Single-walled carbon nanohorns with unique horn-shaped structures as a scaffold for lithium-sulfur batteries

A novel single-walled carbon nanohorn-sulfur composite with high sulfur content up to 76% was synthesized via a straightforward melt-infusion strategy. The composite exhibits excellent electrochemical performance with a high capacity of 693 mA h g(-1) retained after 100 cycles at a high rate of 1.6 A g(-1).
