Why do lithium batteries explode when entering elevators?

The reasons for lithium batteries exploding in elevators may include the following:

1. Overcharging or overdischarging: When lithium batteries are overcharged or discharged excessively, it may cause internal short circuits, thermal runaway, and other problems, leading to explosions.

2. Battery defects: If the lithium battery itself has manufacturing defects, such as unqualified electrode materials, electrolytes, etc., it may also cause it to explode in elevators.

3. Mechanical shock: During the operation of the elevator, vibrations and impacts may occur, which can cause internal short circuits in the lithium battery, leading to explosions.

4. High ambient temperature: Lithium batteries have a narrow operating temperature range, and high temperature environments may accelerate their internal chemical reactions, leading to explosions.

5. Short circuit: A short circuit inside a lithium battery can cause a large amount of heat to be generated in a short period of time. If it cannot be dissipated in time, it may also lead to an explosion.

6. Battery aging: As the usage time increases, the performance of lithium batteries will gradually decline. If severe aging occurs, it may also lead to explosions in elevators.
