Vertical two-dimensional heterostructures and superlattices for lithium batteries and beyond

Abstract

Rechargeable batteries play an increasingly important role in the field of energy storage. To further improve battery performances, the controllable construction of heterostructures and superlattices based on existing promising materials is a very important strategy. Among different stacking structures, vertical two-dimensional (2D) heterostructures and superlattices have unique advantages and broad development prospects. This review sheds light on the significance and progress of vertical 2D heterostructures and superlattices for lithium batteries and beyond. It begins by introducing the advantages and classification of heterostructures and superlattices. Subsequently, it thoroughly examines the preparation and characterization methods of vertical 2D heterostructures and superlattices in a controlled manner. The discussion then shifts to the diverse applications of vertical 2D heterostructures and superlattices in various rechargeable batteries. Finally, the challenges and future developments of vertical 2D heterostructures and superlattices for rechargeable batteries are highlighted.
