Abstract
Heterostructured Fe2O3/Fe7S8 hollow fibers were rationally designed and synthesized via the electrospinning technique, followed by a calcination process and sulfuration treatment. Benefitting from the synergistic effect of the hollow structure and the built-in electric field induced by the heterostructure, the as-prepared Fe2O3/Fe7S8 composite anode exhibits high specific capacity (947 mA h g−1 after 100 cycles at 0.2 A g−1), excellent rate capability, and long-term cycling stability (730 mA h g−1 after 1000 cycles at 1 A g−1).
