Studies on Formation and Decomposition of the Layered Cobaltite LixNayCoO2
Figure 7
Electron diffraction pattern obtained from crystal aggregate of Li0.42Na0.36CoO2 subjected to ultrasonic dispersion (a) and its schemes (b, c). Black lines and white lines in (a) show nets of the (101)* cross-sections of LiCoO2 and γ-Na0.7CoO2, respectively. Indexing of the reflections for LiCoO2 (R), γ-Na0.7CoO2 (hex) and Li0.42Na0.36CoO2 (hex’) is shown: for (101)* cross-sections (b); for other Laue zones (c). Notations: bullet—reflections of (101)*NaCoO2; white circle—reflections of (101)*LiCoO2; gray circle, cross (numbers from 1 to 10)—reflections of NaCoO2 and LiCoO2 that not belonging to (101)* cross-section (see Table 1).
