Large-scale synthesis of highly uniform Fe1−xS nanostructures as a high-rate anode for sodium ion batteries

An advanced Fe1−xS anode has been successfully prepared in large-scale by a simple one-step sulfurization route. A novel sodium ion full cell based on the Na0.6Co0.1Mn0.9O2 cathode and Fe1−xS anode, deliver high discharge capacity (393 mA h g−1) and superior cycling stability, making Fe1−xS nanostructures a competitive anode for NIBs.223
