Mold stress relief

Partial certification program	Mold stress relief test requirements
UL certification	The cells were held at 70 ° C (158 ° F) for 7 hours in a fully convectively circulated drying chamber. Then carefully remove the sample and return to room temperature. Observe that the surface of the sample must be free from damage, such as the battery case is not broken or the electrolyte leaks. Result: No explosion, no fire, no leakage. In addition, the battery case does not burst, and the battery or any protective device cannot be perforated or leaked.
CQC certification	The battery was placed in a blast oven at 70 ° C ± 2 ° C for 7 h, then the sample was taken out and returned to room temperature. Result: The sample casing does not undergo physical deformation leading to internal composition exposure.
CB certification	The battery was placed in a blast oven at 70 ° C ± 2 ° C for 7 h, then the sample was taken out and returned to room temperature. Result: The sample casing does not undergo physical deformation leading to internal composition exposure.
