Soft case Li-ion batteries are 40% and 20% lighter than steel and aluminum case Li-ion batteries. In terms of weight, soft-loaded lithium-ion batteries are much lighter than hard-loaded lithium-ion batteries, but the important weight ratio still depends on the weight of the box.

low capacity
Soft pack lithium-ion batteries are 10% to 15% higher than steel and aluminum batteries, and 5% to 10% higher than steel and aluminum batteries. Although the capacity of soft-pack lithium-ion batteries is not much higher than that of hard-pack lithium-ion batteries, there is still a certain gap between the two. In areas with higher capacity requirements, the application of soft-pack lithium-ion batteries is still higher than that of hard-pack lithium-ion batteries.

low shape
Because the internal battery of the soft lithium-ion battery is liquid, its shape can generally have various shapes, which has a great advantage over the hard lithium-ion battery in the field that has specific requirements for the shape of the lithium-ion battery.

Lithium-ion battery inverted soft pack or better hardware?
Lithium-ion battery soft pack and hard pack can only be said to have their own advantages and disadvantages, soft pack lithium polymer, high safety, ladle such as 18650, most lithium-ion batteries, long life. Soft bags are raw and vent better; hard bags are better for cooling. Hard bags are safer. In fact, as long as the brand products of lithium-ion battery packs are purchased through formal channels, the brand products are all tested and certified, and the quality and safety are more guaranteed.

Conclusion: Compared with hard Li-ion batteries, soft Li-ion batteries have more or less advantages in terms of weight, capacity, and shape. However, there are relatively few core models of existing soft-package lithium-ion batteries, and the cost of developing new models is also high. Therefore, flexible packaged lithium-ion batteries can still meet less market demand.
