Abstract: First steps using Soft X-Ray Emission Spectroscopy for lithiated Silicon-based Anodes 

Recently, Fraunhofer ISE has expanded the battery research department with a SEM from JEOL, equipped with detectors for EDS, EBSD, and SXES analysis. The first research focus is the study of lithium distribution in various battery components, especially in silicon-based electrodes. Initial research objective is to examine lithium content in silicon-based electrodes as a function of state of charge (SOC). Understanding how lithium is distributed in these electrodes is essential for optimizing battery design and performance. In addition, our future research will address "lithium trapping", where lithium remains trapped in silicon particles even after numerous charge/discharge cycles, resulting in gradual lithium loss. Investigating this phenomenon will enable us to develop strategies to mitigate lithium entrapment and improve the efficiency and lifetime of lithium-ion batteries.
