The difference between lithium battery and soft lithium battery

The advantages of the soft-pack lithium battery are good safety performance, light weight, large capacity, small internal resistance and flexible design.

The soft-pack lithium battery is simply a liquid lithium-ion battery with a polymer shell. The structure is packaged in aluminum plastic film, and in the case of a safety hazard, the soft pack battery will only burst at most.

The reason why the soft-pack lithium battery has the above advantages is:

1. The soft-packed lithium battery does not explode like the steel-shell aluminum-shell battery, so the safety performance is good.

2, the weight of the soft lithium battery is 40% lighter than the equivalent capacity of the steel shell lithium battery, 20% lighter than the aluminum shell battery, so the weight is light.

3. The capacity of the soft-packed lithium battery is 10-15% higher than that of the steel shell of the same size, which is 5-10% higher than that of the aluminum shell battery, so the capacity is large.

4. The internal resistance of the soft-packed lithium battery is smaller than that of the lithium battery. At present, the internal resistance of the domestic soft-pack battery core can be as low as 35mΩ, which greatly reduces the self-consumption of the battery.

5, the shape of the soft lithium battery can be customized according to customer needs, the development of new battery models.

Mainly refers to the material of the lithium battery case. If there is packaging on the outside, it is not easy to see. The battery body must be seen. The weight of the steel case battery will be more important than the same volume of the battery, but the aluminum case and the flexible package are not easy. Differentiate, but the flexible packaging battery will be softer than the aluminum battery, and it will be easily deformed by hand.

The soft-pack lithium battery is simply a liquid lithium-ion battery with a polymer shell. The structure is packaged in aluminum plastic film, and in the case of a safety hazard, the soft pack battery will only burst at most.

1. Good safety performance

Soft pack batteries, unlike steel shell aluminum shell batteries, can explode.

2. Light weight

The weight of the soft pack battery is 40% lighter than the equivalent capacity of the steel shell lithium battery, which is 20% lighter than the aluminum shell battery.

3. Large capacity

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

4. Small internal resistance

The internal resistance of the soft pack battery is smaller than that of the lithium battery. At present, the internal resistance of the domestic soft pack battery core can be as low as 35 mΩ, which greatly reduces the self-consumption of the battery.

5. Flexible design

The shape of the soft pack battery can be customized according to the customer's needs, and a new battery model can be developed.

The existing soft pack battery core models are few and cannot meet the market demand;

Developing new models is costly.

1. Do not expose the battery to the sun or throw it into the fire;

2. The battery cannot be reversed when charging the battery;

3. Avoid short circuit batteries;

4. Avoid excessive physical shock and shock cells;

5. Cannot disassemble or deform the battery;

6. Cannot immerse the battery in water;

7. Cannot mix other manufacturers, types, models of batteries

8. Children are not allowed to contact the battery

9. The battery must be charged under the right conditions

10. Never use a faulty charger to charge the battery.

11. The battery cannot charge more than 24H.
