Abstract

Three-dimensional (3D) TiO2-SnO2-graphene aerogels (TTGs)were built up from the graphene oxide nanosheets supported with both TiO2 and SnO2 nanoparticles (NPs) via a facile hydrothermal assembly process. The resulting TTGs exhibit a 3D hierarchical porous architecture with uniform distribution of SnO2 and TiO2 NPs on the graphene surface, which not only effectively prevents the agglomeration of SnO2 NPs, but also facilitates the fast ion/electron transport in 3D pathways. As the anode materials in lithium ion batteries (LIBs), TTGs manifest a high reversible capacity of 750 mA h g-1 at 0.1 A g-1 for 100 cycles. Even at a high current density of 1 A g-1, a reversible capacity of 470mA h g-1 can still be achieved from the TTG based LIB anode over 150 cycles.
