| dc.description.abstract | The identification and location of critical defects inside battery cells before the performance decreases or safety issues arise remains a challenge. Here we show images acquired from Scanning Acoustic Microscopy (SAM) as a non-destructive testing methods for the 3D visualization of defects at different depths inside a pouch battery cell. A manufactured dummy pouch cell with 8 cathode sheets is used for this investigation. SAM using a 15 MHz transducer in reflection mode can detect defects with a lateral resolution of 150 µm in 2 min. The time intervals of each micrograph have a length of 30 ns. The images are acquired with a resolution of with a pixel dimension of 50 x 50 μm²/ pixel. | en |
