| Abstract Scope |
We present two-dimensional (2D) sheets of germanium sulfide (GeS) and germanium telluride (GeTe) as promising high-capacity and stable materials for energy storage. GeS and GeTe with layered structures are prepared via a simple liquid-phase exfoliation approach. As-synthesized 2D nanosheets can effectively increase the electrolyte-electrode interface area and facilitate metal ion transport. As a result, GeS and GeTe nanosheets deliver a high areal capacity of 1.76 mAh cm-2 and 1.05 mAh cm-2, respectively as anodes in lithium-ion batteries (LIBs). Further analysis of GeS and GeTe in sodium-ion batteries (SIBs) and potassium-ion batteries (KIBs) suggest that layered germanium monochalcogenides can be potential anodes in other metal-ion batteries. |
