Which is better between cylindrical lithium-ion batteries and soft pack lithium-ion batteries.

Which is better between cylindrical lithium-ion batteries and soft pack lithium-ion batteries：

1. The safety performance of the soft pack battery is good. The structure of the soft pack battery is packaged with aluminum plastic film, and when safety issues occur, the soft pack battery will generally burst and crack, unlike the steel shell or aluminum shell battery cells that can explode; In terms of safety performance, it is superior to cylindrical lithium-ion batteries.

2. The weight of soft pack batteries is relatively light, with 40% lighter than steel shell lithium-ion batteries of the same capacity and 20% lighter than cylindrical aluminum shell lithium-ion batteries; Low internal resistance, the internal resistance of soft pack batteries is smaller than that of lithium-ion batteries, which can greatly reduce the battery's self consumption;

3. The cycling performance of the soft pack battery is good, and the cycling life of the soft pack battery is longer. The attenuation after 100 cycles is 4% to 7% less than that of the cylindrical aluminum shell battery;

4. The design of the soft pack battery is relatively flexible, with a variable shape and can be thinner. It can be customized according to customer needs and new battery cell models can be developed. However, cylindrical lithium-ion batteries do not meet this condition.

5. Compared to cylindrical lithium-ion batteries, the disadvantages of soft pack batteries are poor consistency, high cost, and easy leakage. The high cost can be solved through large-scale production, while leakage can be solved by improving the quality of aluminum plastic film.
