摘要: Fe-based sulfides have received tremendous attention as promising anode materials for sodium ion batteries (SIBs) owing to their advantages of abundant resources, high theoretical specific capacity, and environmental benignity. However, unsatisfactory electronic conductivity and severe volume change during the cycling process limit their applications. Here, an FeS/N-doped carbon composite (FeS/NC) is designed and prepared through an in situ chemical transformation method via pyrolyzing a mixture of Fe (NO3) 3 …
