Analyze the differences between cylindrical lithium battery brand manufacturers, square lithium battery wholesale manufacturers, and soft pack lithium battery manufacturers.
At present, the popular packaging for lithium battery manufacturers mainly includes cylindrical, square, and soft packs. Different packaging and packaging structures represent different characteristics, so what are the differences between them? This article BATTSYS will introduce the differences between cylindrical lithium battery brand manufacturers, square lithium battery wholesale manufacturers, and soft pack lithium battery manufacturers.
1. The appearance of batteries is different: Wholesale manufacturers of square lithium batteries can choose any size, which cannot be compared to cylindrical batteries.
2. The multiple characteristics are different: the welding process of cylindrical lithium battery manufacturers' multipole ears is limited, so the multiple characteristics are slightly weaker than the square multipole ear plan scheme.
3. Charging and discharging service platform: Using the same battery positive electrode material, negative electrode material, and electrolyte from lithium battery manufacturers, the charging and discharging service platform is theoretically the same, except that the internal resistance of square batteries slightly dominates, so the charging and discharging service platform is slightly higher.
4. Product quality: The cylindrical lithium battery brand manufacturer has a very complete process, and the probability of the disadvantage of secondary segmentation in the public ownership of the polarizer is low. The rewinding machine process requires a higher life cycle and intelligence level than the laminating process. At this stage, the lamination process is still semi manual. The production method has a negative impact on the quality of the battery.
5. Electrode welding of
cylindrical lithium battery manufacturers' electrode ears are easier to weld than those of square lithium battery wholesale manufacturers, and square lithium battery wholesale manufacturers are prone to causing delamination and endangering battery quality.
6. PACK assembly: Cylindrical batteries have more practical characteristics due to their relative nature, so the PACK plan is simple and the heat dissipation effect is very good. When packing square batteries, it is necessary to handle the heat dissipation problem well.
7. Structural characteristics: The organic chemical energy at the edges of square batteries is weak, and the long-term application of batteries significantly reduces their characteristics.
In summary, whether it is cylindrical batteries, square batteries, or soft pack batteries, the current trend of rapid development is often due to their good application in their respective main purposes.
