be efficiently suppressed.

Tremendous efforts are devoted to developing advanced electrode materials with superior electrochemical performance, high energy density, and high power density for energy storage and conversion. Two‐dimensional (2D) materials, owing to their unique properties, have shown great potential for energy storage. Following the discovery of graphene, a new family of 2D transition metal carbides/nitrides, MXenes, derived from MAX phase precursors, have attracted extensive attention in recent years. The superior physical and chemical properties of MXenes include high mechanical strength, excellent electrical conductivity, multiple possible surface terminations, hydrophilic features, superior specific surface area, and the ability to accommodate intercalants. When applied as electrodes in lithium‐based batteries, MXenes have demonstrated excellent performance. In this progress report, the authors summarize the recent advances of MXenes and MXene‐based composites in terms of synthesis strategies, morphology engineering, physical/chemical properties, and their applications in lithium‐ion batteries and lithium–sulfur batteries. Furthermore, challenges and perspectives for MXenes and MXene‐based composites for lithium‐based energy storage devices are also outlined.

“…Metal carbide are an exciting family of transition-metal carbides, 37,150,151 which are inherently highly conductive and possess a highly active 2D surfaces to chemically bond to intermediate polysulphides by metal-sulphur interactions. 37 Nazar's group first reported a new class of sulfur host materials-conductive MXene Ti 2 C. 37 The MXene Ti 2 C, not only displays the characteristic high 2D electron conductivity of transition-metal carbides (much higher than GO), but also its exposed terminal metal sites can bind to the sulphides as revealed by X-ray photoelectron spectroscopy (XPS) analysis, with the corresponding mechanism scheme shown in Fig.…”

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.
