The possibility of a lithium battery exploding is relatively small, but it is still possible to explode under certain conditions.
Lithium batteries are not very easy to explode, as long as it is a battery, there is a risk of explosion, but this risk probability is small. However, once it explodes, the larger the capacity of the lithium battery, the more powerful its explosion. Lithium battery explosion usually has two important inducements: short circuit and overcharge. Short circuit means that the positive and negative electrodes of the battery are in direct contact, while overcharge means that the battery is charged beyond its design capacity. Under normal circumstances, the battery management system and charging equipment will have certain protective measures to prevent short circuit and overcharge.
Although the probability of lithium battery explosion is not large, under certain special conditions, lithium batteries may still cause an explosion. These special conditions include:
1. High temperature environment? Lithium batteries are prone to thermal runaway in high temperature environments, resulting in uncontrolled internal chemical reactions, resulting in explosions.
2. Battery damage? If there is a short circuit or physical damage inside the lithium battery, it may cause a violent reaction inside the battery, and then cause an explosion.
3. Overcharge or discharge? Overcharging or full discharge may also lead to increased pressure inside the lithium battery, eventually causing an explosion.
4. Inferior batteries? The use of inferior or counterfeit lithium batteries, its safety is lower, more prone to explosion.
In addition, power lithium batteries usually have some signs before spontaneous combustion or explosion, such as the battery system failure light, the battery pack releases smoke, the battery pack appears swollen, and the smell of burning. Once these signs are detected, take appropriate measures immediately, such as stopping use, staying away from the vehicle, and calling 119 to contact the fire department.
In general, although the possibility of lithium battery explosion is relatively small, it is still necessary to pay attention to its safety during use, avoid use in high temperature environments, avoid battery damage, use qualified charging equipment and batteries, and regularly check the status of the battery.
