1. Battery shape: Square lithium-ion batteries can be of any size, so they cannot be compared to cylindrical batteries.

2. Ratio characteristics: Due to the process limitations of welding multipole ears in cylindrical lithium-ion batteries, the ratio characteristics are slightly worse than those of the square multipole ear method

3. Discharge platform: The same positive electrode material, negative electrode material, and electrolyte are used, so theoretically the discharge platform is the same. However, the internal resistance of square batteries is slightly superior, so the discharge platform is slightly higher.

4. Product quality: The cylindrical lithium-ion battery process is very mature, and the probability of secondary cutting defects in the electrode is low. In addition, the winding process is more mature and automated than the stacking process, and the stacking process is still using semi manual methods. Therefore, there are adverse effects on the quality of the battery.
