Abstract

Abstract

En 中文
• Defect-rich BaZrO3/KB composites are synthesized as separator modifiers via a facile hydrothermal-calcination route. • Oxygen vacancies in BaZrO3/KB act as active sites to accelerate the bidirectional liquid-solid conversion of polysulfides. • The dual “adsorption-catalysis” mechanism of BaZrO3/KB suppresses the shuttle effect and ensures superior cycling stability.
