What are the important advantages of soft-pack lithium batteries?

Important advantages of soft-packed lithium batteries Lithium batteries are currently divided into three major categories, namely square, cylindrical, and soft-packed; among them, the square and cylindrical shells are mainly made of aluminum alloy, stainless steel and other hard shells, while the soft-packed shells are The aluminum-plastic film is used. Compared with the square and cylindrical shells, what are the important advantages of the soft-packed lithium battery? (1) Good safety performance: The electrolyte of the soft-pack battery has less leakage, and the soft-pack battery will vent 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 of the same size The battery 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) Small resistance: The internal resistance of the soft-pack battery is smaller than that of the lithium battery, and 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 thinner and ordinary The aluminum shell can only be 4mm, and the soft package can be 0.5mm.
