摘要：

In this paper, novel ternary Cu2SnS3 cabbage-like nanostructures are synthesized on a large scale via a facile solvothermal route. The individual Cu2SnS3 cabbage-like hierarchitecture is constructed from 2D nanosheets with thickness of about 15.6 nm. The Cu2SnS3 electrodes exhibit an initial reversible capacity of 842 mAh g(-1) and still reach 621 mAh g(-1) after 50 cycles. Such an admirable performance could be related to their 3D porous structural features as well as the high electrical conductivity induced by Cu. The electrochemical properties of the 3D hierarchical nanostructures imply its potential application in high energy density Li-ion batteries.
