"Two-in-one separator capturing and reutilizing polysulfides for high p" by Sung Joon Park, So Yeon Yang et al.
The lithium-sulfur battery (LSB) is highly attractive as a next-generation class of batteries because of its high theoretical energy density and cost-effectiveness. The LSB has not yet been commercialized, however, due to performance fading caused by the severe shuttle reactions of polysulfides. Herein, we have strategically designed a multifunctional composite separator by coating ordered mesoporous Mn2O3 (m-Mn2O3) together with highly conductive Super P (SP) on polyethylene (PE) separators. The coating layer is intentionally designed to cause spontaneous chemisorption and reutilization of di...
