In this study, a dual-shell hollow polyaniline/sulfur-core/polyaniline (hPANI/S/PANI) composite was prepared by successively depositing PANI, S, and PANI on the surface of a template silicon sphere. The electrochemical properties of this composite were evaluated using a lithium plate as an anode in lithium/sulfur cells. The hPANI/S/PANI composite showed a discharge capacity of 572.2mAhg−1 after 214...
Sulfur deposited on a hollow polyaniline sphere was prepared through in situ synthesis and used to investigate the electrochemical properties of lithium/sulfur cells. The fabricated hPANIs@S composite presented an excellent reversible capacity of 601.9 mAh g−1 after 100 cycles at 170 mA g−1. The capacity increased with the cycle increase, especially at high charge/discharge current. For example, the...
