The difference between soft pack lithium ion battery and hard pack lithium ion battery

The soft-pack lithium-ion battery is 40% lighter and 20% lighter than the steel-case lithium-ion battery and aluminum-case lithium-ion battery of the same capacity. In terms of weight, soft-pack lithium-ion batteries are much lighter than hard-pack lithium-ion batteries, but the important weight ratio lies in the weight of the two casings. ●The capacity of the soft-packed lithium-ion battery is 10% to 15% and 5 to 10% higher than that of the steel shell battery and aluminum shell battery of the same size. Although in terms of capacity, soft-pack lithium-ion batteries do not have much higher capacity than hard-pack lithium-ion batteries, there is a certain gap between the two. In areas with high capacity requirements, the application of soft-pack lithium-ion batteries is still higher. For hard-packed lithium-ion batteries. ●Shape Because the internal battery of the soft-packed lithium-ion battery is liquid, its shape can have a variety of shapes under normal circumstances. This characteristic is better than that of the hard-packed lithium-ion battery in areas that have specific requirements for the shape of the lithium-ion battery. There are great advantages. Is the lithium-ion battery better than the soft pack or the hardware? Lithium-ion battery soft packs and hard packs can only be said to have their own advantages and disadvantages. There are many soft packs of lithium polymer and high safety. The steel shell encapsulated such as 18650, most of the lithium-ion batteries, have long life. The soft bag is in its original state, and the exhaust is better; the hard bag has better heat dissipation, and the hard bag is safer. In fact, as long as the lithium-ion battery pack purchases branded products through formal channels, the branded products are tested and certified, and the quality and safety are more guaranteed. Summary: Compared with hard-pack lithium-ion batteries, soft-pack lithium-ion batteries have more or less advantages in terms of weight, capacity, and shape. However, the existing core models of soft-pack lithium-ion batteries are still relatively small. , And the cost of developing new models is also high.
