摘要A carbon-sulfur hybrid with pomegranate-like core-shell structure, which demonstrates a high rate performance and relatively high cyclic stability, is obtained through carbonization of a carbon precursor in the presence of a sulfur precursor (FeS2) and a following oxidation of FeS2 to sulfur by HNO3. Such a structure effectively protects the sulfur and leaves enough buffer space after Fe3+ removal and, at the same time, has an interconnected conductive network. The capacity of the obtained hybrid is 450 mAhg(-1) under the current density of 5 C. This work provides a simple strategy to design and prepare various high-performance carbon-sulfur hybrids for lithium-sulfur batteries.
