A battery failure analysis provides you with the insights and recommendations to help prevent future occurrences whether it is a failure, or the battery is not performing as expected

Longer-lasting energy sources and batteries continue to be pivotal for many industries. In order to increase performance and prevent failures a better understanding of degradation mechanisms is required.

Differentiating between the potential causes of a failure can be difficult, particularly when the failed product or system has been heavily damaged. It requires a versatile understanding of the components driving the electrochemical reactions within the cell as well as constraints placed on the battery by the application and environment. A comprehensive investigation is essential to determine if the failure was caused by external forces or an internal flaw.

Techniques & Methods of Li-Ion Battery Failure Analysis

We have developed a strategic and systematic methodology for conducting each failure analysis investigation. Our approach employs both non-destructive and deconstructive techniques to develop a well-rounded understanding of the failure. This interdisciplinary process allows our team to identify and categorize problems caused by the design, construction, storage, and operation of each battery.

We provide findings with potential mitigative actions to prevent future failures and extend battery life.
