摘要：

The redox discharge process of the nickel oxihydroxide electrode (NOE) were followed by in situ neutron diffraction with the aim of getting a deeper insight into the phases and mechanisms involved, paying special attention to the second plateau. A set of deuterated samples was prepared to be used as a reference for the interpretation of the in situ patterns. Neutron diffraction experiments indicate that redox process is the same over both the first and second plateaus and corresponds to a phase transformation over the main part of the oxidation/reduction range and hence indicates that this phenomenon should not be associated to a structural transformation.
