1. Good safety performance: Because the soft-pack lithium battery is packed with aluminum-plastic film, the soft-pack lithium battery will not explode in the case of safety risks, but only blow up or crack.

2. Lightweight type: the weight of soft pack lithium battery is about 20% lighter than that of aluminum shell battery.

3. Large battery capacity: Compared with aluminum shell battery of the same specification, the capacity of soft pack lithium battery is about 5~10% higher than that of aluminum shell battery

4. Small internal resistance: At present, the internal resistance of soft-pack lithium battery has reached the minimum below 5mΩ, which greatly reduces the battery power consumption.

5, good cycle performance: soft pack battery cycle life is longer, 100 cycle attenuation is 4% ~ 7% less than aluminum shell.

6, the design is flexible: the shape of the soft pack lithium battery can be designed according to the requirements of customers, to meet the needs of different customers, can be made into a variety of irregular soft pack lithium battery, ordinary aluminum shell can only do 4mm, soft bag can do 0.5mm.

7, soft pack lithium battery is more suitable for portable, high space or thickness requirements of the application field, such as 3C consumer electronics.
