Uniform F-doped Mn
3 O4 nanobelts have been synthesized by the molten salt method using NaF as the fluorine source and morphology stabilizer. The as-prepared materials are characterized by field emission scanning electron microscopy, transmission electron microscopy and X-ray photoelectron spectroscopy techniques. Based on the experimental results, a possible formation mechanism of the F-doped Mn3 O4 nanobelts is proposed. The electrochemical measurement indicates that the F-doped Mn3 O4 nanobelts exhibit a reversible electrochemical lithium storage capacity as high as 615 mA h g−1 at 100 mA g−1 after 100 cycles, and an excellent rate capability of 412 mA h g−1 at a high current density of 1000 mA g−1 .
