Abstract
Tin sulfides are promising anode materials for sodium-ion batteries (SIBs) for their high theoretical capacity and fast kinetics for Na storage. However, the severe volume expansion and intrinsically low charge conductivity fundamentally compromise their electrochemical performance. Addressing at the issue, SnS /SnS heterostructures are decorated on three-dimensional graphene nanosheets (3D GNS) framework, which is then shielded with a nanocarbon layer. In this nanocomposite, the SnS /SnS p-n heterostructures induce an internal electric field on the heterointerfaces to promote the charge transfer inside the material, which effectively ensures the rate capability of the material. Moreover, the 3D GNS provides a porous conductive network to accelerate the long-range transport of electron further enhancing its rate performance. Meanwhile, the dual-carbon structure would alleviate the volume expansion of SnS /SnS during cycling, ensuring improved stability. The integratio ....
