Abstract
Silicene , a two-dimensional (2D) allotrope of silicon with a hexagonal lattice structure akin to graphene, has emerged as a promising material for energy storage applications, particularly in batteries and supercapacitors . Its exceptional characteristics, including high theoretical capacity, large surface area, and mechanical flexibility, make it a key focus in the exploration of advanced materials . This review comprehensively examines recent advancements in the synthesis of silicene via bottom-up and top-down approaches, as well as alternative methods, highlighting its role in energy storage technologies. The discussion encompasses its applications in various battery systems, such as Li-ion, Na-ion, and K-ion batteries, along with supercapacitors , providing critical insights into both theoretical and experimental progress in the field. This review article aims to provide a thorough understanding of silicene's development and its transformative capabilities in advancing energy storage solutions.
