Why does the 12V lithium battery explode or burn?

Why do 12V lithium batteries explode or burn? Since the invention of lithium batteries, traditional 3A alkaline batteries and nickel-metal hydride batteries have gradually moved towards the altar of digitalization. But I don’t know when it will start. We are talking about 12V lithium batteries, which are naturally related to explosions, but don’t lithium batteries claim to have high safety? Why do you travel often? The following author can take you to analyze the explosion of lithium batteries , Why does the 12V lithium battery explode or burn? 12V lithium battery. Why does JPG explode or burn a 12V lithium battery? First, analyze the structure and characteristics of the 12V lithium battery. The protection board: When the 12V lithium battery is overloaded, overcharged, overcharged, or overheated, the protection board automatically disconnects the power. It is a safety protection cover for lithium batteries. Once there is a problem with the protective plate, there will be no guarantee that the battery will have a problem, and it may burn or explode. Battery: The battery is equivalent to the core of a 12V lithium battery. Lithium iron phosphate and polymer lithium batteries have long life, high safety, and no memory. The failure of the lithium iron phosphate battery is only burning and will not explode. Process technology: Process technology is the key to determining the quality of lithium batteries, and the processes of different manufacturers will be different. Inferior batteries are more likely to explode or burn in the same way. The damage of counterfeit products is also an important factor leading to multiple explosions of lithium batteries, so you must choose a reliable manufacturer when buying 12V lithium batteries. Acupuncture: The damage caused by acupuncture to cells cannot be repaired. The damaged part will cause a local short circuit and a large amount of heat will cause the internal temperature of the battery to rise to the positive thermal decomposition temperature. Impact: When the lithium battery is impacted, the over-voltage loss on the electrode will cause heat to cause the solvent to react with the negative electrode. The released heat further heats the battery and promotes the thermal decomposition reaction of the positive electrode, causing the heat to lose control. Short circuit: A large amount of heat appears when the current flows through the battery, which causes the battery to heat up and the battery temperature rises to the positive electrode decomposition temperature. The decomposition of the positive electrode causes the battery to lose control of heat, resulting in combustion or explosion. Ambient temperature: When the ambient temperature is too high, the battery is like a reaction chain, and the cathode material will also undergo thermal decomposition in such an environment. Under such a sealed condition, the battery will expand and the pressure will burst when the pressure reaches the limit. Conclusion: In general, in addition to the hazards caused by fake and inferior products, the explosion caused by improper operation of 12V lithium batteries during use is also a major cause. When using a 12V lithium battery, you must strictly abide by the rules of use to prevent accidents. Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
