Electrocatalysis of polysulfide conversion via sulfur–cobalt CoS2 on a carbon nanotube surface as a cathode for high-performance lithium–sulfur batteries

Lithium–sulfur batteries received intense attention because of their high-energy density and inexpensive active material. However, the poor electrical conductivity of sulfur, shuttle effect, and slow electrochemical kinetics hinder their application. Herein, cobalt disulfides uniformly in situ grow...
