Selective Facet Growth and Surface Reconstruction Achieving Structure-Robust High-Voltage LiCoO <sub>2</sub>
slab gliding and H3/H1-3/O1 phase transition ensure structural stability at deep delithiation states. Based on the first-principles calculations and the structural and electrochemical characterizations, a correlation was clarified between the specifically exposed surface facets and the suppressed structural degradation. These findings underline the importance of the surface facets and will inspire ideas to improve the performance of high-voltage cathode materials by synergistically modifying their surface structure and crystal morphology.
