Will polymer lithium batteries and ternary lithium batteries explode?

Will polymer lithium batteries and ternary lithium batteries explode? Lithium batteries have become an indispensable part of digital devices, greatly improving their own power supply capabilities. However, in recent years, we often see various safety accidents caused by some lithium batteries. The most impressive is the explosion and fire of lithium batteries. Let's take a small series of energy storage polymer lithium batteries and ternary lithium batteries as examples to analyze the reasons why lithium batteries will explode. What is a battery explosion? According to national standards, any solid matter in the battery is discharged instantly and pushed to a distance of more than 25 cm. This is called an explosion. The identification method in the experiment is: place a circular grid on the experimental battery, and place the battery at the center of the circle, that is, 25 cm from both sides of the cage. If no solid part passes through the cage in the experiment, the battery does not explode. Will lithium polymer batteries explode? Polymer lithium batteries have the characteristics of light weight and small thickness. In more and more applications, although the replacement of other types of batteries is still in progress, among the types of lithium batteries, polymer lithium batteries have begun to replace ordinary lithium batteries in some areas. The polymer lithium battery uses aluminum-plastic soft packaging in structure, which is different from the metal casing of liquid batteries. When faced with safety hazards, liquid batteries are prone to explosion, while polymer batteries can only be equipped with air drums. As long as it is not damaged by humans, lithium polymer batteries are safe. Although relatively safe, polymer lithium batteries are easy to bulge. Once the air is swollen, the appearance returns to normal no matter how it is placed, and the battery is scrapped. Will the ternary lithium battery explode? The ternary lithium battery has good low temperature performance and can be charged at -20°C. However, the high temperature performance is relatively poor, especially in the high temperature environment, the ternary lithium battery is very dangerous, short circuit has the possibility of fire and explosion. Of course, most lithium batteries are protected by short-circuit and explosion-proof lines, but in many cases, this kind of protection circuit cannot work under various conditions, and the use of explosion-proof lines is very limited. Conclusion: Many things are a balance between safety and practicality. For example, many traffic accidents happen to cars every year, and the casualties caused by car accidents account for a large part of the abnormal deaths in our country. In addition, electricity is an important cause of fire. By the same token, there are billions of lithium batteries in mobile phones worldwide, and more lithium batteries will explode. Shouldn't we throw away our mobile phones? No car or electricity? There is no absolute safety in the world. There is a balance between safety and practicality. What we need to do is to minimize the danger. Polymer lithium battery safety protection and charging protection: When charging a polymer lithium battery, the upper limit of the charging voltage, the lower limit of the discharge voltage and the upper limit of the current must be set. This takes into account the battery's life, capacity and safety. Pay attention to short circuits: Li-polymer batteries are prone to short circuits during the charging process. Including: internal short circuit, external short circuit, etc. These conditions must be paid attention to to prevent accidental fires or explosions. Safety protection of the ternary lithium battery charging environment: The ternary lithium battery should be charged in a cool and dry place to prevent exposure to the sun. Keep away from fuel. Usage: Pay attention to the temperature when using the ternary lithium battery, and do not use the ternary lithium battery in an environment where the temperature is too high. Polymer lithium batteries and ternary lithium batteries have their own advantages and disadvantages. Battery companies should pay more attention to the safety of batteries, strengthen processing monitoring, and strictly guarantee the quality, so as to ensure the safety of lithium batteries. The above is the analysis of the reasons why polymer lithium battery and ternary lithium battery will explode.
