Understanding the lithium storage mechanism of free-standing Fe2N nanoparticles

Herein, we systemically studied the storage mechanism and effect of lithium ion (Li-ion) intercalation in Fe2N nanoparticles grown on carbon cloth using ex-situ characterizations including X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). The results confirm the conversion storage mechanism of the Fe2N as anode material for lithium ion batteries (LIBs). This study will provide valuable insights toward understanding Li-ion storage to other transition metal nitrides for LIBs.
