Abstract
, HEO) hollow spheres were accurately designed and prepared as efficient catalysts to boost the polysulfide redox kinetics for lithium-sulfur batteries. Owing to the strong chemical adsorption and catalytic effect of HEO on polysulfide transformation, the HEO@S electrode exhibits excellent electrochemical performance.
