Abstract
Two-dimensional van der Waals heterojunctions (2D vdWHs) have emerged as promising materials for next-generation flexible energy storage devices. Their unique physicochemical properties and interface engineering capabilities drive this potential. This comprehensive review systematically analyzes the recent developments in 2D vdWHs, focusing on their fundamental principles, fabrication methodologies, and applications in flexible energy storage systems. We first introduce the background of vdWHs and discuss four main synthesis strategies: direct stacking, chemical vapor deposition (CVD), in situ growth, and solution processing techniques. The review then extensively examines their applications in various flexible energy storage devices, including supercapacitors, lithium-ion batteries, zinc-ion batteries, and emerging storage systems such as potassium-ion, sodium-ion, and metal-air batteries. The review emphasizes the crucial role of heterojunction interfaces. These interfaces enhance electrochemical performance by improving charge transfer kinetics and maintaining structural stability. The superior performance of these materials is attributed to their large interfacial contact areas, synergistic effects between components, and optimized electron/ion transfer pathways. Despite significant progress, challenges remain in interface stability, scalable production, and performance optimization. We conclude by discussing future research directions, including novel materials development, advanced fabrication technologies, and emerging applications beyond energy storage. This review provides valuable insights for researchers working on next-generation flexible energy storage devices and highlights the transformative potential of 2D vdWHs in practical applications.
期刊介绍：
Advanced Composites and Hybrid Materials is a leading international journal that promotes interdisciplinary collaboration among materials scientists, engineers, chemists, biologists, and physicists working on composites, including nanocomposites. Our aim is to facilitate rapid scientific communication in this field.
The journal publishes high-quality research on various aspects of composite materials, including materials design, surface and interface science/engineering, manufacturing, structure control, property design, device fabrication, and other applications. We also welcome simulation and modeling studies that are relevant to composites. Additionally, papers focusing on the relationship between fillers and the matrix are of particular interest.
Our scope includes polymer, metal, and ceramic matrices, with a special emphasis on reviews and meta-analyses related to materials selection. We cover a wide range of topics, including transport properties, strategies for controlling interfaces and composition distribution, bottom-up assembly of nanocomposites, highly porous and high-density composites, electronic structure design, materials synergisms, and thermoelectric materials.
Advanced Composites and Hybrid Materials follows a rigorous single-blind peer-review process to ensure the quality and integrity of the published work.
