Overview

Interfacial B-O complexing improves lattice oxygen stability in LiCoO2 cathodes, suggesting enhanced performance.

Key Points

  • Stabilizing lattice oxygen at 4.6 V significantly improves capacity retention and rate performance.
  • Interfacial B-O complexing can inhibit peroxy-like species formation, reducing detrimental phase transitions.
  • The study utilizes in situ and ex situ characterization methods to analyze cathode stability.
  • This approach may provide a new avenue for enhancing high-voltage cathode performance in lithium-ion batteries.
