Core-shell sulfur@polypyrrole composites as high-capacity materials for aqueous rechargeable batteries

Nanoscale. 2013 Feb 21;5(4):1460-4. doi: 10.1039/c2nr33590e.

Abstract

In order to explore the potential application of sulfur in aqueous rechargeable batteries, core-shell sulfur-polypyrrole (S@PPy) composites were prepared through a novel one-pot and surfactant-free method. Sulfur exhibits a very high capacity of 473 mA h g(-1) and good cycling stability in an aqueous Li(2)SO(4) electrolyte due to the polypyrrole coating.
