One-step synthesis of an urchin-like sulfur/polyaniline nano-composite as a promising cathode material for high-capacity rechargeable lithium–sulfur batteries

Abstract

An urchin-like sulfur/polyaniline (S/PANI) nano-composite has been synthesized by a very soft and facile approach. This novel composite could be directly utilized as the cathode material for lithium–sulfur (Li–S) batteries and displays high specific capacity at different discharge current densities and good stability over long-term cycling.
