Reaction Mechanism of LiNiO2 Synthesized in Oxygen Atmosphere by Pechini Method.

Journal of the Ceramic Society of Japan, 2002
Pechini process was known as an excellent method for the synthesis of LiNiO2 powder. Compared with the result of solid state reaction using NiO and Li2CO3 as reactants, Ni2O3 was the new compound found in Pechini-processed powder. In the present work, the role of Ni2O3 and the reaction mechanism for the synthesis of Pechini-processed LiNiO2 were ...
