“…Conductive polymers are excellent additions for electrode improvement because of their many benefits, including high conductivity, environmental stability, and ease of synthesis. [ 130,135 ] For example, Zhang's group chose to build V 3 S 4 /PPy nanocomposites using polypyrrole (PPy), a common conductive polymer, as a supporting substrate. Notably, high conductivity of ppy makes it possible for it to both disperse around nanostructures similar to V 3 S 4 and act as a supporting substrate for them, which in turn improves ion transfer and energy storage conductivity.…”

Considering environmental changes and the demand for more sustainable energy sources, stricter requirements have been placed on electrode materials for sodium and potassium‐ion batteries, which are expected to provide higher energy and power density while being affordable and sustainable. Vanadium sulfide‐based materials have emerged as intriguing contenders for the next generation of anode materials due to their high theoretical capacity, abundant reserves, and cost‐effectiveness. Despite these advantages, challenges such as limited cycle life and restricted ion diffusion coefficients continue to impede their effective application in sodium and potassium‐ion batteries. To overcome the limitations associated with electrochemical performance and circumvent bottlenecks imposed by the inherent properties of materials at the bulk scale, this review comprehensively summarizes and analyzes the crystal structures, modification strategies, and energy storage processes of vanadium sulfide‐based electrode materials for sodium and potassium‐ion batteries. The objective is to guide the development of high‐performance vanadium‐based sulfide electrode materials with refined morphologies and/or structures, employing environmentally friendly and cost‐efficient methods. Finally, future perspectives and research suggestions for vanadium sulfide‐based materials are presented to propel practical applications forward.

“…In this context, it is anticipated that cobalt (Co) doping into VS 4 crystals with unique nanostructures will increase the oxidation states and reaction active sites of the electrode material, resulting in a significant enhancement of the electrochemical performance of SCs. 20 Nevertheless, Codoped VS 4 (Co-VS 4 ) frequently suffers from degradation in the KOH electrolyte during the continuous charge−discharge process, which results in poor cycling life of the electrode. 21 In addition, the electrochemical performance of Co-VS 4 is unstable because of its agglomeration.…”

Supercapacitors (SCs) have gained widespread recognition because of their advantageous power density as energy storage devices; it is still a great challenge to design a high-efficiency electrode material with outstanding energy density. In this work, nanorod-like cobalt-doped vanadium sulfide on a graphene nanosheet (Co-VS 4 /G) is successfully developed with a distinct nanostructure by employing a scalable solvothermal process. The morphology and structure of Co-VS 4 /G were explored to prove the Co doping well into the crystalline of VS 4 architecture. This creates more defects and brings about rich redox reactions, resulting in enhanced electrochemical performance. Noticeably, the fabricated Co-VS 4 /G composite exhibits a specific capacitance of 1230 F g −1 at 1 A g −1 with a rate capability of 796 F g −1 at a current density value of 30 A g −1 and cycling performance with 88.9% retention of its initial capacitance after 10,000 cycles. Furthermore, the as-fabricated Co-VS 4 /G//rGO asymmetric supercapacitor (ASC) device presents an energy density value of 75.8 W h kg −1 at a power density of 0.791 kW kg −1 and cycling stability with 91.1% of its capacitance following 10,000 cycles. The performance of the rodlike Co-VS 4 /G composite shows a predominant advantage toward the development of effective energy storage systems.
