Soft pack lithium battery
The key materials used in soft pack lithium batteries - positive electrode materials, negative electrode materials and diaphragms - and traditional steel
The difference between shell and aluminum shell lithium battery is not big, the biggest difference is the flexible packaging material (aluminum plastic
Composite film), which is the most critical and technically difficult material in soft pack lithium batteries. Flexible packaging material
It is usually divided into three layers, that is, the external barrier layer (usually the outer protective layer composed of nylon BOPA or PET),
The anti-penetration layer (intermediate layer of aluminum foil) and the inner layer (multi-functional high barrier layer).
The packaging materials and structure of the soft-pack battery make it have a series of advantages, electric knowledge home public number summary
For example, the safety performance is good, and the soft pack battery is structurally packaged with aluminum-plastic film, which causes safety problems
When the problem, the soft pack battery will generally blow open, rather than explode like the steel shell or aluminum shell cell;
Light weight, soft pack battery weight is 40% lighter than the same capacity of steel shell lithium battery, lighter than aluminum shell lithium battery
20%; The internal resistance of the soft pack battery is smaller than that of the lithium battery, which can greatly reduce the power consumption of the battery;
The cycle performance is good, the cycle life of the soft pack battery is longer, and the attenuation of 100 cycles is less than that of the aluminum shell
4%-7%; Flexible design, shape variable arbitrary shape, can be thinner, can be determined according to customer needs
To develop new cell models. The disadvantage of soft-pack batteries is poor consistency and high cost.
Prone to leakage. The high cost can be solved by large-scale production, and the leakage can be improved by aluminum plastic
Membrane quality to solve.
