What is the difference between soft pack lithium battery and hard pack lithium battery? There are many packaging methods for lithium batteries. The more common ones are soft-packed lithium-ion batteries, hard-packed square lithium-ion batteries, soft-packed lithium-ion batteries and hard-packed lithium-ion batteries. The main difference lies in the packaging method. Batteries usually appear in small and micro digital electronic equipment, and hard-mounted lithium-ion batteries are usually used in larger electrical equipment;
Soft pack lithium ion battery:
The soft pack lithium ion battery is a simple liquid lithium ion battery with a polymer casing. In a structure that uses aluminum-plastic film packaging, the soft battery will bulge in the event of a safety hazard.
Advantages of soft-pack lithium-ion batteries:
Compared with hard lithium-ion batteries, it has the advantages of small size, light weight, high specific energy, high safety, and flexible planning. The specific advantages are as follows:
The soft pack lithium-ion battery pack is safe, unlike steel and aluminum pack batteries, it can explode.
Lightweight, the weight of the soft pack battery is 40% lighter than the steel lithium-ion battery of the same capacity, and 20% lighter than the aluminum battery.
Large capacity, the capacity of the soft-packed lithium-ion battery is 10~15% larger than that of the steel shell battery of the same size, and 5~10% larger than that of the aluminum shell battery.
The internal resistance is small, and the internal resistance of the soft pack battery is small for lithium ion batteries. Now the internal resistance core of the soft pack battery is less than 35m in China, which greatly reduces the power consumption of the battery.
Flexible planning, the shape of the soft-pack lithium-ion battery pack can be customized according to customer needs, and new battery models can be developed.
Disadvantages of soft pack lithium-ion batteries:
The main disadvantage of soft-packed lithium-ion batteries is that they have poor protection and are more susceptible to the risk of short circuit caused by foreign bodies. Because of the sealed state, soft-packed lithium-ion batteries are more prone to bloating.
Hard pack lithium ion battery:
Regarding hard-pack lithium-ion batteries, Baidu Baike does not have much introduction. I will not introduce hard-pack lithium-ion batteries in detail here. Let’s take a look at the difference between them and soft-pack lithium-ion batteries.
What is the difference between a soft pack lithium ion battery and a hard pack lithium ion battery?
Soft-pack lithium-ion batteries and hard-pack lithium-ion batteries first refers to the difference between lithium-ion battery casing materials. If you have any packaging, it is not simple, you must see the lithium-ion battery body, the battery steel shell point and the battery Volume and weight, but aluminum shell and flexible packaging is not a simple difference, but soft and flexible packaging cells are easier to deform than aluminum shells.
In terms of shape, since the battery inside the soft-packed lithium-ion battery is liquid, its shape can generally have a variety of shapes. This feature is greater than the hard-packed lithium-ion battery in terms of the specific requirements for the shape of the lithium-ion battery. Advantage.
Is the packaging of lithium iron phosphate batteries hard or soft?
In fact, the packaging characteristics of lithium-ion batteries are the same, but the packaging methods are different because of different occasions. First of all, it depends on the application. If there are strict protection requirements for the lithium-ion battery pack, it is best to use a hard case.
What is the difference between soft-pack lithium-ion batteries and hard-pack lithium-ion batteries? What is the difference between soft-pack lithium-ion batteries and hard-pack lithium-ion batteries? I believe everyone can understand through the above analysis. Energy storage power iron phosphate lithium-ion battery products have won praise from users in various industries for their stable performance and excellent technology, and they are trustworthy high-tech products in the lithium-ion battery UPS industry.
