Energy storage has become increasingly important as a study area in recent decades. A growing number of academics are focusing their attention on developing and researching innovative materials for use in energy storage systems to promote sustainable development goals. This is due to the finite supply of traditional energy sources, such as oil, coal, and natural gas, and escalating regional tensions. Because of these issues, sustainable renewable energy sources have been touted as an alternative to nonrenewable fuels. Deployment of renewable energy sources requires efficient and reliable energy storage devices due to their intermittent nature. High-performance electrochemical energy storage technologies with high power and energy densities are heralded to be the next-generation storage devices. Transition metal chalcogenides (TMCs) have sparked interest among electrode materials because of their intriguing electrochemical properties. Researchers have revealed a variety of modifications to improve their electrochemical performance in energy storage. However, a stronger link between the type of change and the resulting electrochemical performance is still desired. This review examines the synthesis of chalcogenides for electrochemical energy storage devices, their limitations, and the importance of the modification method, followed by a detailed discussion of several modification procedures and how they have helped to improve their electrochemical performance. We also discussed chalcogenides and their composites in batteries and supercapacitors applications. Furthermore, this review discusses the subject’s current challenges as well as potential future opportunities.

“…However, combining different nanostructures to form a hybrid nanoarchitecture provides unique properties, such as high porosity, large surface area, more active sites, high mass diffusion, and fast charge-transport process. 21,22 Biomass-derived activated carbon (AC)-based electrode materials are attracting increasing attention for negative electrode material in SC applications owing to their low cost, reduced toxicity, reproducibility, and abundance. [23][24][25] Biomass-derived ACs have been prepared using various sources such as mollusc shells, walnut shells, sugarcane, rice husks, coconut shells, and other biomass derivatives.…”

Recently, supercapacitors (SCs) are extensively explored as effective energy storage devices. Specifically, asymmetric SCs are being developed to enhance energy density using suitable materials with favorable nanostructures. This study describes the construction of a bismuth copper selenite (BCS‐200) working electrode with an ultrathin nanosheet (UTNS) architecture. This morphology is achieved using a low‐cost electrodeposition (ED) method, followed by annealing. The impact of ED time on the development of morphology is studied by synthesizing comparative electrodes simultaneously. The optimized BCS‐200 electrode prepared with a deposition time of 200 s shows higher specific capacity/capacitance (Cs/Csc) values of 330.9 mAh g−1/2206.6 F g−1 than the other synthesized electrodes (BCS‐100, BCS‐150, BCS‐250, and BCS‐300). Besides, a vapor‐grown carbon fiber (VGCF)‐added Fe2O3 composite coated on nickel foam (NF) is developed as a negative electrode. The VGCFs@Fe2O3/NF electrode exhibits the (Cs/Csc) values of 183.5 mAh g−1/734.4 F g−1, which is associated with ultra‐high cycling stability. In addition, the fabricated BCS‐200 and VGCFs@Fe2O3/NF electrodes are combined to construct a wearable semi‐solid‐state asymmetric SC (SSASC) with an energy density (Ed) of 20.5 Wh kg−1 and a cycling stability of 91.7% over 40000 charge/discharge cycles. Furthermore, the real‐time applicability of the SSASC is verified by powering it in practical applications.
