Key Points

  • This research aims to address capacity fading in lithium-sulfur batteries caused by lithium polysulfides.
  • Developed cobalt-manganese Prussian blue analogues for battery application.
  • Evaluated their effectiveness in enhancing the conversion of lithium polysulfides.
  • Compared with standard materials to assess performance improvements.
  • Achieved a significant increase in Coulombic efficiency compared to conventional materials.
  • Demonstrated up to 30% reduction in capacity fading over 100 cycles.
  • Revealed a notable enhancement in overall battery performance metrics.

Abstract

The practical deployment of lithium-sulfur (Li-S) batteries is severely impeded by the shuttle effect of soluble lithium polysulfides (LiPSs), which leads to rapid capacity fading and poor Coulombic efficiency. Although...
