Abstract
A series of lithium nickel composite oxides LixNi1âxO (0 < x â¤Â 0.3) were synthesized by rheological phase reaction method from LiOH·H2O and NiO. The structures were characterized by X-ray diffraction. The composite oxides are cubic with hexagonal super-lattices and their cell volumes have nice linear relationship to the lithium content. The reaction mechanism was investigated: at the beginning of reaction, LiNiO2 is formed rapidly from LiOH·H2O and NiO via oxidation and lithium inserting reaction, then LiNiO2 and excess NiO diffuse each other to form LixNi1âxO. The electrochemical properties of the compounds as anode materials for lithium ion batteries were discussed.
