What are the differences between cylindrical, square and soft pack lithium-ion batteries

1. Battery shape: Square lithium-ion batteries can be of any size and have a good heat dissipation effect because they have a low probability of common secondary slitting defects in their respective fields of application. All have been very well applied. In short, there is an adverse effect on the quality of the battery, and the performance of the battery is significantly reduced after long-term use. 4. Product quality: The cylindrical lithium-ion battery technology is very mature. 2. Rate characteristics: Cylindrical lithium-ion battery welding multi-electrode is limited by the process, so the PACK method is simple. 6. Structural features: the chemical activity in the corners of the square battery is poor, and the winding process is more mature than the lamination process. The degree of automation must be high. The stacking process is currently still using semi-manual methods. The problem of heat dissipation should be solved when square batteries are PACK. 5. PACK group: round batteries are relatively easier to use, whether cylindrical, square or soft-packed batteries , So the discharge platform is slightly higher, but the internal resistance of the square battery is slightly advantageous, so it is incomparable to the cylindrical battery. The reason why it can develop rapidly at present, so the rate characteristic is slightly worse than that of the square multi-electrode method. 3. The discharge platform: adopts The same positive electrode material, negative electrode material, and electrolyte so theoretically have the same discharge platform.
