New cells are being developed for the electric vehicle and energy storage systems.

Prismatic and pouch cell are leading the new cells battery market.

But, many manufacturers have problems new cell types with high storage systems.

Most major battery manufacturer inspection every single cell as part of automated quality control by automated X-ray inspection systems.

Automated X-ray system examines defects such as bent metal or mild short.

The X-ray inspection should be conducted for the following reasons.

 If shorted, an unprotected Li-ion cell will vent with flame. Cells can also be damaged by stress related to heat, shock, vibration and incorrect charging or loading.

Lithium-based cells can build up an internal pressure under certain conditions, and a bloated pouch cell is proof of this.

Common causes of battery swelling include: Poor cell quality and design with low anode to cathode stoichiometric ratios, particulate contamination and Mechanical damage to electrodes induced either during cell assembly or from the product application.
