摘要:	摘要： Exploitation of high‐performance anode materials is essential but challenging to the development of sodium‐ion batteries (SIBs). Among all proposed anode materials for SIBs, sulfides have been proved promising candidates due to their unique chemical and physical properties. In this work, a facile solvothermal method to in situ decorate cobalt sulfide (CoS) nanoplates on reduced graphene oxide (rGO) to build CoSrGO composite is described. When evaluated as anode for SIBs, an impressive high specific capacity (540 mAh g−1 at 1 A g−1), excellent rate capability (636 mAh g−1 at 0.1 A g−1 and 306 mAh g−1 at 10 A g−1), and extraordinarily cycle stability (420 mAh g−1 at 1 A g−1 after 1000 cycles) have been demonstrated by CoSrGO composite for sodium storage. The synergetic effect between the CoS nanoplates and rGO matrix contributes to the enhanced electrochemical performance of the hybrid composite. The results provide a facile approach to fabricate promising anode materials for high‐performance SIBs. A unique hybrid nanostructure based on transition metal sulfides and graphene (CoS/rGO) is developed through a facile solvothermal method. Benefiting from the synergetic effect between the CoS nanoplates and rGO matrix, the CoS/rGO composite demonstrates a high specific capacity, an excellent rate capability, and a good cycle performance as the anode material for sodium‐ion batteries. 其他題名： Small 出版者： Germany: Blackwell Publishing Ltd 出版日期： 2016-03-09 出處： Small (Weinheim an der Bergstrasse, Germany), 2016-03, Vol.12 (10), p.1359-1368 版權： 2016 WILEY‐VCH Verlag GmbH & Co.
