Kinetically-enhanced polysulfide redox reactions by Nb2O5 nanocrystals for high-rate lithium-sulfur battery

To combat the shuttle of soluble polysulfides, physical confinement approaches aiming to trap sulfur within porous hosts have been pursued, but their success in terms of capacity decay and kinetic sluggishness is still limited. Herein, we update the confinement approach by integrating ultra-fine Nb2...
