Surface modification with metallic NPs on the materials used as supercapacitor electrodes

Original language description

The modification of electrode materials with metallic nanoparticles (NPs) has emerged as a pivotal strategy for enhancing the performance of supercapacitors. This work is concerned with the incorporation of metallic nanoparticles (NPs) into carbon-based materials and transition metal oxides, to elucidate the synergistic effects that serve to enhance the electrochemical properties of these electrodes. Carbon materials, including activated carbon, carbon nanotubes, and graphene, exhibit high surface area and excellent electrical conductivity. The introduction of metallic NPs, such as silver, copper, and platinum, further enhances these properties. The addition of these nanoparticles serves to increase the active surface area, reduce equivalent series resistance, and provide additional pseudocapacitance. Similarly, transition metal oxides such as Co₃O₄ and Mn₃O₄, which are known for their high theoretical capacitance, benefit from the incorporation of metallic nanoparticles through improved electrical conductivity and enhanced electrochemical stability. The underlying mechanisms of these enhancements are discussed, including improved electron transfer kinetics, increased active sites for charge storage, and better utilization of the electrode material. Furthermore, the work addresses the challenges in achieving uniform NP distribution, preventing NP agglomeration, and ensuring the long-term stability of the modified electrodes. Overall, the surface modification of electrode materials with metallic nanoparticles presents a promising avenue for the development of high-performance supercapacitors, combining the advantages of high energy and power density with long cycle life.Acknowledgement:This work was financially supported by the Ministry of Education, Youth and Sports, Czech Republic (contract no. 8F21007), National Centre for Research and Development, Poland (Project number: V4-Japan/2/17/AtomDeC/2022) through the research project cooperation between the AtomDeC Consortium by funding received from the Visegrad group(V4)-Japan 2021 2nd Joint Call on “Advanced Materials”, and by the European Union under the REFRESH - Research Excellence For REgion Sustainability and High-tech Industries (project no.
