With the rapid increase in the use of lithium-ion batteries in various industries, the safety performance of batteries has become increasingly prominent. Not only are lithium-ion batteries required to have excellent charging and discharging performance, but also higher safety performance. So why did the lithium battery catch fire or even explode, and are there any measures to avoid and stop it?

　　According to statistics, the global demand for lithium-ion batteries has reached 1.3 billion, and with the continuous expansion of application fields, this data is increasing year by year. Because of this, with the rapid increase in the use of lithium-ion batteries in various industries, the safety performance of batteries has become increasingly prominent. Not only are lithium-ion batteries required to have excellent charging and discharging performance, but also higher safety performance. So why did the lithium battery catch fire or even explode, and are there any measures to avoid and stop it?　　 The explosion of laptop batteries is not only related to the production process of the lithium battery cells used in it, but also related to the battery protection board encapsulated in the battery, the charge and discharge management circuit of the laptop, and the heat dissipation design of the laptop. The unreasonable heat dissipation design and charge-discharge management of the notebook computer will cause the battery cell to overheat, thereby greatly increasing the activity of the cell, and increasing the probability of explosion and combustion.
