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(-1), high rate capability and good cycling performance, as we expected.
