Why should lithium batteries pay attention to fire prevention?​

Why should lithium batteries pay attention to fire prevention? Many people may be familiar with lithium batteries from mobile phones. In fact, it is used in many home appliances. Undoubtedly, the advantages of lithium batteries such as light weight are making them popular and applied. However, did you know that if you use it carelessly, it will also make you "fire"? Next, Taiyu Battery will explain to you:

Lithium batteries have the advantages of light weight and low temperature resistance (-40°C). Lithium batteries with a thickness of 0.3mm and the size of a postage stamp can be used continuously for more than 5 years. In recent years, the current alkaline dry batteries and manganese batteries are being phased out. in many home appliances and cell phones.

Different from the zinc chloride and potassium hydroxide water-soluble electrolytes of current manganese batteries and alkaline dry batteries, lithium-ion batteries use organic solvents. The positive electrode of lithium battery is made of manganese dioxide, lead fluoride, sulfurous chloride and other materials. Compared with zinc chloride used in general battery negative electrodes, the lithium metal foil used in the negative electrode has a strong ionization tendency and a large voltage difference between the positive and negative electrodes, which improves the working efficiency of the lithium battery.

Why should lithium batteries pay attention to fire prevention?
However, power batteries often experience heat and combustion during use, which may affect the use of the main unit in the lightest case, or cause a fire by burning the main unit in severe cases. According to reports, there have been many domestic fire accidents caused by the heating and burning of lithium batteries in Japan in recent years.

So why do lithium batteries heat up and burn? After many materials in the original lithium battery come into contact with water, a violent chemical reaction can occur and a large amount of heat energy is released, resulting in heat generation and combustion. The manganese dioxide of the positive electrode of the lithium battery can generate heat with only a small drop of water. After the sulfurous chloride in the lithium battery comes into contact with water, it releases heat energy while generating hydrochloric acid and sulfur dioxide. Several factors make the lithium battery a "tinder" in life. Therefore, people must pay attention to waterproof and prevent damp. After all kinds of hosts are out of use, the lithium battery should be removed and stored in a dry and low temperature place to prevent the occurrence of household fire accidents caused by improper use of lithium batteries.
