摘要：

We investigated the effects of multi-walled carbon nanotubes (MWNT) and graphitic nanofibers (GNF) on the performance of sulfur electrode for the lithium/sulfur battery. MWNT and GNF were manufactured by a thermal chemical vapor deposition (CVD) method, and then they were added as an additive in the sulfur electrode. The added sulfur electrodes were composed of 60wt% elemental sulfur (Aldrich), 20wt% acetylene black, 5wt% MWNT or GNF, and 15wt% poly ethylene oxide (PEO) dissolved in acetonitrile. No-added sulfur electrodes were prepared by mixing 60wt% elemental sulfur, 25wt% acetylene black, and 15wt% PEO. The addition of MWNT and GNF was found to give good electrochemical effects in sulfur electrode.
