Comparative analysis of technical characteristics of various lithium batteries
1. Battery shape: Square lithium batteries can be any size, so it is not comparable to cylindrical batteries.
2. Magnification characteristics: The process limitation of cylindrical lithium battery welding multipole lug, so the magnification characteristics are slightly poor
In square multipole lug scheme
3. Discharge platform: the same positive electrode material, negative electrode material, electrolyte is theoretically discharged
The platform is consistent, but the internal resistance of the square battery is slightly dominant, so the discharge platform is slightly higher.
4. Product quality: The cylindrical lithium battery process is very mature, and the probability of public secondary slitting defects is low.
And the winding process is more mature and automated than the lamination process is still in use
Semi-manual method, so there is a negative impact on the quality of the battery.
5. Pole ear welding: cylindrical lithium battery pole ear is easier to weld than square lithium battery, and square battery is easy to produce
Virtual welding affects battery quality.
6.PACK group: The round battery is relatively easy to use, so the PACK program is simple and loose
The thermal effect is good, and the problem of heat dissipation should be solved when the square battery PACK is packed.
7. Structural characteristics: The chemical activity at the corners of the square battery is poor, and the long-term use of the battery performance is reduced
More obvious.
