What are the causes of battery explosions? Batteries are also a common type of battery. Improper use can cause the battery to swell, resulting in side effects such as energy loss and unstable internal voltage. There is also the danger of excessive use of batteries. Next, the editor will introduce to you the causes of battery explosions? I hope friends can pay attention when using it.
1. Excessive internal pressure of the battery can cause an explosion of the battery casing
During the process of charging a battery, especially at the end of charging, due to overcharging, water decomposes into hydrogen and oxygen, short circuits, severe sulfurization, and a sharp rise in electrolyte temperature during charging, it is easy for a large amount of water to evaporate. If the vent hole of the charging hole cover is blocked at this time, too much gas cannot escape, and the internal technical structure of the battery is simple, the pressure will rise very high, which will cause deformation of the battery slot. When the internal pressure reaches a certain pressure, the joint of the battery slot cover or other weak points will burst. Therefore, when charging the battery, it is important to pay attention to changes in internal pressure.
2. Hydrogen gas will cause battery explosion when exposed to open flames
If 80% of the overcharge is used for electrolyzing water, and the hydrogen content inside the battery is greater than the explosion range, when the oxygen content in the battery or air accumulates to the explosion limit, an explosion will occur when encountering an open flame. After research, it was found that the explosion of batteries belongs to the branch chain explosion reaction, which mostly occurs during overcharging. When the charging voltage of the battery is higher than a certain charging voltage and there is a possibility of explosion under the condition of simultaneous ignition.
3. The exhaust hole of the battery is blocked
When the exhaust hole of the battery is blocked, the battery will first burst, which will cause vibration of the battery. If the pole connection is not secure, sparks will be generated, resulting in an explosion.
These three are the causes of battery explosions. Friends must pay attention to them in daily use, especially during the process of charging the battery, to avoid battery explosions.
