Recent development of polysulfide barriers for Li-S batteries

  • Li-S batteries have attracted great attention for their high theoretical specific capacity (1 675 mAh·g-1) and energy density (2 600 Wh·Kg-1). However, their low conductivity and poor utilization efficiency of sulfur greatly restrict practical applications. Novel polysulfide barriers have been designed and fabricated to overcome the shuttle effect and to improve cycle stability. In this review, the recent development of polysulfide barrier materials for Li-S batteries is introduced, which include carbon materials, metal oxides and conducting polymers. The development of an integrated electrode consisting of a polysulfide barrier and separator could be a hot research topic for Li-S batteries.
