英文摘要	Ultrasmall sub-5 nm SnO2 nanocrystals/carbon composites, with the SnO2 loading as high as 87.3 wt%, are synthesized via a facile hydrothermal route, followed by calcination. The annealed SnO2/C composite shows a higher discharge capacity and superior rate performance, compared with the pristine SnO2/C sample. At the current density of 200 mA g(-1), it can deliver a high reversible capacity of 968 mAh g(-1). When the current density increases to 5000 mA g(-1), a high discharge capacity of 435 mAh g(-1) can still be obtained, much higher than the theoretical capacity of graphite. Our results indicate the potential suitability of synthesizing ultrasmall electrode nanocrystals with high electrochemical performance. (C) 2016 Elsevier B.V.
