What are the advantages of soft pack batteries?

Regarding the soft-pack battery, in terms of structure, the soft-pack battery has good safety performance, light weight, large capacity, low internal resistance, and flexible design in terms of volume. The advantages are beginning to show gradually. Its advantages and status are prominent. Generally speaking, soft-pack batteries have the following advantages: 1. Good safety: The soft-pack batteries are structured with aluminum-plastic film packaging. In the event of thermal management out of control or puncture, the soft pack will provide buffering for the cells Space, bulging and deforming, will eventually catch fire or smoke, but will not explode. 2. Light weight and high energy density: The weight of the soft pack battery is 40% lighter than the steel shell battery of the same capacity, and 20% lighter than the aluminum shell battery, so it usually has a higher energy density, and the domestic energy density has exceeded 300Wh/kg. Most battery companies in Daguan use soft pack batteries. 3. Good electrochemical performance and long life: The internal resistance of the soft pack battery is small, which can greatly reduce the self-consumption of the battery; in addition, the cycle life of the soft pack battery is longer. 4. The thickness is small and can be made thinner. Ordinary liquid lithium batteries adopt the method of customizing the shell first, and then plugging the positive and negative materials. When the thickness is below 3.6mm, there is a technical bottleneck, while lithium iron phosphate and lithium manganate batteries do not exist. For this problem, the thickness can be less than 2.5mm. 5. Large capacity Lithium iron phosphate and lithium manganate soft-packed lithium-ion batteries of the same specifications are 10-15% higher than steel-shell batteries and 5-10% higher than aluminum-shell batteries.
