Structural degradation of cathodes in Li-ion batteries

Li-ion batteries (LIBs) are currently considered as the most promising and advanced energy storage
technology. However, a few scientific challenges in LIBs remain. That includes a fundamental understanding
of degradation processes in active materials in LIBs and how these processes affect the performance of a
battery. It is clear that a large number of LIBs will be produced in the nearest future, making recycling an
important process for sustainable and responsible production. However, recycling cannot be performed
without a clear understanding of the degradation processes occurring in the cell during electrochemical
cycling. We will study NCM and LFP-based cathodes at different stages of their lifetime. By measuring these
during battery operation, we aim to get a better understanding of how the aging of the electrode influence its
performance providing a guideline for the future recycling.
