“…Many strategic improvements have been recommended in light of this fact: (1) reducing the number of paths for diffusion while increasing the surface area of electrodes by the use of nanoarchitectures [65]; (2) improving electrode conductivity [66] and (3) minimizing the ionic species' diffusional activation energy and (4) constructing three-dimensional materials to speed up ionic diffusion in all directions [67]. Consequently, many materials, including carbon-based composites with sp 3 and sp 2 hybridizations, diverse allotropic forms (e.g., graphene, fullerenes, nanotubes, diamond, etc), and varied dimensions, have been widely investigated to meet extensive demand [68][69][70][71]. Most electrochemical capacitors (ECs) studied herein used organic binders such as polytetrafluoroethylene as coated or pressed electrode supports in conjunction with carbon-based materials.…”

Efficient energy storage strategies have become a major priority in the last few years. Transition metal sulphides are popularly known as attractive electrode materials or supercapacitors due to their high theoretical capacitance, excellent electrical conductivity, and favourable redox properties. Through compositional and structural engineering, some transition metal sulphides like Mn, V, Co, Fe, Cu, Ni, Mo, Zn, W, and Sn have shown substantial improvements in electrochemical performance. Composite engineering and morphological control are two of the key strategies employed to improve the TMS electrode’s electrochemical performance. Excellent electrochemical TMSs address the issues of slow kinetics, poor stability, and large volume expansions. This study reveal optimised TMSs potential to transform supercapacitor applications and provides viable approaches to conquer current hurdles to shape the forthcoming century’s high-performance and low-cost energy storage technology. The effects of composite engineering and morphological control on the ultimate electrochemical performance of the electrode materials are the primary focus of this investigation. Challenges to the further advancement of transition metal sulphide-based electrode materials are also explored in this article. Critical approaches to resolving significant issues in our current understanding of the kinetic and mechanistic perspectives of charge storage processes, i.e., slow kinetics, poor stability, and volume expansions, are also highlighted. Ultimately, future potentials, challenges, and possible solutions to tackle these problems are broadly discussed.
