Silicene: A Promising Anode for Lithium‐Ion Batteries

Abstract Silicene, a single‐layer‐thick silicon nanosheet with a honeycomb structure, is successfully fabricated by the molecular‐beam‐epitaxy (MBE) deposition method on metallic substrates and by the solid‐state reaction method. Here, recent progress on the features of silicene that make it a prospective anode for lithium‐ion batteries (LIBs) are discussed, including its charge‐carrier mobility, chemical stability, and metal–silicene interactions. The electrochemical performance of silicene is reviewed in terms of both theoretical predictions and experimental measurements, and finally, its challenges and outlook are considered.
