Abstract in brief

  • The study proposes a novel pure carbon cathode made from an edgesitefree, topological defect-rich graphene-based material that enhances the performance of lithium-oxygen batteries without extra catalysts or mediators.
  • The material is synthesized through an advanced template method and high-temperature annealing, resulting in a mesoporous structure with nonhexagonal carbon rings, which improves electrochemical stability and capacity (up to 6700 mAh/g).
  • Experimental and theoretical analyses show that topological defects facilitate the formation of amorphous Li2O, boosting cycle life, with a flexible electrode achieving up to 307 cycles over 1535 hours, indicating potential for durable battery design.]
