▎ 摘  要

ZnSnO3 hollow cubes@reduced graphene oxide aerogels (ZGAs) were fabricated via a colloid electrostatic self-assembly method between the graphene oxide (GO) nanosheets and poly(diallyldimethylammonium chloride) (PDDA) modified ZnSnO3 hollow cubes colloid, followed by hydrothermal and freeze-drying treatments. The unique porous architecture of ZnSnO3 hollow cubes encapsulated by flexible reduced graphene oxide (rGO) sheets not only effectively retarded the huge volume expansion during repeated charge -discharge cycles, but also facilitated fast lithium ion and electron transport through 3D networks. The ZGAs exhibited significantly enhanced cycling stability (745.4 mAh g (1) after 100 cycles at a current of 100 mAg (1)) and superior rate capability (as high as 552.6 mAh g 1 at 1200 mAg 1). The results indicate that the ZGAs are promising anode materials for high-performance lithium-ion batteries. (C) 2016 Elsevier Ltd. All rights reserved.
