Abstract

Abstract : Sb-Doped high-voltage LiCoO2 was developed with unique properties. Abstract : Sb-Doped high-voltage LiCoO2 was developed with unique properties. In situ X-ray diffraction and density functional theory reveal that the introduction of Sb helps to shorten the Li + diffusion distance, increase the lattice spacing and keep the structural stability during deep lithiation, thus resulting in improved rate capability and cycling performance.
