The difference between cylindrical lithium battery, square lithium battery and soft pack lithium battery

Cylindrical lithium battery

On the market, we commonly lithium battery packaging mainly cylindrical, square and soft package three. Different packaging and packaging structures represent different characteristics, so what is the difference between them? Next, Hongli Lithium Manganese cylindrical battery manufacturer introduces the differences between cylindrical lithium battery, square lithium battery, soft pack lithium battery.

1, the battery appearance is different: square lithium batteries can be arbitrary size, is incomparable to cylindrical batteries.

2. The multiple characteristics are different: the welding process of cylindrical lithium battery multipole ear is limited, so the multiple characteristics are slightly weaker than that of square multipole ear plan.

3, charge and discharge service platform: use the same battery positive material, negative material, lithium battery electrolyte, so the charge and discharge service platform is theoretically the same, but the internal resistance of the square battery slightly prevails, so the charge and discharge service platform is slightly higher.

4, product quality: cylindrical lithium battery process is very perfect, pole piece public ownership of the second division defect probability is low, rewinding machine process than laminated process requires a higher life cycle and intelligent level. At this stage, the laminating process is still semi-manual. The production method is harmful to the quality of the battery.

5. Electrode welding of the pole ear: the pole ear of the cylindrical lithium battery is easier to weld than that of the square lithium battery. The square lithium battery is easy to cause dewelding and harm the quality of the battery.

6. PACK assembly: Cylindrical batteries are relatively more practical, so PACK planning is simple and the heat dissipation effect is very good. When square batteries PACK, the heat dissipation problem should be dealt with well.

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

The above is the difference between cylindrical lithium battery, square lithium battery, soft pack lithium battery, I believe you have a certain understanding, more lithium manganese battery to buy, welcome to contact Hongli lithium battery manufacturers.
