Lithium iron phosphate batteries and ternary lithium batteries do not contain chlorine, so under normal circumstances they should not produce chlorine gas. If both of these batteries leak, they are less likely to produce gas and there may be differences in the type of gas produced. The chemical reaction after a leak will be affected by the leak site. The specific situation should be analyzed according to the chemical reaction conditions and electrolyte components to ensure safety. Therefore, if you find that the battery is leaking during use, be sure to take appropriate measures to avoid possible safety hazards.
Lithium iron phosphate batteries rarely leak after a bulge. It can be said that there is almost no leak. The main cause of the bulge is mainly caused by battery overcharging. Car using a batteryu 3.2V lithium iron phosphate, no leaks found. The actual photos are as follows for your reference.
I hope the above answers are helpful to everyone.
