摘要：

Polypyrrole (PPy) nanowire was synthesized through a surfactant mediated approach. The sulfur-polypyrrole (S-PPy) composite materials were prepared by heating the mixture of element sulfur and polypyrrole nanowire. The materials were characterized by FIR, SEM. PPy with special morphology serves as conductive additive, distribution agent and absorbing agents, which effectively enhanced the electrochemical performance of sulfur. The initial discharge capacity of the active materials was 1222 mA h g(-1) the remaining capacity is 570 mA h g(-1) after 20th cycles. (C) 2008 Elsevier B.V. All rights reserved.
