Analysis of aging phenomena of lithium-ion battery anodes via energy-dispersive X-ray spectroscospy
Get PDFThe evaluation of lithium-ion batteries (LIBs) is crucial for improving their safety, sustainability, and lifespan. Accurate assessments are necessary for determining the end-of-life of batteries, exploring second-life applications, and ensuring safe storage and transportation. As part of the SUSTAIN project, which aims to develop a database for a rapid analysis device for LIBs, this thesis focuses on examining the anodes of aged LIB cells. Specifically, 18650 NMC/graphite batteries, strategically cycled to induce lithium-plating (Li-plating), are studied and compared to unaltered reference cells. Through scanning electron microscope (SEM) and energy-dispersive X-ray spectroscopy (EDS), different morphologies of layers were found and chemically characterized. The research investigates changes in the elemental composition, providing valuable insights into the aging mechanisms and the formation of layers on top of the graphite anodes
