Nanostructured MoS₂‐, SnS₂‐, and WS₂‐Based Anode Materials for High‐Performance Sodium‐Ion Batteries via Chemical Methods: A Review Article

Abstract

In the current age, electric‐driven products based on large‐scale stationary energy‐storage devices, sodium‐ion batteries (SIBs) are good promising candidates due to their comparable low cost, environment friendliness, high efficiency, and relatable huge abundance. An anode plays a vital role in the high performance of rechargeable batteries, so it becomes necessary to focus on the research on high‐performance anode materials. Recently, a number of researchers developed advanced host materials for SIBs to boost their energy density, cycle efficiency, and safety measures. In recent years, nanostructured metal sulfides like MoS2, SnS2, and WS2 with their novel structure‐based anode materials are the focus of the key research in sodium‐storage applications because of their comparable high conductivity, high capacity, good cycle life, and unmatched chemical and physical properties. In addition, these metal sulfides exhibit high mechanical, thermal, and structural stability, which supports them to find their place as an anode material for high‐performance SIBs in large‐scale energy storage production. Herein, the selected metal sulfide‐based nanostructures synthesized by chemical routes are extensively reviewed and their electrochemical properties for application as a high‐performance anode material in the SIBs are explored.

Stabilizing intermediate phases via the efficient confinement effects of the SnS2-SPAN fibre composite for ultra-stable half/full sodium/potassium-ion batteries

“…It is, therefore, a momentous breakthrough to design state-ofthe-art anode materials with simultaneous high energy density and long service life for SIBs and PIBs. [15][16][17][18][19] Considering the unique layered structure and high theoretical capacity of transition metal dichalcogenides (TMDs), [20][21][22] SnS 2 has garnered extensive interest due to its profoundly high theoretical capacity (1136 mA h g À1 ) and large interlayer distance (0.59 nm). This predominance makes SnS 2 stand out among anode materials for SIBs/PIBs.…”

Tuning kinetics of SnS/Ni3S4 binary sulfides for high rate and long cyclic lithium-ion batteries

“…41 There are several efforts on the development of SnS based binary systems such as SnS/MoS 2 , SnS/ZnS, CuS/SnS 2 , SnS-ZnS@C etc. [42][43][44][45][46][47] Although, tin and nickel based binary sulfides combined with supporting materials such as GO, rGO, carbon cloth, CNTs and Ni-foam have been extensively investigated for energy storage but pure tin and nickel based binary systems are scarcely explored. [48][49][50][51][52] In this paper, we report hierarchical flower-like novel SnS/Ni 3 S 4 binary sulfides with tuned morphology and chemical composition via a facile hydrothermal approach.…”

Cationic and anionic dual redox activity of MoS2 for electrochemical potassium storage

“…These advantages have made MoS2 one of the most studied anode materials of PIBs. [10,[13][14][15] A great deal of research attention has been directed towards enhancing the PIB performance of MoS2 by addressing issues such as poor electronic conductivity and structural instability.…”
