摘要
The La0.8Cm0.2Ni3.8Co0.3Al0.4 (AB(5)) (Cm: Cerium rich misch metal) alloy was mechanically mixed with carbon nanotubes at four different time periods, in order to study the effect on the mechanical milling and the electrochemical performance of the negative electrode of a Ni-MH battery. The microstructure and size particle during processing was analyzed by Xray diffraction. The morphology, examined by scanning electron microscopy, showed that the surface of the AB5 alloy was modified by carbon nanotubes. The electrochemical properties of the obtained materials were measured and discussed. Copyright (C) 2015, Hydrogen Energy Publications, LLC. Published by Elsevier Ltd. All rights reserved.
