“…Another interesting lithium-based energy storage device is the Li–S battery with a high theoretical capacity of 1672 mAh·g –1 using a sulfur electrode, which is an order of magnitude higher than those of the lithium-ion battery with transition-metal oxide cathodes. , The metallic TMDs have been explored as the host materials for sulfur (cathodes) in Li–S batteries. ,− For example, Li et al used lithiated metallic Li x MoS 2 as the sulfur host material for high-performance Li-S batteries . They restacked the exfoliated MoS 2 monolayer nanosheets (with lithium residues from the n -BuLi intercalation process) into Li x MoS 2 films (Figure d).…”

Two-dimensional (2D) transition metal dichalcogenides (TMDs) with layered crystal structures have been attracting enormous research interest for their atomic thickness, mechanical flexibility, and excellent electronic/optoelectronic properties for applications in diverse technological areas. Solution-processable 2D TMD inks are promising for large-scale production of functional thin films at an affordable cost, using highthroughput solution-based processing techniques such as printing and roll-to-roll fabrications. This paper provides a comprehensive review of the chemical synthesis of solution-processable and printable 2D TMD ink materials and the subsequent assembly into thin films for diverse applications. We start with the chemical principles and protocols of various synthesis methods for 2D TMD nanosheet crystals in the solution phase. The solution-based techniques for depositing ink materials into solid-state thin films are discussed. Then, we review the applications of these solution-processable thin films in diverse technological areas including electronics, optoelectronics, and others. To conclude, a summary of the key scientific/technical challenges and future research opportunities of solution-processable TMD inks is provided.

“…The transition metal compounds (TMCs) such as oxides (TMOs), sulfides (TMSs), nitrides (TMNs), phosphides (TMPs), and selenides (TMSes) have been developed as high polar hosts to immobilize LiPSs, accelerate the catalytic conversion, and induce homogeneous Li deposition. [13][14][15][16] Among them, TMN possesses a unique electronic structure and excellent physicochemical stability similar to that of noble metals, [17,18] such as Pt, Ru, and Ag, implying that this shows significant potential in its use in Li-S batteries. [19] However, the catalytic activity and lithophilic properties of TMN, subject to the contraction of the d-orbitals in the metal center, are far less excellent than those of noble metals.…”

The commercialization of lithium–sulfur (Li–S) battery is seriously hindered by the shuttle behavior of lithium (Li) polysulfide, slow conversion kinetics, and Li dendrite growth. Herein, a novel hierarchical p‐type iron nitride and n‐type vanadium nitride (p‐Fe2N/n‐VN) heterostructure with optimal electronic structure, confined in vesicle‐like N‐doped nanofibers (p‐Fe2N/n‐VN⊂PNCF), is meticulously constructed to work as “one stone two birds” dual‐functional hosts for both the sulfur cathode and Li anode. As demonstrated, the d‐band center of high‐spin Fe atom captures more electrons from V atom to realize more π* and moderate σ* bond electron filling and orbital occupation; thus, allowing moderate adsorption intensity for polysulfides and more effective d–p orbital hybridization to improve reaction kinetics. Meanwhile, this unique structure can dynamically balance the deposition and transport of Li on the anode; thereby, more effectively inhibiting Li dendrite growth and promoting the formation of a uniform solid electrolyte interface. The as‐assembled Li–S full batteries exhibit the conspicuous capacities and ultralong cycling lifespan over 2000 cycles at 5.0 C. Even at a higher S loading (20 mg cm−2) and lean electrolyte (2.5 µL mg−1), the full cells can still achieve an ultrahigh areal capacity of 16.1 mAh cm−2 after 500 cycles at 0.1 C.
