The solid Lewis acid HNb 3 O 8 (HNO) and oxygen‐vacancy‐rich HNO‐v have been investigated for Li‐S batteries. As Y. Du, B. Huang et al. show in their Research Article on page 11491 ff., the inferior performance induced by the oxygen vacancy is mainly attributed to the decreased electric conductivity and the weakened adsorption of polysulfide on the catalyst surface.
