Ultrasonic Scanning for Lithium-ion Battery Inspection

With the rapid development of electric vehicles, energy storage and other fields, the application of lithium-ion batteries is becoming more and more widespread. As a result, the testing technology of lithium-ion batteries has also had higher requirements. Ultrasonic scanning, as a non-destructive testing technique, has good application prospects for lithium-ion battery inspection. In this paper, we summarize the research progress of the application of ultrasonic scanning in lithium-ion battery inspection in recent years from three aspects: principle, method and result, and prospect the development of the application of ultrasonic scanning in lithium-ion battery inspection.
