Why do lithium batteries explode? According to experts, the dangers of fire, combustion and even explosion have not been completely eliminated. A vehicle collision may cause the positive and negative data of the battery to break through the gap, and the braking and energy can be quickly charged. The current battery is currently super high (currently in electric vehicles, the braking energy recovery can be as high as 250 ~ 300 amperes. If the super high power cannot be split, this will Causes a short circuit). Other reasons may cause short circuit, temperature increase, incineration or even explosion. In addition, the electrolyte of a lithium battery is an organic electrolyte, and these materials are relatively easy to contact with air.

Therefore, lithium batteries have high requirements on the environment. Even slight environmental discomfort can cause explosions and fires, and they cannot be used at will like lead-acid batteries.

The development of lightweight lithium batteries seems to be short, but its technology and equipment investment is large, and the standardization and systemization of assembly requires researchers. A small technical error will cause cell damage or blasting. Therefore, currently only large companies are normal. The emergence of productive forces has few sellers in rural and urban areas. Some small manufacturers have poor technical strength, slack production and assembly, and minimalism, causing trouble.

Therefore, when using a lithium battery, you must pay attention to its application environment. For example, the operating temperature of a general lithium battery is lower than 50 ℃, and it should not be placed in a fire or short circuit.
