What is the difference between soft-pack lithium-ion batteries and hard-pack lithium-ion batteries?

Compared with the steel shell lithium ion battery and aluminum shell lithium ion battery of the same capacity, the soft pack lithium ion battery is 40% lighter and 20% lighter. 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 soft-packed lithium-ion batteries is 10% to 15% and 5% to 10% higher than that of steel shell batteries and aluminum shell batteries of the same size. Although in terms of capacity, soft-pack lithium-ion batteries are not much higher than hard-pack lithium-ion batteries, but there is a certain gap between the two. Regarding the scale 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 various shapes under normal circumstances. This feature is better than that of the hard-packed lithium-ion battery in terms of specific requirements for the shape of the lithium-ion battery. There are great advantages. Is the lithium-ion battery good for a soft pack or good for 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 security. The steel shell encapsulated such as 18650, most of the lithium-ion batteries, have long life. The soft case is in its original state, and the exhaust is better; the hard case has better heat dissipation, and the hard case is more peaceful. In fact, as long as the lithium-ion battery pack purchases brand products through formal channels, the brand products are all tested and certified, and the quality and safety are more and more guaranteed. Summary: Compared with hard-packed lithium-ion batteries, soft-packed lithium-ion batteries have more or less advantages in terms of weight, capacity, and shape. However, the existing core models of soft-packed lithium-ion batteries are still relatively small. Yes, and the cost of developing new models is also high, so the market demand for soft-pack lithium-ion batteries is still less.
