Characterization and dissolution of hybrid electric vehicle (HEV) NIMH batteries for the development of a hydrometallurgical recycling method
Paper in proceedings, 2008

This paper deals with a study of the chemistry behind and the development of a hydrometallurgical method specifically targeted to recycle Hybrid Electric Vehicle (HEV) type NiMH batteries. The batteries are characterized through ICP-OES, SEM and XRD to determine phases and metal content. Different dissolution techniques are utilized and their respective effect on the subsequent solvent extraction process is discussed. Thus the selection of dissolution method is closely linked to the extraction and the selective stripping of the metals.
