| Abstract: | Na2S as a source of sulfur, H202 as an oxidant, at the high temperature with HNO3 processing of carbon nanotubes （CNTs）, we synthesis the carbon nanotubes/sulfur （H-CNTs/S） cathode materials successfully under hydrothermal environment. The sulfur loading of materials are 49 wt%. The first discharge capacity is 680 mAh·g-1 at 0.2 C and it keeps the rate up to 75 % after 50 cycles, also the composite materials have showed excellent perIbrmance of rate capability. |
