Abstract:
Layered materials have attracted considerable attention in recent years due to their diverse properties, including tunable bandgaps, valley polarization, and weak van der Waals interlayer forces, which enable a wide variety of promising applications. Among them, silicon disulfide (SiS 2 ) exhibits interesting chemical and physical properties. However, synthesizing SiS 2 remains difficult due to the high pressure and temperature requirements and the easy vaporization of the S source. Herein, we establish a simple large-scale synthesis of layered orthorhombic SiS 2 using a solid–gas phase reaction. Additionally, it is evaluated for its Li-storage properties as an anode material for Li-ion batteries (LIBs). The SiS 2 nanocomposite, which was fabricated using amorphous carbon in a simple mechanical process, has a high lithiation/delithiation capacity of 1610/1363 mA h g −1 , high initial coulombic efficiency of 84.7%, extremely high cycling stability after 800 cycles, and high rate capability. Furthermore, SiS 2 is incorporated into a Li-argyrodite solid-state electrolyte (Li 6 PS 5 Cl, SSE) used in all-solid-state batteries (ASSBs), resulting in commendable air/moisture stability and high ionic conductivity with low activation energy. Accordingly, the large-scale synthesis method, exceptionally high Li-storage characteristics, and remarkable SSE application of the layered SiS 2 make it highly suitable for a variety of applications.
