High-resolution X-ray tomography uncovers subtle but critical anode overhang variations — helping battery developers align performance with safety standards.
In lithium-ion batteries, precise alignment between cathode and anode layers is more than a manufacturing target — it’s a safety requirement. In cylindrical cell formats like 18650 or 21700, even slight deviations in anode overhang can compromise performance, accelerate degradation, or introduce risk of thermal failure and the potential for fire.
This application note highlights how Tescan UniTOM XL micro-CT allows engineers to quantify overhang and related geometric variations across fully assembled cells. With 3D visualization and angle-resolved segmentation, Tescan’s workflow enables proactive design validation and tolerance optimization before failure occurs.
