At this stage, there are three key types of popular lithium battery packaging, namely cylindrical, square and soft packs. Different packaging structures represent different characteristics, so what are the differences between them? Shenzhen Topbond battery for everyone introduce:

1. Battery appearance: The square lithium battery can be arbitrarily sized, so it is incomparable to the cylindrical battery.

2. Multiple characteristics: The process of welding multi-pole lugs for cylindrical lithium batteries is limited, so the multiple characteristics are slightly weaker than that of the square multi-pole lug scheme.

3. Charge and discharge service platform: The same battery positive electrode material, negative electrode material, and lithium battery electrolyte are used, so the charge and discharge service platform is theoretically the same, but the internal resistance of the square battery is slightly higher, so the charge and discharge service platform is slightly higher.

4. Product quality: The Cylindrical LFP cell technology is very perfect, the probability of secondary segmentation of the public ownership of the pole piece is low, and the rewinding machine process requires a higher life cycle and intelligent level than the lamination process. The lamination process is still semi-manual at this stage. The production method, so there is a bad hazard for the quality of the battery.

5. Electrode welding of tabs: The tabs of cylindrical lithium batteries are easier to weld than square lithium batteries.

6. PACK block: The ring-shaped battery is relatively more practical, so the PACK plan is simple and the heat removal effect is very good.

7. Structural characteristics: The organic chemical energy at the edge of the square battery is weak, and the battery characteristics are significantly reduced in long-term applications.

All in all, whether cylindrical, square or soft pack batteries, they can often develop rapidly at this stage, because they have been well used in the main uses that they are good at.
