WebLiCoO2), a three-layer rhombohedral compound; O2-LiCoO2, a metastable two-layer hexagonal compound synthesized through exchange reactions with P2-Na0.7CoO2 [14-16]; and spinel-like LiCoO2 (or LT-LiCoO2), synthesized by soft chemistry methods [17,18]. In the present investigation, we limit our study to thermodynamically stable three-layer HT- Web20 de ago. de 2009 · Abstract. A polytype of has been synthesized through an ion-exchange reaction. By exchanging for ions from an -mixed cobaltite, a stacking is obtained. It alternatively combines O2- and polytypes and corresponds to an O4 stacking. The phase crystallizes in the hexagonal system with cell parameters and . As the O2 phase, the , is …

Web1 de fev. de 2000 · O2-LiCoO 2 was prepared from Na 2/3 CoO 2 by ion exchange in LiBr dissolved in hexanol. The structure of O2-LiCoO 2 was investigated by X-ray diffraction and in situ X-ray diffraction during electrochemical charging. The possibility of application as cathode materials in rechargeable lithium batteries was investigated. Web1 de jun. de 2024 · On the metastable O2-type LiCoO2 journal, December 2001. Carlier, D.
