12V lithium-ion battery is a common battery product type, energy storage power supply, electric tool product application is common, 12V lithium-ion battery process is relatively simple and mature, it is not easy to explode combustion, when encountering a burning explosion, we First analyze the structure and characteristics of the battery; protective board: If the lithium ion battery is charged separately, it is generally the power-off protection of the charger to protect the lithium ion battery in the case of protective plate overfill. However, in some external devices operated by the power adapter, the protective plates used by the 12V lithium-ion battery are highly reliable. When the protective plate fails, it is easy to cause a lithium ion battery explosion combustion accident; Core: The battery is the basic part of the 12V lithium-ion battery.
The quality and safety account for a large part of the proportion. In the same situation, the incomplete battery explosion or the chance of combustion is greater. If the fake, the fake is also caused more lithium-ion battery explosions Important factors.
Choosing the quality of the battery to reduce the accident of the battery explosion; process technology: Process technology is the key to determining the quality of lithium-ion battery, different manufacturers technology will not be the same. Therefore, when purchasing 12V lithium-ion battery Be sure to choose a reliable manufacturer; acupuncture: When the lithium ion battery receives the needle injury, it cannot be repaired, the damaged portion will cause local short circuit and have a lot of heat, so that the internal temperature of the battery is raised to the temperature of the positive electrode heat decomposition. It can cause the lithium ion battery to be fiercely burned, which induces the chain reaction of the entire set of batteries, which ultimately leads to an explosion.
So it is necessary to completely prevent contact with the sharp object when using a 12V lithium-ion battery; impact: impact can cause a lithium ion battery to become a deformation, when hit When the strength is too large, it will even cause an misinterpretation in the lithium-ion battery, resulting in an abnormal heat generation, and the heat released is further heated, which causes the positive thermal decomposition reaction to occur, resulting in the loss of heat; short circuit: short circuit is the most direct resulting 12V lithium ion battery The culprit of the explosion, the short circuit is divided into internal short circuits, and the internal short circuit usually occurs in the battery leads due to abnormal wear that occurs during use, making short circuits caused by the insulating layer peeling and battery contact. The internal short circuit of the lithium-ion battery also leads to a serious accident. Ambient temperature: When the ambient temperature is too high, the inside of the battery is like a reaction chain, and the positive electrode material also occurs thermally decomposes in such a environment.
When such a seal, the electrical core can, the pressure to the limit of the limit will burst.
