Soft -pack lithium -ion battery is just a liquid lithium -ion battery cover. In the structure, the aluminum -plastic film is packaged, and the soft bag lithium -ion battery packs will only be splined and cracks when the safety hazard occurs.

advantage

Soft pack lithium -ion battery packs have good safety performance, unlike the steel shell aluminum shell cells explosion.

Light and lithium batteries with a light weight, the weight of the soft bag battery is 40%lighter than the same capacity, and 20%lighter than the aluminum shell battery.

The capacity is large, and the capacity of the steel shell battery of the soft bag lithium -ion battery is 10-15%higher than the capacity of the same size, 5-10%higher than the aluminum shell battery.

The internal resistance is small, and the internal resistance of the soft bag battery is smaller than that of lithium -ion batteries. At present, the internal resistance of the domestic soft -packed battery core can be less than 35m, which greatly reduces the self -consumption of the battery.

The design is flexible. The shape of the soft -pack lithium -ion battery pack can be customized according to the needs of the customer to develop a new batteries.

shortcoming

The existing soft bag battery core has fewer models, which cannot meet market demand, and the development of new models is high.

Hard pack lithium -ion battery

The hard -packed lithium -ion battery is subdivided into cylinders and squares. Different from the soft bag lithium -ion batteries is that the external packaging shell is a metal shell, so the same volume of hard bag lithium -ion batteries is much heavier than the soft bag lithium -ion battery.
