Abstract:

A three-dimensional SnO2 quantum dots/graphene aerogel (SnO2 QDs/GA) composite was prepared using a facile and scalable strategy without adding any surfactant and reducing agent. This as-prepared nanocomposite, with zero-dimensional SnO2 QDs (2-5 nm) anchoring and dispersing on the surface of three-dimensional graphene aerogel, exhibits better properties as anode material for sodium ion batteries than bare SnO2 for its higher reversible capacity (319 mAh g(-1) at 50 mA g(-1) after 50 cycles) and stability (rate capacity still remains 150 mAh g(-1) at 800 mA g(-1)). Such three-dimensional graphene aerogel could not only act as an electronic conductive matrix for the fast transportation of sodium ion and electrons, but also provide double protection against the aggregation and volume changes of SnO2 QDs during cycling.
