This study compares two nondestructive testing methods for the 3D visualization of defects at different depths inside a pouch battery cell: scanning acoustic microscopy (SAM) and X-ray computed tomography (CT). A manufactured pouch cell with eight electrode sheets is used for this investigation.
NI solutions are at the forefront of battery cell test system technology. These integrated hardware and software solutions are optimized for building automated test systems and advanced analytics with a reduced physical footprint. This approach enables comprehensive testing throughout the production line without time or space constraints.
The filled cells rest for a period of time, called soaking. The soaking process allows the electrolytes to fully saturate the electrode materials and ensures no air bubbles are trapped in the cell. At this stage, the battery cell looks like a battery, but it isn’t active.
Provide a hardcopy and electronic copy of the battery energy storage system SDS. Provide a copy of NETCC consumer information guide. Provide customer with the name and licence/accreditation number of the tradesperson who designed/signed off on the installation.
For this investigation, it was important to use components with controlled and known defects at defined positions inside the pouch cells. In order to make the battery cell as realistic as possible, electrodes sheets and separator foils extracted from commercially available cells were used.
Battery cell assembly is performed in a rigorously controlled environment to avoid degradation of the electrodes from moisture, dust particles, thermal expansion and compression on the materials. The electrodes are assembled in a battery cell through a process of cutting, stacking, packing, and sealing.
Due to inline speed requirements, it may not be feasible to inspect the whole area of a battery cell. In this case, to accelerate the measurement, images can be obtained from selected areas, lines, or points of a battery cell.
