The Ni/H 2 self-discharge kinetics were studied by means of Ni/H 2 cells equipped with a pressure sensor to determine the time-dependence of cell pressure. The cell pressure variation was found to depend strongly upon cell state of charge (e.g., whet

To investigate the self-discharge mechanism in Ni/H 2 cells, the interactions of hydrogen with the β-NiOOH and γ-NiOOH nickel oxyhydroxide phases were simulated in a water-loaded autoclave as functions of both temperature and pressure. Under such c

We report on a detailed study of the γ-NiOOH → β-Ni(OH) 2 phase transformation previously proposed as the origin of the second low voltage plateau, occasionally observed during the discharge of Ni-based alkaline batteries. This was done by means

A thorough study concerning the formation of LiNiO 2 by a low temperature exchange reaction under hydrothermal conditions has been made. LiNiO 2 with low degree of cationic mixing and good electrochemical performances was prepared from NiOOH. LiCoO 2

The nickel oxyhydroxide electrode (NOE) that acts as the positive electrode in Ni-based rechargeable alkaline batteries was studied. A survey of the influence of crystal-chemistry factors (nature and ratio of the various nickel hydroxide phases), cyc

A large variety of pure {beta}-Ni(OH){sub 2} and cobalt-substituted nickel hydroxides Ni{sub 1{minus}x}Co{sub x}(OH){sub 2} of well-controlled chemical composition, particle size, and morphology have been prepared and characterized by x-ray, transmis
