1) Good safety performance: The electrolyte of the soft pack battery is less leaking, and the ordinary aluminum shell can only be 4mm. The capacity is 50% higher than that of steel shell batteries of the same size. It can be made thinner, and the soft package can be 0.5mm. The smallest domestic battery can be less than 35m, which is 20% lighter than aluminum shell prismatic batteries; (3) Large battery capacity: the soft pack saves 20% of the volume, and the 100-cycle attenuation is 4% to 7% less than that of the aluminum shell; (5) Internal resistance Small: The internal resistance of the soft pack battery is lower than that of the lithium ion battery. Unlike hard-shell batteries, which may explode if the internal pressure is too high; (2) Lightweight: The weight of soft-pack batteries is 40% lighter than steel-shell prismatic batteries of the same capacity, and 20-30% higher than aluminum-shell batteries; (4) Recycling Good performance: the cycle life of the soft-pack battery is longer, which greatly reduces the self-consumption of the battery; (6) Flexible design: the shape can be customized according to customer needs, and the soft-pack battery will burst in case of safety hazards. open.
