Advantages and development prospects of soft-pack lithium-ion batteries

Soft-packed lithium-ion battery packs, unlike steel shell aluminum shell batteries, will explode. The soft pack battery is 40% lighter than a steel shell lithium battery of the same capacity and 20% lighter than an aluminum shell battery. The capacity of the soft-packed lithium-ion battery pack is 10-15% higher than that of the steel shell battery of the same specification and 5-10% higher than that of the aluminum shell battery. The internal resistance of soft-pack batteries is smaller than that of lithium-ion batteries. Now, the minimum internal resistance of domestic soft-pack battery cells can be less than 35m, which greatly reduces the self-consumption of the battery. The shape of the soft pack battery can be customized according to the needs of customers, and new battery cell models can be developed. Soft-pack batteries are actually batteries that use aluminum-plastic packaging film as packaging materials. Relatively speaking, lithium-ion battery packaging is divided into two categories, one is soft-packed batteries, and the other is metal shell batteries. Metal shell batteries also include steel shells and aluminum shells, etc. In recent years, some batteries that use plastic shells due to special needs can also be classified as this type. The development prospects of soft-packed lithium-ion battery packs: Compared with hard-shell batteries (square and cylindrical), soft-packed lithium-ion battery packs have the characteristics of sensitive design, light weight, small internal resistance, not easy to explode, many cycles, and high energy density. It can increase the energy density of power lithium batteries on the existing technical level, and further narrow the gap with fuel vehicles in terms of cruising range. There is little difference in the internal components of lithium-ion battery packs. The core difference is that cylindrical and square batteries mainly use metal materials as the shell, while soft-pack lithium-ion batteries use aluminum-plastic film as the packaging shell. The difference between the soft pack and the hard pack of lithium-ion batteries mainly refers to the material of the lithium-ion battery casing. If there is a packaging outside, it is not easy to see it, and the battery body must be seen. Flexible packaging lithium-ion batteries with obvious advantages have become the first choice, and there is huge room for market development.
