The ZnSn(OH)6 nanocube-graphene composite as an anode material for Li-ion batteries.

ZnSn(OH)6 (ZSH) nanocubes with a uniform size of 40-80 nm were synthesized by using a simple hydrothermal route and then combined with graphene sheets (rGO) via the electrostatic interaction. The formed composite of ZnSn(OH)6 nanocube-graphene (ZSH-rGO) was used as an anode material for Li-ion batteries and it exhibited significantly enhanced electrochemical performance. For instance, a capacity of 540 mA h g(-1) at 500 mA g(-1) was retained after 40 cycles.
