Anodes for lithium-ion batteries that are made of Sn-based materials are thought to be promising because they have a low operating voltage and a high theoretical capacity. Unfortunately, cycling causes a large expansion in volume, which quickly lowers capacity. We propose sulfur-doped porous carbon skeleton nanoparticles with SnO2 incorporated using a metal organic framework (MOF) technique (Sn@C-800). In addition to minimizing SnO2 particle aggregation and volume expansion, the enhanced stability of the carbon network prevents encapsulated SnO2 from coming into contact with the electrolyte. The inclusion of sulfur also increases the electrical conductivity of the material and provides sites for lithium-ion storage actives. The Sn@C-800 has a high-rate capacity of 1067 mAh g−1 of 0.1 A g−1 and a remarkable cycle performance of 1188 mAh g−1 at 1.0 A g−1. After 1000 cycles, the reversible capacity increases to 637 mAh g−1. This paper proposes a method for producing Sn-based LIBs anode materials with outstanding performance.
