Abstract

The microelectrode technique was applied to investigate the electrochemical behavior of LiNiO₂ which seriously influenced by water molecules. Cyclic voltammograms of humidified LiNiO₂ particles were compared to that of as-synthesized. As a result, a significant peak-potential shift was observed, which denotes that the reaction product caused by H₂O generates an electrochemical inactive material on the particle which prevents the Li⁺ insertion/extraction. The reaction product was considered to be NiO, and deterioration property has also been discussed. (C) 2000 Elsevier Science S.A.
