The selection of suitable electrode material is a fundamental step in the development of metal-ion batteries with enhanced performance. Herein, we have explored the feasibility of two dimensional sheets of germanium and tin sulfides and tellurides as promising high-capacity and stable materials for energy storage. GeS, GeTe, SnS, and SnTe 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. GeS, GeTe, SnS, and SnTe nanosheets deliver a high areal capacity of 1.76 mAh cm-2 ,1.05 mAh cm-2 , 2.66 mAh cm-2 , 1.22 mAh cm-2 respectively as anodes in lithium-ion batteries (LIBs). Further analysis of these monochalcogenides in sodium-ion batteries (SIBs) and potassium-ion batteries (KIBs) suggest that layered monochalcogenides can be potential anodes in other metal ion batteries as well.
