Two-dimensional materials in battery applications

초록

Two-dimensional (2D) materials have garnered significant attention due to their structural uniqueness, abundant electrochemically active sites, and favorable electrical and thermal properties. These attributes make them well suited to addressing intrinsic material- and mechanism-level limitations in advanced battery systems. Battery performance arises from a complex interplay of processes occurring across multiple components: anodes, cathodes, electrolytes, separators, and protective coatings. Here, we comprehensively examine how diverse 2D materials are integrated into each component, with an emphasis on the underlying mechanisms. While the discussion is anchored in well-established lithium-ion batteries, 2D-inspired strategies are also discussed in the context of emerging battery chemists. Overall, this review provides a consolidated overview of recent progress to clarify the roles of 2D materials across battery components.
