Reliable energy storage and efficient renewable energy production are key to a sustainable future. But fast-changing global vehicle fleets and electrical production systems will require exponential growth in the number of battery cells produced. Excillum’s MetalJet X-ray sources enable full inline CT scanning capabilities with micrometer resolution, giving manufacturers the high-speed, high-resolution 3D imaging they need to ensure product safety and quality at the highest throughputs.
Inline X-ray computed tomography (CT) is a powerful inspection technique that can further reduce the risk of defects and recalls, compared with today’s 2D X-ray inspection techniques. However, to achieve the levels of inspection coverage, throughput and resolution necessary for high-volume battery production, a high-power X-ray source with a micrometer-sized X-ray spot is necessary. The Excillum MetalJet E1+ 160 kV source makes this possible, achieving a full scan with micrometer resolution in just one second, or less.
An internal feature to be inspected during manufacturing of a battery is the anode overhang. The anode should be dimensioned to overlap the cathode. To produce this with repeatability puts high demands on the manufacturing and process precisions. To inspect this with precision in prismatic battery cells, X-ray CT is a pre-requisite. Furthermore, to have a 3D model of each produced battery cell can be very helpful for forensics in case a battery cell would fail in the field – in order to minimize a recall to an as small volume as possible.
