A multi-core–shell structured composite cathode material with a conductive polymer network for Li–S batteries†
Abstract
A multi-core–shell with a conductive network structured C-PANI–S@PANI composite with high sulfur content up to 87% was synthesized. The composite cathode delivers higher specific capacity and excellent cycle stability, retaining a reversible discharge capacity of 835 mA h g−1 after 100 cycles when the sulfur loading of the cathode was above 6 mg cm−2.
