New battery inspection technologies: X-ray CT and Microscopy

Battery manufacturers face quality and process control challenges when battery components need to be inspected without being destroyed. The cells are inspected to map the electrode’s microstructure in 3D, the heterogeneities, foil stacking, welding joints, contacts, and their effect on battery aging and performance through several cycles of charging and discharging.

X-ray microscopy and computed tomography are non-destructive evaluation techniques that can generate detailed internal and external views of the full 3D battery microstructure without disassembling the battery. These techniques can be used to reveal critical structural defects in batteries, such as aging mechanisms or mechanical deformation effects, among others. Light and electron microscopy solutions round out the inspection portfolio, supporting surface defect analysis, roughness evaluation, cross-sectional measuring, particle contamination, etc. All of these capabilities speed up product development time, increase cost-effectiveness, and simplify failure analysis and quality inspection of lithium-ion cells and other deliverables of new battery technologies.

Advanced Manufacturing for EV Powertrain Production

Automotive manufacturers at all levels in the industry are facing changes not seen in nearly 100 years as the pivot to electrification accelerates. To successfully meet the associated new production challenges, a scalable, modular approach to manufacturing critical components such as EV power electronics is required.

In this session, we will present flexible, modular production methods, including laser welding, production platforms and high-speed part handling. Application examples of laser welding as a means to improve quality and flexibility as well as e-powertrain component assembly will be presented.
