Abstract

Herein, a bimetallic sulfide Fe_0.4Co_0.6S₂@NC nanobox was prepared via a simple two-step synthetic route. The N-doped carbon coated hollow nanobox was derived from a Prussian blue analogue (PBA) and applied for an SIB anode. As expected, it exhibits a high capacity (486.6 mA h g^-1 at 0.1 A g^-1) and displays an excellent cycling stability (230 mA h g^-1 at 10 A g^-1 after 900 cycles).
