Will lead-acid batteries explode?

When it comes to battery explosions, the first thing that comes to your mind is that lithium batteries may explode! However, according to foreign media reports, a fire broke out in a port in Italy. Hundreds of Maserati vehicles waiting to be exported to the Middle East were burned to the point where only the skeleton was left. The cause of the fire was that the high-salt water flooded the port, causing the car battery to short-circuit and explode. Many people think that lead-acid batteries will not explode. Sister Quan specifically consulted the teacher who repairs lead-acid batteries. According to the teacher: Compared with lithium batteries, lead-acid batteries are still very safe and explode. Very few, but the current market competition is fierce. In order to reduce battery costs, some unscrupulous merchants use inferior plates, which can easily cause short circuits and even cause battery fires and explosions. In addition, improper use of lead-acid batteries may also cause fires and explosions. . The main reasons for the fire of lead-acid batteries are as follows: 1. Poor battery quality 1) The separator is of poor quality or defective, allowing the active material of the electrode plate to pass through, resulting in virtual or direct contact between the positive and negative plates; 2) The active material on the electrode plate swells and falls off. Due to the excessive deposition of the fallen active material, the lower edges or side edges of the positive and negative plates are in contact with the deposits and the positive and negative plates are connected; 3) The lead flow formed when the electrode group is welded If it is not removed, or there are lead beans between the positive and negative plates during assembly, the separator is damaged during charging and discharging, and the positive and negative plates are connected. 2. Abuse of the charger. Since the positive and negative poles of the charging port between different chargers are different, it will have reverse connection. First, it will quickly charge your battery and damage it. Second, because the charger operates in a wrong way. , It will easily cause short-circuit and burning to the charger, so when charging, you should use the original or unified charger. 3. Overcharged lead-acid batteries will electrolyze the moisture in the battery electrolyte when they are overcharged. After being electrolyzed, hydrogen and oxygen will be produced. These are flammable and explosive gases. When the hydrogen content in the battery or in the air When the accumulation reaches the explosive limit, it is very likely to burn or explode when exposed to an open flame outside. When you use electric vehicles and cars, you must pay attention to the usage of the battery, especially when it is charging, which is the most likely to cause accidents. I hope you will pay more attention to the maintenance of the battery to avoid potential accidents. Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
