Flexible packaging lithium battery

　　The flexible packaging lithium ion battery is just a liquid lithium ion battery with a polymer shell. The structure is packed with aluminum plastic film. In case of potential safety hazards, flexible packaging batteries can only explode and crack at most.

　　1. Advantages of soft packed lithium-ion battery: Compared with hard packed lithium-ion battery, it has the advantages of small size, light weight, high specific energy, high safety, flexible design, etc. Specific advantages are as follows:

　　(1) Flexible packaging lithium ion battery has good safety performance, rather than exploding like aluminum battery with steel shell.

　　(2) It is light in weight, 40% lighter than the steel case lithium battery with the same capacity and 20% lighter than the aluminum case battery.

　　(3) The capacity of the flexible packaging lithium ion battery pack is 10-15% higher than that of the steel case battery with the same specification and size, and 5-10% higher than that of the aluminum case battery.

　　(4) The internal resistance of the soft battery pack is less than that of the lithium ion battery pack. At present, the minimum internal resistance of domestic flexible packaging battery cell can be less than 35m, which greatly reduces the self power consumption of the battery.

　　(5) Flexible design, the shape of flexible packaging lithium ion battery pack can be customized according to customer needs, and new battery models can be developed.

　　Hard packed lithium battery

　　(1) Baidu Encyclopedia does not introduce many hard packed lithium ion batteries. Tuopai Xiaobian will not introduce hard packed lithium ion batteries in detail here. Let's take a look at the difference between hard packed lithium-ion batteries and soft packed lithium-ion batteries. What is the difference between soft packed lithium-ion batteries and hard packed lithium-ion batteries? Hard packed lithium ion battery. The difference between JPG soft packed lithium-ion battery and hard packed lithium-ion battery mainly refers to the material of the packaging shell of the lithium-ion battery. If there is packaging outside, it is not easy to see. You must have seen the lithium-ion battery. The weight of the steel case battery will be more important than the weight of the same battery, but it is not easy to distinguish the aluminum case battery and the flexible packaging battery, but the flexible packaging battery will be slightly weaker than the aluminum case battery, and it is easy to deform by hand.
