摘要：

The rice grain-like FeS2/C nanomaterial with core-shell structure was prepared by anion displacement reaction. The prepared composite shows enhanced inoic and electronic conductivity, excellent electrolyte infiltration characteristics, and capability of buffering the volume change. When evaluated as anode of lithium ion batteries, the FeS2/C electrodes exhibit high reversible capacity of 1100 mA•h•g-1 at 100 mA•g-1 and outstanding rate capability. Even at high current density of 2 A•g-1, a reversible capacity of 866 mA•h•g-1 can be achieved. The results in this paper provide new ideas and methods for the preparation of other core-shell materials. © 2021, Editorial Board of CIESC Journal. All right reserved.
