Lithium-sulfur (Li-S) batteries have been recognized as potential candidates for next-generation rechargeable cells because of their high energy density. However, polysulfides’ ‘shuttle effect’ and sluggish redox kinetics at cathode induced low sulfur utilization, severe capacity decay and short cyc...
