Overview

Depth-resolved cathodoluminescence spectroscopy observes oxygen vacancies in LiPON/LiX V2O5 interfaces, suggesting battery degradation impacts.

Key Points

  • This research aims to investigate the formation and evolution of oxygen vacancies at LiPON/LiX V2O5 interfaces during electrochemical cycling.
  • Utilized depth-resolved cathodoluminescence spectroscopy (DRCLS) to observe oxygen vacancies
  • Assessed the spatial distribution and intensity of emission signals as a function of cycling
  • Employed density functional theory to understand defect emissions
  • Oxygen vacancies were detected near the interface before electrochemical cycling began
  • Signal intensity of oxygen vacancies increased with cycling, penetrating deeper into the electrode
  • Electrochemical performance showed poor Coulombic efficiency and a capacity drop of 15% over 50 cycles
