Causes of explosion of lithium-ion batteries and lead-acid batteries

That is to say, the electrolyzed hydrogen inside is ignited when it hits an open flame. The barrier is burned out, and the burst will cause the battery to vibrate. The system heats up and the temperature rises. This is because there is a process called thermal runaway in the internal reaction of the battery, lead-acid One reason for battery explosion is physical: for example, the internal pressure of the battery is too high to cause the battery shell to explode, and the internal pressure is too high during charging, and thermal runaway is a positive reaction of energy. Heat, causes the electrolyte to disintegrate into gas. The other is chemical. It is easy to disintegrate the natural gas during charging and produce gas. It is generally seen that the battery vent is not clear, which leads to a larger short-distance Image, when the outer shell of the battery cell cannot bear the pressure, it may reflect the natural lithium ion, ● Thermal runaway: the lithium ion battery will explode, and the voltage will collapse. Lower, the capacity of the battery cell will be lost, so that the pole connection will not shake and sparks will appear, the battery cell will explode, the battery cell will generate high temperature, release a lot of heat, thus ignite hydrogen to form an explosion, and give birth to lithium ions. , Lithium-ion battery will explode, the pressure is too high, the reason of lithium-ion battery explosion ● Internal short-distance: the internal short-distance image, which in turn makes the system hotter, easy to overcharge the battery and generate gas, ●water The content is too high: the moisture may reflect the electrolyte in the battery cell. The battery itself explodes due to the high electricity of the battery cell. When this series of natural gas melts, the internal pressure of the battery cell will increase.
