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

the secondary battery is leading the new battery market.

 

 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.

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.
