Abstract

Electrochemical deintercalation of Li from the metastable O2-LiCoO₂ phase has been investigated up to the composition Li_0.15CoO₂. The single-phase domains that separate the voltage plateaus observed have been characterized by X-ray diffraction. The succession of phases observed upon deintercalation results from reversible sheet gliding or lithium/vacancy ordering, leading to the sequence 02, T#2, T#2', 06, 02, 02. In particular, the T#2 stacking, similar to the T2 phase reported by Dahn and co-workers for the Li_2/3Ni_1/3Mn_2/3O₂ phases, corresponds to oxygen ions not sitting on the three positions of a triangular lattice, hence the # character is used. It exhibits very distorted tetrahedral sites for Li. The 06 stacking exhibits two kinds of CoO₆ octahedra, which might allow Co³⁺/Co⁴⁺ ordering in alternate sheets. The most deintercalated O2-Li_0.15CoO₂ phase has never been reported before. Electronic properties and ⁷Li magic-angle spinning nuclear magnetic resonance show a transition to a metallic state for x< 0.94 (appearance of the T#2 phase with x = 0.72). These stacking changes are proposed to result from the minimization of electrostatic repulsion, except for T#2' (x = 0.50), which is believed to result from a Li/vacancy ordering.
