ADVANCED FUNCTIONAL MATERIALS FOR HIGH-PERFORMANCE SUSTAINABLE ENERGY STORAGE AND CONVERSION APPLICATIONS

Abstract

The rapid advancement of sustainable energy technologies has intensified the need for high-performance functional materials capable of improving energy storage and conversion efficiency. This study presents a comprehensive comparative evaluation of advanced functional materials, including graphene-based nanocomposites, MXene hybrid structures, MOF-derived carbon materials, perovskite functional films, and conductive polymer blends, for sustainable energy applications. A multi-criteria analytical framework was developed to assess material performance based on energy density, power density, electrical conductivity, thermal stability, electrochemical efficiency, sustainability index, and lifecycle cost-effectiveness. Experimental characterization and comparative analysis revealed that MXene hybrid structures exhibited superior overall performance, achieving the highest power density, conductivity, and operational stability, while MOF-derived carbon materials demonstrated exceptional energy storage capacity. Graphene-based composites showed strong multifunctional performance and sustainability characteristics. In contrast, perovskite films exhibited limitations in thermal stability and environmental compatibility. The study further integrates cost-performance optimization and sustainability assessment to identify the most suitable materials for next-generation renewable energy systems. The findings provide a robust scientific framework for material selection and optimization in advanced sustainable energy storage and conversion technologies, contributing significantly to future research and industrial applications.
