Controlling 001 Facet Exposure in TiO Nanoflakes for Enhanced Polysulfide Trapping in Lithium-Sulfur Batteries

Key Points

• The research aims to address the limitations in lithium-sulfur battery performance caused by the shuttle effect of soluble lithium polysulfides.
• Developed modified separators to enhance the trapping of lithium polysulfides.
• Controlled {001} facet exposure in titanium dioxide nanoflakes.
• Conducted comparative analyses on battery performance using different separators.
• Enhanced polysulfide trapping observed with modified separator compared to conventional designs.
• Significant reduction in the shuttle effect leads to improved cycling stability.
• Rechargeable lithium-sulfur batteries exhibited better overall performance metrics.
