The heat treatment by vacuum annealing was carried out at 700 oC, 800 oC, 900 oC and 1000 oC. The microstructure and phase composition of the alloy have been investigated using inductively coupled plasma - atomic emission spectrometry (ICP-AES), scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDX) and X-ray diffraction analysis (XRD). The battery anode was prepared using a mixture of the pulverized alloy with carbon black and polytetrafluoroethylene as a binder.366-370openAccessmicrostructureelectrochemistrylanthanum hydridesmagnesium hydridesnickel hydridesaluminium base alloyscobalt base alloyshydrogen storageArtigo de periódico89910.4028/www.scientific.net/MSF.899.366
