title: FeV2S4 as a high capacity electrode material for sodium-ion batteries.
abstract: Iron vanadium sulfide (FeV2S4) was synthesized via a high temperature solid state reaction and was investigated as a cheap anode material for Na and Li ion batteries. Discharge capacities as high as 723 mA h g(-1) (Na) and 890 mA h g(-1) (Li) were found for half-cell measurements at room temperature. The capacity of the Na-FeV2S4 system remained constant at 529 mA h g(-1) after the 10th cycle with an area capacity of 2.7 mA h cm(-2) being very close to that of conventional Li-ion technology.
