Because of their high energy densities and specific capacities, lithium–sulfur (Li–S) batteries have recently received an extensive amount of research. The best way to boost battery performance is by altering the electrode materials. The adoption of 2D material-based heterostructures has attracted significant attention for increasing electrochemical performance and preventing the shuttle effect. Therefore, a summary of the link between the specific properties of 2D material heterostructures and electrochemical performance is required for the development of next-generation Li–S batteries. The present research focuses on the latest developments that boost the performance of Li–S batteries by using the unique features of 2D material heterostructures. This evaluation also categorizes several meticulously selected 2D materials with specific properties. Some solutions have been developed to overcome the difficulties of insulating intermediates, polysulfide shuttle, and sluggish kinetics. Superior conductivity, tunable functional groups, and exceptional flexibility are some of the most crucial elements in boosting electrochemical performance.

“…[ 50 ] In addition, Alsharaeh and co‐workers synthesized two kinds of BN‐based sulfur hosts, including RGO/BN composites and Co 3 O 4 /CoO/GNS/h‐BN (GNS is graphene nanosheets)catalyst. [ 51 ] These composite hosts delivered good electrochemical performances at higher temperature of 100 °C, which could be attributed to the introduction of highly conductive graphene nanosheets and catalytic activity of Co 3 O 4 ‐based catalysts. The integration of graphene with BN not only facilitates the formation of CoO in composites, but shows synergistic effects on the adsorption of LiPSs.…”

At the technological forefront of energy storage, there is still a continuous upsurge in demand for high energy and power density batteries that can operate at a wide range of temperature. Rechargeable lithium sulfur batteries stand out among other advanced cell concepts owing to their ultrahigh theoretical gravimetric energy density characteristic as well as merits of low cost and environmental friendliness. Although achieving good operability of ambient lithium sulfur batteries, extending their workability to both higher and lower temperatures is also of paramount importance especially for future task-specific applications. As a first attempt, this review presents a comprehensive understanding on the advances, challenges, and future research directions on lithium sulfur batteries operating at both low and high temperature extremes. From a material perspective, the workability of sulfur-containing cathode materials, advanced electrolytes (from conventional liquid to quasi-and all-solid-state electrolytes), lithium metal anodes and the electrochemically inert components (separators and interlayer materials) at extreme temperatures are thoroughly analyzed. The insurmountable challenges and mechanistic understandings caused by thermal changes are critically reviewed. Finally, potential future research directions and prospects for lithium sulfur batteries operated at a wide range of temperature are also proposed.

“…In this aspect, confining the sulfur and lithium polysulfides into controllably synthesized optimal matrix materials has been demonstrated to be an effective route to support sulfur and trap LiPSs. [20][21][22][23][24][25] Some carbonaceous composites, including carbon nanosheets, [26][27][28] carbon nanotubes, [29][30][31] carbon spheres [32][33][34] and graphenebased composites, [35,36] were generally chosen as sulfur hosts. The porous carbon hosts can enhance the conductivity of sulfur cathode as well as retain polysulfides within the porous structures.…”

Lithium‐sulfur (Li−S) batteries have become a research focus for high‐energy‐density rechargeable batteries owing to the considerable theoretical energy density. However, the polysulfide shuttle and sluggish kinetics in lithium‐sulfur (Li−S) chemistry lead to low sulfur utilization, large polarization and rapid capacity decay, posing a fatal threat to the commercialization of Li−S batteries. Herein, we etched zeolitic imidazolate framework‐67 (ZIF‐67) with Ni2+ to manufacture NiCo‐LDH, which is used as a sulfur host material for lithium‐sulfur (Li−S) batteries. Benefited from the closely packed nano‐clusters and the hollow structure, the NiCo‐LDH could not only inhibit the lithium polysulfides (LiPSs) diffusion but also accelerate the redox reactions. Owing to these properties, the corresponding Li−S batteries exhibit a superior capacity (1540 mAh g−1 at 0.1 C) and high rate performance (485 mAh g−1 at 5.0 C). This work shows a promising way for layered double hydroxide as cathodes for Li−S batteries.
