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

Abstract

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.
