Abstract

The consumption of fossil fuels as non-renewable energy sources has been rising, posing significant threats to both human life and the environment. Currently, the research focuses on addressing the high energy demands of modern society. Supercapacitors have garnered considerable attention drawn because of their exceptional features such as high power density, reliable long cycle stability, rapid charge/discharge capabilities, and environmentally friendly nature. Supercapacitor performance depends significantly on the large surface area of electrode materials and the characteristics of the electrolyte. Renowned for its outstanding potential as an electrode material, graphene is highlighted in this review, particularly when combined with TMOs such as Ru, Co, Ni, and Mn. This study explores TMOs with various nanocomposites emphasizing their roles in supercapacitor electrodes and detailing the charge/discharge mechanisms. It also highlights current trends and potential future research avenues to enhance the performance of next-generation supercapacitor devices.

期刊介绍： The objective of the Journal of Nanoparticle Research is to disseminate knowledge of the physical, chemical and biological phenomena and processes in structures that have at least one lengthscale ranging from molecular to approximately 100 nm (or submicron in some situations), and exhibit improved and novel properties that are a direct result of their small size. Nanoparticle research is a key component of nanoscience, nanoengineering and nanotechnology. The focus of the Journal is on the specific concepts, properties, phenomena, and processes related to particles, tubes, layers, macromolecules, clusters and other finite structures of the nanoscale size range. Synthesis, assembly, transport, reactivity, and stability of such structures are considered. Development of in-situ and ex-situ instrumentation for characterization of nanoparticles and their interfaces should be based on new principles for probing properties and phenomena not well understood at the nanometer scale. Modeling and simulation may include atom-based quantum mechanics; molecular dynamics; single-particle, multi-body and continuum based models; fractals; other methods suitable for modeling particle synthesis, assembling and interaction processes. Realization and application of systems, structures and devices with novel functions obtained via precursor nanoparticles is emphasized. Approaches may include gas-, liquid-, solid-, and vacuum-based processes, size reduction, chemical- and bio-self assembly. Contributions include utilization of nanoparticle systems for enhancing a phenomenon or process and particle assembling into hierarchical structures, as well as formulation and the administration of drugs. Synergistic approaches originating from different disciplines and technologies, and interaction between the research providers and users in this field, are encouraged.
