Many people are now worried about the explosion of power banks. Let me break it down for you: First of all, why do lithium batteries explode? Due to overheating of the battery, a large amount of gas is produced inside and the battery explodes when the pressure reaches a certain height. What causes a battery to overheat? Overcharge, overdischarge, short circuit, mechanical damage (such as nailing). Indeed, in order to ensure the safety of users, there must be a protection circuit inside the power bank. In the event of overcharge, overdischarge or short circuit, the circuit automatically cuts off the power supply to protect itself. It is therefore very safe for normal use. But if the quality of this protection circuit is not good and it is damaged in advance, it will not be reliable. So you should not buy cheap informal products. When usingNormal operation, you should pay attention to monitoring during charging. When abnormal temperature rise is detected, the power supply should be cut off in time to avoid explosions, fires and other tragedies.
Pungent gases are certainly harmful to the human body, but the degree of danger is different. For example, lithium batteries are less harmful than lead acid batteries. The harmful gases produced by the combustion of lead-acid batteries contain heavy substances. metallic lead, and inhaling a small amount will have no effect. If you inhale too much, you will definitely get lead poisoning, but if you just breathe, you will probably be fine. There is no need to be afraid.
