文摘

Ferrous sulfide (FeS) particles dispersed in the pores of carbon (FeS/PC) from the polyacrylonitrile carbonization were prepared via a facile one-pot solid-state method, which was extensively characterized by XRD, SEM, TEM, Raman spectrum, and XPS techniques. As an anode material for lithium-ion batteries, this FeS/PC composite can achieve a high initial discharge capacity of 1428.8 mAh/g at 0.1 C, and can maintain 624.9 mAh/g capacity after 150 cycles. The porous carbon accommodates the volume change during the cycling, and the special structure of the FeS/PC composite results in its advanced electrochemical performance by enhancing the structure stability.
