Lithium sulfur batteries attract the increasing attentions because of the high energy density. However, sulfur cathodes suffer from several scientific and technical issues which are related to polysulfide ion migration, low conductivity, and volume changes. Many strategies such as porous hosts, polysulfide adsorbents, catalyst, and conductive fillers and so on have been proposed to address these issues, separately. In this study, novel Co3S4 nanotubes are developed to efficiently host sulfur, adsorb polysulfide, and catalyze their conversion. Because of these multifunctional advantages in one structure, the resulting Co3S4@S nanotube electrodes demonstrate superior electrochemical properties for high performance lithium sulfur batteries.
