dc.description.abstract | Pyrite (FeS2) is an attractive anode material for sodium-ion batteries (SIBs) with a high theoretical capacity of 894 mAh g−1. However, its practical application is greatly hindered by the rapid capacity fading caused by the large volume expansion upon sodiation. Tuning the morphology and structure at nanoscale and applying a higher cut-off voltage are essential to address this issue. Here, a facile etching method coupled with a novel sulfidation-in-nanobox strategy is developed to synthesize unique FeS2@C yolk–shell nanoboxes. The as-obtained FeS2@C nanoboxes reveal excellent sodium storage performance. The remarkable electrochemical properties are attributed to the elaborate yolk–shell nanoarchitecture. In particular, it delivers a high specific capacity of 511 mAh g−1 at 100 mA g−1 after 100 cycles. Furthermore, a high specific capacity of 403 mAh g−1 even at 5 A g−1 is delivered. Most impressively, a stable capacity of 330 mAh g−1 can still be retained at 2 A g−1 even after 800 cycles. | - |
