Abstract
Polyaniline coated mesoporous carbon/sulfur composite (CMK3/S-PANI) was prepared by an in-situ polymerization of aniline monomer on the surface of CMK3/S composite. The CMK3/S-PANI composite exhibits much better electrochemical performance than the uncoated CMK3/S composite and delivers initial discharge capacity of 1103 mAh g- 1 and maintains 649 mAh g- 1 after 100 cycles at 1C rate. The coating layer can suppress the diffusion of discharge intermediate product into electrolyte and improve the cycling performance of the composite cathode.
