Beneath The Surface: X-ray Analyses of Battery Materials and Structures 4. Non-Destructive Inspection of Batteries Using X-ray Computed Tomography

Did you know X-ray computed tomography (CT) can reveal structural deformities and defects and inspect for proper alignment of electrodes, separators, and electrolytes non-destructively?

X-ray CT is a powerful technique that allows non-destructive imaging of batteries. In this webinar, we will discuss important factors to consider when using X-ray CT methods to inspect batteries. We will also examine data analysis techniques to extract meaningful insight into battery structure and function.
