Abstract:
Safety and Durability are key issues in the development and application of Lithium Ion batteries, especially in automotive industry. In this paper, we investigate batteries after electrical short circuit and after overcharging by means of X-ray tomography. Focus of the work is the identification of structural damage in the interior structures. For our investigation we have chosen commercial LiFePO4 batteries that are widely used in many different applications.
