مستخلص: SnS 2 as an anode material for sodium ion batteries (SIBs) reveals poor battery performance due to huge volume change and poor electrical conductivity. To address these problems, reduced graphene oxide coated flower-like SnS 2 (SnS 2 @rGO) was successfully designed for SIBs by virtue of a facile hydrothermal approach. For SnS 2 @rGO, a high specific capacity of 649 mAh g −1 is obtained at 50 mAh g −1 . After 100 cycles, a discharge capacity of 509 mAh g −1 is maintained. It turns out that the resistance of SnS 2 @rGO remains stable while that of the bare one increases with the growth of cycle. The improved performance can be attributed to the graphene, which can suppress the agglomeration of SnS 2 nanoparticles, enhance the conductivity of SnS 2 , and increase its structural stability during cycling. This study is a potent testimony to the property of SnS 2 @rGO composite that it is a promising anode material ideal for high performance SIBs. [ABSTRACT FROM AUTHOR]
