Characterization of electrode materials from spent batteries in the process of recovering valuable metals

The chemical and phase analysis of electrode materials from spent batteries is essential for identifying recyclable components and optimizing metal recovery processes. In this study, the electrode material from a spent cell of an unknown manufacturer was analyzed using inductively coupled plasma mass spectrometry (ICP-MS) and powder X-ray diffraction (XRD). XRD results revealed that the anode material consists of three crystalline phases: NiO, LaCoO3, and CeO₂, while the cathode material contains Ni(OH)₂ and Ni. ICP-MS analysis confirmed the presence of lanthanides in the anode material. Given that lanthanide deposits are concentrated in only a few countries, their recovery from spent batteries presents an opportunity for nations without natural reserves to secure their supply through recycling. This study highlights the potential for sustainable resource management by recovering metals from electronic waste.
