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

Abstract

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.
