    Abstract:

    The sulfur-carbon composites made of sulfur and CNT (Carbon nanotube) bundles were synthesized by thermally treating the as-prepared CNT bundles with sublimed sulfur at 300 oC. A loading of 62 % sulfur is obtained after thermal treatment. The as-prepared cathode samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The sulfur-CNT bundles showed high capacity and good cycle performance. It is suggested that the sulfur-CNT bundle composite can effectively confine the diffusion of dissolved polysulfides in the organic electrolyte.
