Tin-based anode materials with high capacity attract wide attention of researchers and become a strong competitor for the next generation of lithium-ion battery anode materials. However, the poor electrical conductivity and severe volume expansion retard the commercialization of tin-based anode materials. Here, SnO 2 -SnS 2 @C nanoparticles with heterostructure embedded in a carbon matrix of nitrogen-doped graphene (SnO 2 -SnS 2 @C/NG) is ingeniously designed in this work. The composite was synthesized by a two-step method. Firstly, the SnO 2 @C/rGO with a nano-layer structure was synthesized by hydrothermal method as the precursor, and then the SnO 2 -SnS 2 @C/NG composite was obtained by further vulcanizing the above precursor. It should be noted that a carbon matrix with nitrogen-doped graphene can inhibit the volume expansion of SnO 2 -SnS 2  nanoparticles and promote the transport of lithium ions during continuous cycling. Benefiting from the synergistic effect between nanoparticles and carbon matrix with nitrogen-doped graphene, the heterostructured SnO 2 -SnS 2 @C/NG further fundamentally confer improved structural stability and reaction kinetics for lithium storage. As expected, the SnO 2 -SnS 2 @C/NG composite exhibited high reversible capacity (1201.2 mA h g −1  at the current rate of 0.1 A g −1 ), superior rate capability and exceptional long-life stability (944.3 mAh g −1  after 950 cycles at the current rate of 1.0 A g −1 ). The results demonstrate that the SnO 2 -SnS 2 @C/NG composite is a highly competitive anode material for LIBs.
