What are the advantages of soft-pack lithium batteries?

1) Good safety performance: The electrolyte of the soft-pack battery has less leakage, and the soft-pack battery will swell and crack in the event of a safety hazard, instead of exploding when the internal pressure is too high like a hard-shell battery; (2) Light weight: The weight of the soft pack battery is 40% lighter than the steel shell square battery of the same capacity, and 20% lighter than the aluminum shell square battery; (3) The battery capacity is large: the soft pack saves 20% of the volume, which is compared with the steel shell battery of the same size The capacity is 50% higher, which is 20-30% higher than the aluminum shell battery; (4) Good cycle performance: the soft-pack battery has a longer cycle life, and the attenuation of 100 cycles is 4% to 7% less than that of the aluminum shell; (5) Internal resistance Small: The internal resistance of the soft-pack battery is smaller than that of the lithium battery. The domestic minimum can be less than 35m, which greatly reduces the self-consumption of the battery; (6) Flexible design: The shape can be customized according to customer needs, and it can be made thinner, ordinary aluminum The shell can only be 4mm, and the soft package can be 0.5mm.
