Summary

In this episode of the Geladen podcast, hosts Daniel Messling and Patrick von Rosen interview Prof. Thomas Waldmann from ZSW, an expert in battery post-mortem analysis. The discussion focuses on the mechanisms of lithium-ion battery degradation, including lithium plating and SEI film growth, and how these are influenced by temperature, state of charge, and charging habits. Waldmann provides practical tips for extending battery life, such as avoiding full charges, moderating charging speeds, and storing batteries at moderate temperatures and partial charge. He also explains the difference between calendar and cyclic aging, and the role of the battery management system. The episode includes a segment on post-mortem analyses, where batteries are opened to investigate failure causes, and touches on recent studies about dynamic driving and its effect on degradation. The hosts also address listener questions about specific scenarios like hot car storage, fast charging, and LFP home storage in cold climates.
