What are the advantages and disadvantages of soft-pack lithium batteries?

Soft-pack lithium batteries are simply liquid lithium-ion batteries coated in a polymer shell. In the structure of aluminum plastic film packaging, in the case of potential safety hazards, the soft-pack battery will only blow up and crack at most.

The advantages of soft-pack battery:

1. Good safety performance

A soft-pack battery does not explode like a steel or aluminum core.

2. Light weight

The soft-pack battery is 40% lighter than lithium battery with the same capacity and 20% lighter than aluminum battery with the same capacity.

3. Large capacity

The capacity of soft-pack battery is 10 ~ 15% higher than that of steel shell battery of the same size, and 5 ~ 10% higher than that of aluminum shell battery.

4. Small resistance

Soft package of battery internal resistance is small lithium-ion batteries, the current domestic soft package can be done in the internal resistance of battery core minimum below 35mΩ, greatly reduced since the power consumption of the battery.

5. Design flexible

The shape of soft-pack battery can be customized according to the needs of customers to develop new cell models.

The disadvantages of soft-pack battery:

There are few types of soft-pack battery cells, which cannot meet the market demand.

Developing new models is costly.
