Important advantages of soft pack lithium batteries

(1) Good safety performance: The electrolyte leakage of the soft-shell battery is less, and the soft-shell battery will burst when there is a safety hazard, instead of exploding when the battery is pressed like a hard-shell battery; (2) ) Light weight: The weight of the soft pack battery is 40% lighter than the square steel battery of the same capacity and 20% lighter than the square aluminum battery; (3) The battery capacity is large: the soft pack can save 20% of the volume, which is 50% higher than the steel shell battery of the same size. %, 20-30% higher than the aluminum shell battery; (4) Good cycle performance: the soft pack battery has a longer cycle life, and the 100-cycle attenuation is 4%~7% lower than that of the aluminum shell; (5) The internal resistance is small and soft The internal resistance of the battery pack is a lithium battery with a low internal resistance of less than 35m, which greatly reduces the power consumption of the battery; (6) The design is flexible: the shape can be customized according to customer requirements, and it can be made thinner, which can only be achieved by ordinary aluminum shells. 4mm, the soft bag can only reach 0.5mm. In terms of performance, soft-pack batteries have more comprehensive advantages, and the future application prospects are broad: (1) Soft-pack batteries are more suitable for portable applications with high space or thickness, such as 3C consumer electronics; (2) prismatic batteries have high single capacity , But the weight is large, and the soft pack battery has obvious advantages in energy density. At present, single cells are also developing in the direction of large-capacity, high-multiplier, which will better meet the needs of mobile power in fields such as new energy vehicles.
