Abstract

The ultrafine Fe3O4nanoparticles (NPs) had a small size of 3 ∼ 5 nm and the HCNS had a thin shell thickness of 15 nm in the Fe3O4@HCNS. As a promising anode material for lithium-ion batteries, the Fe3O4@HCNS exhibited high reversible capacity, excellent cycling stability (1380 mA h g−1after 200 cycles at 1 A g−1) and high-rate capability (475 mA h g−1at 5 A g−1, 290 mA h g−1at 10 A g−1). The outstanding performance was attributed to the unique structure of the Fe3O4@HCNS, which greatly shorten the path of Li ions intercalation during charging and discharging.
