What are the differences between cylindrical batteries, square batteries, and soft-packed lithium batteries?

Comparison of cylindrical, square and soft-packed lithium batteries 1. Battery shape: square lithium batteries can be of any size, so they cannot be compared to cylindrical batteries. 2. Rate characteristics: Cylindrical lithium battery welding multi-electrode is limited by the process, so the rate characteristics are slightly worse than the square multi-electrode method. 3. Discharge platform: The same cathode material, anode material, and electrolyte are used, so theoretically the discharge platform is The same, but the internal resistance of the square battery has a slight advantage, so the discharge platform is slightly higher. 4. Product quality: Cylindrical lithium battery technology is very mature, the probability of common secondary slitting defects of the pole piece is low, and the winding process is more mature and automated than the lamination process. The lamination process is currently still using semi-manual methods. Therefore, there is an adverse effect on the quality of the battery. 5. Welding of tabs: The tabs of cylindrical lithium batteries are easier to weld than square lithium batteries, and square batteries are prone to false welding that affects battery quality. 6. PACK into groups: round batteries are relatively easier to use, so the PACK method is simple, and the heat dissipation effect is good. When the square batteries are PACK, the heat dissipation problem must be solved. Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
