Is the soft pack lithium battery pack safe?

Is the soft pack lithium battery really safe? The soft pack lithium battery is a liquid lithium battery with a polymer casing. In the structure, choose aluminum-plastic film packaging, the soft battery will only burst in the case of high safety risks. The soft-packed lithium battery has the advantages of good safety performance, light weight, large capacity, low internal resistance, and good planning. The internal composition of the soft pack lithium battery is not much different from the internal composition of the square and cylindrical lithium batteries. The biggest difference is that the soft-packed lithium battery shell uses aluminum-plastic composite film, while the square and cylindrical battery shells use metal materials for soft-packed lithium batteries. It is important to refer to the material of the lithium battery pack shell. If the outer packaging is not short, it is necessary to see the battery. The body, the weight and volume of the battery steel shell battery, but the aluminum shell and flexible packaging is not a short difference, but the soft and flexible packaging cell breaks short-term deformation than the aluminum shell. Is the soft-packed lithium battery pack safe? Generally speaking, the soft-packed lithium battery pack is still very safe. As long as it is not violently touched, pierced, or plunged into the fire, the roots are safe. It is safe for normal use and strictly in accordance with the instructions. The safety of soft-packed lithium battery packs needs to be improved. In fact, the root cause of the burning and explosion of the lithium battery package is the thermal runaway inside the battery. Essentially, thermal runaway is an energy positive feedback loop process: an increase in temperature will cause the system to heat up, which in turn will heat up the system. Thermal runaway is a very common phenomenon. Disclaimer: Some pictures and content of articles published on this site are from the Internet. If there is any infringement, please contact to delete.
