// Post-mortem analysis

We are specialised in post-mortem analysis for analysing damage and assessing new cells. The analytical results are essential for understanding ageing processes, potential safety risks and for optimising the cell design.

An official expert with over 20 years of experience in battery research and certified by the Bundesverband Deutscher Sachverständiger des Handwerks (BDSH - German Federal Association of Technical Trade Experts) is responsible for performing damage assessments at ZSW.
