What does a soft pack lithium-ion battery mean? Is the soft pack lithium-ion battery pack safe? What is a soft pack lithium-ion battery? What is the safety performance of lithium-ion battery packs? Lithium ion battery packs can be divided into three types based on the differences in packaging forms: cylindrical, square, and soft pack. Soft pack lithium-ion battery packs have the highest energy density among the three packaging forms of lithium-ion batteries. Soft pack batteries have become a very important technological route, with huge potential for the future. Today, let's focus on talking about soft pack lithium-ion battery packs.

What is a soft pack lithium-ion battery?

A soft pack lithium-ion battery is simply a liquid lithium-ion battery with a polymer shell. In terms of structure, aluminum-plastic film packaging is used, and in the event of safety hazards, the soft pack battery will only burst and crack at most. The advantages of soft pack lithium-ion batteries include good safety performance, light weight, large capacity, low internal resistance, and flexible design. The internal composition of soft pack lithium-ion batteries is not significantly different from that of square and cylindrical lithium-ion batteries. The biggest difference is that the soft pack lithium-ion battery pack uses aluminum-plastic composite film as the outer shell, while square and cylindrical batteries use metal materials as the outer shell.

Soft pack lithium-ion batteries refer to the material of the outer shell of the lithium-ion battery pack. If there is packaging on the outside, it is not easy to see, and the battery body must be seen. The weight of steel shell batteries is more important than that of batteries of the same volume, but it is not easy to distinguish between aluminum shell and soft packaging. However, soft packaging batteries are slightly softer than aluminum shell batteries and can easily deform when broken by hand.

Is the soft pack lithium-ion battery pack safe?
Generally speaking, soft pack lithium-ion battery packs are still very safe, as long as they are not subjected to severe impacts, punctures, or thrown into fire, they are basically very safe. It is safe to use it normally and strictly follow the instructions.

The safety of soft pack lithium-ion battery packs still needs to be improved. In fact, the root cause of combustion or even explosion in lithium-ion battery packs lies in the thermal runaway inside the battery. Essentially, "thermal runaway" is an energy positive feedback cycle process: an increase in temperature causes the system to heat up, which in turn makes the system hotter. Thermal runaway is a common phenomenon.

Which lithium-ion battery pack is safer?
Soft pack lithium-ion battery pack is safer. At present, many small lithium-ion battery assembly factories want to take advantage of the current hot situation and make a big profit. In the manufacturing process of soft pack lithium-ion batteries, there are no standards, and electrode manufacturing, battery assembly and other processes will have an impact on the safety of the battery. I bought a policy for lithium-ion battery packs, which provides 360 degree comprehensive protection from front to back, without affecting the performance and safety of lithium-ion batteries.
