Lithium battery will explode? But hydrochloric acid battery won't? Here comes the truth

　　You may have seen some news about the explosion of mobile phone batteries and the explosion of new energy vehicles, leaving the impression that lithium batteries are easy to explode. The news of hydrochloric acid battery is unheard of, which should be very safe. Therefore, the impression that lithium batteries are easier to explode than lead-acid batteries is formed. Is this really the case?

　　1、 What kind of battery is installed in your electric vehicle

　　When it comes to battery explosion, you may think of lithium battery explosion first! Most electric vehicles are still equipped with lead-acid batteries because they are cheap, but once an accident occurs, they will become lithium batteries. When it comes to battery explosion, we may think of lithium battery explosion first! Most electric vehicles are still equipped with lead-acid batteries because they are cheap, but once an accident occurs, they will become lithium batteries. According to foreign media reports, hundreds of Maseratis waiting to be exported to the Middle East were burned to skeletons when a fire broke out in an Italian port. The cause of the fire was that the high salinity seawater flooded the port, resulting in a short circuit explosion of the car battery.

　　2、 Hydrochloric acid batteries can also cause fire and explosion

　　Many people think that lead-acid batteries will not explode. Xiao Bian specially consulted the teacher who repaired lead-acid batteries. According to the old master, compared with lithium batteries, lead-acid batteries are slightly safer, but there are not many explosions. At present, the market competition is very fierce. In order to reduce the cost of batteries, some poor enterprises use low-quality battery panels, which can easily cause short circuits, even lead to battery fire and explosion. In addition, improper use of lead-acid batteries can also lead to fire and explosion. The main causes of lead acid battery fire are as follows: 1. The quality of the battery is very poor. 1) The poor quality or defect of the diaphragm makes the active substances of the electrode plate pass through, causing the positive and negative electrode plates to contact with each other in virtual or direct way; 2) The active substance on the electrode plate expands and falls off. Due to the excessive deposition of fallen active substances, the lower edge or side edge of the positive and negative plates contacts with the sediment, resulting in the connection of the positive and negative plates; 3) Formed when welding electrode groups; Lead flow "; not removed, or appears during assembly"; lead beans "; The diaphragm between the positive and negative plates is damaged during the charging and discharging process, leading to the connection of the positive and negative plates. 2. Abuse of the charger. Because the positive and negative poles of the charging ports are different between different chargers, the reverse connection phenomenon will occur. First, it will quickly charge your battery. Second, because the charger works in a wrong way, it is easy to cause the charger to short-circuit and burn. Therefore, the original charger or the charger of the same model should be used when charging. 3. Overcharging lead When the acid battery is overcharged, the water in the battery electrolyte is electrolyzed to generate hydrogen and oxygen. These are flammable and explosive gases. When the hydrogen content in the battery or air accumulates to the explosion limit, if an open fire occurs outdoors, it is very likely to burn or explode. When using electric vehicles and automobiles, pay attention to the use of batteries, especially when charging, which is most likely to cause accidents. I hope you can pay more attention to battery maintenance to avoid potential accidents.

　　In fact, as long as the battery is of poor quality, whether it is lithium battery or lead-acid battery, it will explode and catch fire (of course, the probability of normal use is very low). It is important to buy batteries from big brands and reliable manufacturers, operate the battery in a standardized way, and immediately repair the battery when it has problems.
