The weight of the pouch battery is 40% lighter than the steel-cased lithium battery of the same capacity, and 20% lighter than the aluminum-cased battery.
The capacity of the soft-pack lithium-ion battery pack is 10-15% higher than that of steel-cased batteries of the same specification and size, and 5-10% higher than that of aluminum-cased batteries.
The internal resistance of soft-pack batteries is smaller than that of lithium-ion batteries. At present, the minimum internal resistance of domestic soft-pack battery cells can be less than 35m, which greatly reduces the self-consumption of batteries.
The shape of the soft pack lithium-ion battery pack can be customized according to the needs of customers, and new cell models can be developed.
