Synergistic electrocatalysis of polysulfides by a nanostructured VS4-carbon nanofiber functional separator for high-performance lithium–sulfur batteries

The sluggish redox kinetic and the severe shuttle effect remain the key issues for the application of lithium–sulfur batteries, resulting in low sulfur utilization and rapid capacity fading. Herein, a nanostructured VS4 anchored on defect-rich carbon nanofibers (CNF-VS4) was coated on the commercial...
