Cerium vanadate hollow spheres mediated polysulfide immobilization and conversion toward lithium-sulfur batteries
Abstract
Cerium vanadate (CeVO4) hollow spheres with abundant active sites and exceptional electrocatalytic activity effectively traps polysulfides and enhances the solid–liquid conversion kinetics. Accordingly, the designed CeVO4 as a multifunctional sulfur host boosts the lithium-sulfur batteries to deliver high reversible capacity and excellent cycling stability.
