Tin-based materials have been considered as promising anode materials for their high theoretical capacities in rechargeable lithium ion batteries. However, the large volume variation during repeated lithiation/delithiation processes, leads to aggregation and pulverization of active materials, which limits their practical application. Herein, a facile and effective strategy was designed to construct interconnected porous SnOx/N-doped carbon framework, using Sn(IV)-containing polypyrrole as sacrificial template/precursor followed by depositing carbonaceous species via ethanol steam reforming pro...
