Electrochemical Decalcification-Exfoliation of Two-Dimensional Siligene, Si_xGe_y: Material Characterization and Perspectives for Lithium-Ion Storage.

ABSTRACT: A two-dimensional (2D) silicene-germanene alloy, siligene (Si_xGe_y), a single-phase material, has attracted increased attention due to its two-elemental low-buckled composition and unique physics and chemistry. This 2D material has the potential to address the challenges caused by low electrical conductivity and the environmental instability of corresponding monolayers. Yet, the siligene structure was studied in theory, demonstrating the material's great electrochemical potential for energy storage applications. The synthesis of free-standing siligene remains challenging and therefore hinders the research and its application. Herein we demonstrate nonaqueous electrochemical exfoliation of a few-layer siligene from a Ca_1.0Si_1.0Ge
