FeS under wrinkled thin-layer carbon derived from ionic liquid as a high-performance sodium-ion battery anode material

FeS is a promising anode material with high theoretical capacity in sodium-ion batteries (SIBs). Unfortunately, the unstable structure and poor conductivity of FeS limit its commercial applications. Herein, FeS coated by wrinkled thin layers of carbon (FeS/C) is synthesized by using a simple pyrolys...
