Abstract
With the continuous growth of global energy demand and the increasing severity of environmental issues, the development of efficient and environmentally friendly energy storage materials has become a research hotspot. This study focuses on the design and preparation of novel nanocomposite materials and explores their potential applications in the field of energy storage. By combining conductive polymers with two-dimensional transition me tal compounds, nanocomposites with high specific surface areas and excellent electrical conductivity were successfully fabricated using solvothermal methods and in-situ polymerization techniques. These materials exhibit unique microstructural characteristics, where their layered structures not only facilitate rapid ion transport but also effectively alleviate volume changes during charge-discharge processes. Electrochemical test results indicate that the prepared composites demonstrate superior specific capacity, cycling stability, and rate performance in lithium-ion batteries and supercapacitors. Compared with traditional single-component materials, this composite significantly enhances both energy density and power density, offering new insights into the development of high-performance energy storage devices. The innovation of this study lies in optimizing the synergistic effects between conductive polymers and two-dimensional materials, while proposing a scalable fabrication method. This achievement not only advances the application of nanocomposites in energy storage but also lays a theoretical foundation for the future design and modification of related materials.
