What are the advantages of soft pack lithium batteries compared to other lithium batteries?

Soft-pack lithium batteries Ordinary power lithium-ion batteries are generally divided into two types: soft packaging and hard packaging according to their packaging. In order to meet the diverse needs of shopping malls, lithium batteries with different packaging structures also have their own advantages and disadvantages. At present, the market share of soft lithium batteries continues to increase, and lithium battery products are also rapidly developing and changing. The term soft pack in the soft pack lithium battery actually refers to the polymer shell on the top of the lithium battery, which is mainly packaged with aluminum-plastic film. Soft-pack lithium batteries are actually another name for polymer lithium batteries. Soft-pack lithium batteries have the following advantages: 1. Good safety performance: Soft-pack batteries, unlike steel shells and aluminum shells that attack explosions, usually attack safety. When there is a hidden danger, the shell will only explode at best. 2. Small size, light weight, high energy: In terms of weight, the soft pack battery is 40% lighter than the steel shell lithium battery of the same capacity, and 20% lighter than the aluminum shell battery. In terms of capacity, compared with steel batteries of the same specification and scale, the capacity of soft lithium batteries is 10-15% higher, and that of aluminum batteries is 5-10% higher. 3. Small internal resistance: As we all know, the lithium battery itself attacks the unpreventable self-discharge reaction, and the greater the internal resistance, the stronger the self-discharge. Relatively speaking, the internal resistance of the soft lithium battery is small, which greatly reduces the self-consumption of the battery. 4. Flexible planning: The shape of the soft pack battery can be determined according to the specific needs of the market. Customized planning can be made according to the detailed size of the battery box. It is known that the important application categories of soft pack lithium batteries can be subdivided into 3C, power and energy storage. The application of soft pack batteries is first of all 3C category, in recent years, especially in notebook computers, mobile phone batteries and other consumables accounted for more than 60%. At the same time, with the continuous development of new energy vehicles, the penetration rate of the lithium-ion market is also increasing. The energy storage mall is an emerging category of lithium battery applications, and there are fewer soft pack applications in a short period of time. In the future, as the cost of flexible packaging decreases, this field also has great potential for growth. In addition, the biggest difference between soft-pack lithium batteries and other batteries is the soft-pack material, which uses aluminum-plastic composite film, which is also the most critical and technically difficult material for soft-pack lithium batteries. At present, there are fewer soft pack unit models on the market, and the development cost is generally higher. Industry insiders pointed out that the reason for the continuous expansion of the market share of soft pack batteries is to follow the maturity of technology. The most important thing is that the advantages of soft pack batteries are safety, specific energy, cycle life and agile plans are gradually highlighted, especially the 3 yuan soft pack battery The energy density has greatly advanced.
