Lithium batteries are more likely to explode.
Compared to lead-acid batteries, lithium batteries are more prone to explosions and fires, mainly because their electrolytes are different.
Since the electrical substances produced by lithium batteries and lead-acid batteries are different, lead-acid batteries are sulfuric acid substances, while lithium batteries are substances lithium-ion organics. Sulfuric acid is not affected by the fire. , while lithium ions are likely to ignite. Therefore, lithium batteries are prone to explosion. In other words, lithium batteries have a protection program. Once the protective layer is damaged, the lithium battery will generate a lot of heat and open fire. to arrive at.

The risk of explosionon of a lead acid battery is usually very low, unless it is a poor quality product, so at the moment the advantage of buying it in a regular store appears. Because the initial cost of lead-acid batteries is not high and they are cheap to sell, it is impossible for most manufacturers to produce lower-quality lead-acid batteries.
Unless the battery is a used battery, used lead-acid batteries typically fail within a few days and are prone to explosions and fires. For safety reasons, it is therefore preferable to buy new batteries.
Why do electric vehicles catch fire when charging? The editor gives four reasons here.
The first reason is mainly that we overload the battery. This can cause the battery to heat up, expand, or even explode.
The second reason isthat most electric vehicle batteries that burn or explode are actually lithium batteries. These vehicles are the ones we often see on TV or on Douyin.
This electric vehicle battery is divided into two types, one is lithium battery and the other is lead acid battery. Lithium Batteries Most lithium batteries are mainly composed of 18650 cells, and 18650 is like an AA battery. Dozens of them are strung together, piled up together, and then placed in a protective bag.
When charging, do your best not to bring lithium batteries home or push lithium battery electric vehicles into the hallway to recharge. Once a fire breaks out, it will cause significant property losses. Of course, not all ideas can be mastered. The probability of an explosion is approximately one in 100,000. Ifone of the tens of thousands of electric cars lying around explodes, it will be quite powerful. Therefore, everyone should try not to take it home or park it in the hallway for charging during this charging period, so as to avoid fires in advance.
The third reason is that in our lives, some residents like to use flying wires for charging, which can easily lead to voltage instability. In addition, our wires rub against the wall for a long time, which causes the wires to wear out, causing leakage and short circuit, which may lead to fires.
The fourth reason is that the lifespan of our charger is generally only two to three years, and some people buy poor quality chargers at low prices, and this safety risk also arises.
The fifth reason is that we only modify other parts such as the frame, thiswhich results in uneven quality between them, and most of them are flammable and combustible materials. Once a short circuit fire occurs, it will promote the spread of fire.
