Abstract

In this study, we demonstrated the surface reaction in a LiCoO₂/Li cell under high voltage condition and characterization of the composition and properties of electrode-electrolyte interface by 2D correlation analysis. 2D Raman correlation spectra revealed that the extraction of Li⁺ leads to the formation of surface components including Li₂O and Co₃O₄ and structural distortion in hexagonal LiCoO₂ structure.
