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
