AI Article Synopsis
- A new type of 2D material, free-standing few-layer SnSb nanosheets, is created using a liquid-phase exfoliation method.
- The nanosheets are extremely thin (1-4 nm) with a high surface area and a precise ratio of tin (Sn) to antimony (Sb) at 1:1.
- When tested for lithium storage, these SnSb nanosheets show impressive performance with a reversible capacity of 694 mA h g, excellent rate capability, and good durability during cycling.
Article Abstract
A novel 2D alloy, free-standing few-layer SnSb nanosheets, is fabricated via a liquid-phase exfoliation approach. The resultant few-layer SnSb possesses ultrathin features (1-4 nm), large aspect ratio, largely exposed surfaces and a precise stoichiometric ratio between Sn and Sb (1 : 1). These few-layer SnSb nanosheets are systematically investigated for lithium storage, and exhibit a high reversible capacity of 694 mA h g, high rate capability and good cycling performance, as we expected.
