Web1 de jul. de 2003 · This phase is a metastable form of LiCoO2 and is prepared by ionic exchange from P2-Na0.70CoO2. The O2-LiCoO2 system presents interesting fundamental problems as it exhibits several phase transformations upon lithium deintercalation that imply either CoO2 sheet gliding or lithium/vacancy ordering. WebLiCoO 2 adopts the α-NaFeO 2-type layered structure, with the Li ions residing between every two CoO 6 octahedral layers along [001] direction. The lattice oxygens are arranged in an -ABCABC- (O3 type) stacking sequence, and Li ions are positioned at interlayer octahedral sites (11, 12).
