“…The XRD pattern of LiNi 0⋅8 M 0⋅2 O 2 (M = Mg, Ca and Ba) sample shows a well defined peak at 2θ = 19° and the other less intensity peaks at 36° and 44°. The intensity vs diffraction angle peak data indicates the compound to crystallize in rhombohedral systems (space group, R3m) (Mohan Rao et al 2001). There are no additional peaks found which indicates the absence of unwanted phases.…”

“…Powder samples of NiF 2 , NiCl 2 , NiBr 2 , NiI 2 , NiO, Ni(OH) 2 , LiNiO 2 , CoF 2 and CuO were evaluated by M-edge XAS at energies from 50 to 100 eV. LiNiO 2 was synthesized by a hightemperature combustion method (Rao et al, 2001) at Argonne National Laboratory, USA. All other samples were purchased from Sigma-Aldrich (purity = 98.5%-99.5%) and used without further purification.…”

“…This is reflected by the split of the (006) and (102) peaks and of the (108) and (110) peaks in the XRD patterns. It is evident that electrochemically reactive LiNiO 2 showed a larger integrated intensity ratio of the (003) peak to the (1040 peak (I 003 /I 104 ) and a clear split of the 108 and 110 peaks in its XRD patterns 13 This indicates that the R-factor increases as the degree of cation mixing increases [14][15][16] . Figure 3 (a) and (b).…”
