Boosting Polysulfide Conversion in Lithium-Sulfur Batteries by Cobalt-Doped Vanadium Nitride Micro-Flowers

The shuttle effect of polysulfide (Li2Sn, 2〈n≤8) and the sluggish reaction kinetics seriously hinder the development of lithium-sulfur (Li-S) batteries. Regulating the electronic structure of subst...
