Abstract
Abstract3D hierarchical tin oxide/graphene frameworks (SnO2/GFs) were built up by the in situ synthesis of 2D SnO2/graphene nanosheets followed by hydrothermal assembly. These SnO2/GFs exhibited a 3D hierarchical porous architecture with mesopores (≈3 nm), macropores (3–6 μm), and a large surface area (244 m2 g−1), which not only effectively prevented the agglomeration of SnO2 nanoparticles, but also facilitated fast ion and electron transport in 3D pathways. As a consequence, the SnO2/GFs exhibited a high capacity of 830 mAh g−1 for up to 70 charge–discharge cycles at 100 mA g−1. Even at a high current density of 500 mA g−1, a reversible capacity of 621 mAh g−1 could be maintained for SnO2/GFs with excellent cycling stability. Such performance is superior to that of previously reported SnO2/graphene and other SnO2/carbon composites with similar weight contents of SnO2.
