چکیده انگلیسی
Novel 3-D network SeSx/NCPAN (nitrogen-doped carbonized polyacrylonitrile) (x = 0.1 and 0) composites were prepared by one-step in situ solid-state method, directly heated the mixture of Se, S and PAN sealed in a quartz tube under vacuum, which was characterized by powder X-ray diffraction (XRD), energy-dispersive X-ray spectroscopy (EDS), thermogravimetric analysis (TGA), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Raman spectrum and X-ray photoelectron spectroscopy (XPS) techniques. It is discovered that SeS0.1 is dispersed in the 3-D network of NCPAN. The reversible electrode operation of SeS0.1 at ca. 1.1 V vs Li was identified with the capacity of 1387 mAh/g and around 600 mAh/g maintained after 20 cycles, demonstrating much better electrochemical performance than Se/NCPAN. This is the first study on one-step in-situ preparation of SeSx/NCPAN composites as the active cathode material for lithium-ion battery.
