The above mentioned lithium battery can be divided into cylindrical lithium ion battery, square lithium ion battery and polymer soft pack lithium ion battery. What is the difference between these three types of lithium ion battery

The large diameter of the cylindrical lithium-ion battery limits the thickness of the terminal consumer electronic products. The design of the square lithium-ion battery is relatively fixed. Compared with the polymer soft pack lithium-ion battery, it is difficult to achieve thinness.

Polymer soft pack lithium-ion battery adopts aluminum plastic film as packaging material, which has lighter weight and higher safety.The shape design is more flexible, the battery shape can be customized according to customer needs;High energy density, under the condition of maintaining a certain battery capacity, the volume of polymer soft pack lithium ion battery is smaller;And its cycle life is long, good heat dissipation, can better meet the consumer electronic products for thinness, safety, energy density, size change and other aspects of the needs.

Therefore, consumer lithium-ion batteries have undergone a transition from cylindrical and square batteries to polymer soft packs.

In the field of power batteries, compared with cylindrical and square batteries using metal materials as the shell, soft pack batteries have the advantages of light weight, good safety performance, flexible appearance design and so on.

As electronics continue to evolve and come in all shapes and sizes, the advantages of polymer soft-pack lithium-ion batteries are significantly more flexible than other products.

These are the differences between the three lithium-ion batteries. If there are more unclear questions, please stay tuned.
