Site Preference of Cobalt and Deuterium in the Structure of a Complex AB 5 Alloy Electrode: A Neutron Powder Deffraction Study

Autor: G. D. Adzic, J. McBreen, J.R. Johnson, Thomas Vogt, J. J. Reilly

Publikováno v: Journal of The Electrochemical Society. 146:15-19

The site preference of cobalt and deuterium in the charged and discharged state of a commercial-type metal hydride anode was investigated by high resolution neutron powder diffraction using an alloy with an altered isotope composition. In the alloy L

Function of cobalt in AB5Hx electrodes

Autor: James McBreen, G. D. Adzic, Sanjeev Mukerjee, James J. Reilly, J.R. Johnson

Publikováno v: Journal of Alloys and Compounds. :579-582

The role of cobalt in the behavior of AB 5 H x electrodes has been investigated. Alloy compositions were as follows, LaNi 4.3− x Co x Mn 0.4 Al 0.3 ( x =0, 0.2, 0.4, 0.75) and MmNi 4.3− x Co x Mn 0.4 Al 0.3 ( x =0, 0.75). Cobalt was found to decr
