2D materials are regarded as promising electrode materials for rechargeable batteries because of their advantages in providing ample active sites and improving electrochemical reaction kinetics. However, it remains a great challenge for 2D materials to fulfill all requirements for high-performance energy storage devices in terms of electronic conductivity, the number of accessible active sites, structural stability, and mass production capability. Recent advances in constructing 2D material-based heterostructures offer opportunities for utilizing synergistic effects between the individual blocks to achieve optimized properties and enhanced performance. In this perspective, the latest advances of 2D material-based heterostructures are summarized, with particular emphasis on their multifunctional roles in high-performance rechargeable batteries. Synthetic strategies, structural features in mixed dimensionalities, structure engineering strategies, and distinct functionalities of the 2D material-based heterostructures in various electrochemical applications are systematically introduced. Finally, challenges and perspectives are presented to highlight future opportunities for developing 2D material-based heterostructures for practical energy storage.
