64396 2025 eng lecture 0 -- -- -- Uncovering Li-ion Battery Degradation: Possibilities Offered by GD-MS Analysis Since their introduction, lithium-ion batteries (LIBs) have revolutionized the energy storage market, which they now dominate thanks to their high energy density, power capability, and efficiency.1, 2 Despite widespread adoption, global demand for LIBs is projected to grow by around 27% per year.3 This raises concerns about the availability of critical minerals essential to LIB production. Meeting future demand will therefore require next-generation LIBs—an ambition that hinges on a deeper understanding of the degradation processes that limit performance and lifetime. Because LIBs are chemically and physically complex systems, capacity fade stems from multiple degradation phenomena that act concurrently as cells age.4 In particular, the formation and growth of interfacial layers at the electrodes during repeated charge–discharge cycling make a substantial contribution to component degradation.5 Glow Discharge Mass Spectrometry (GD-MS) offers depth-resolved elemental and isotopic analysis of battery electrodes and has proven to be a powerful tool for tracking degradation in LIBs. Using a ASTRUM Swift GD-MS spectrometer, we identified degradation pathways in both cathodes and anodes across various cell chemistries, linking electrochemical behavior with changes in structure and elemental distributions. These insights help clarify the mechanisms that accelerate aging and capacity loss.
