Fire

The phenomenon where visible substances leak from a battery cell, module, battery pack, or system to the outside of the test object.

It refers to the measurement of the potential severity of hazards.

The sudden release of a significant amount of energy that generates a pressure wave or jet of material, which may cause structural or physical damage to the surrounding area.

The phenomenon where defects within a lithium battery, such as burrs or lithium dendrites, pierce the separator, causing contact between the positive and negative electrodes.

Dendritic metallic lithium formed when lithium ions are reduced during the charging process of a lithium-ion battery.Note: The form of lithium when it appears on the negative electrode side is not necessarily lithium dendrites; collectively, it's referred to as lithium plating.

No unexpected risks have occurred.
