摘要	LiNi1-xAlxO2 is one of new cathode materials for lithium batteries, which was a solid solution of LiNiO2 and alpha-LiAlO2. However, it is difficult to synthesize the solid solution with a high aluminum solid solubility because it is easy to decompose due to its negative synthesis enthalpy. A new synthesis method was obtained by studying the preparation conditions of LiNiO2 and alpha-LiAlO2, then LiNi1-xAlxO2 (x = 0-0.6) was synthesized successfully. The samples of LiNi1-xAlxO2(x=0-0.6)were studied by XRD and XPS, the results show that all samples have a single alpha-NaFeO2 structure and LiNi1-xAlxO2 solid solutions were synthesized. With the increasing of aluminum solid solubility x, not only Ni(Al)-O binding energy increased, but also lattice constant decreased and the ratio of c/a increased. As a result, the bedded structure was more obvious and the stability was enhanced.
