It has mature automatic production process, high output, good consistency. Such small battery has large heat dissipation area than prismatic, but a bit complex to form system and comparatively low reliability after system composition.
The main characteristics of prismatic lithium battery: the shell is made of aluminium alloy, stainless steel and other materials, with high structural strength, good mechanical load-bearing capacity. But the heavy shell, which leads to certain restrictions on the energy density of the battery pack. The processing is complex, the product yield is low, and the consistency is relatively poor.
Some factory also calls this soft battery cell or aluminium-plastic membrane battery. The main characteristics of it: relatively good safety performance, not the easy explosion, high energy density, good ductility. But high cost, relatively poor mechanical load-bearing capacity, easy to damage and leakage.
