Cylindrical lithium battery and square lithium battery comparison
1. Battery shape: Square size can be arbitrary design, but cylinder battery can not be compared.
2. Multiplier characteristics: the technological limitations of cylindrical battery welding multipole ears are slightly worse than those of square multipole ears.
3. Discharge platform: the lithium battery using the same anode and anode materials and electrolyte, in theory, the discharge platform should be the same, but the discharge platform in the square lithium battery is slightly higher.
4. Product quality: the manufacturing process of cylindrical battery is relatively mature, and the probability of the second cutting defect of the electrode slice is low, and the maturity and automation degree of the winding process are relatively high. The lamination process is still semi-manual, which has a negative impact on the quality of the battery.
5. Electro-ear welding: the electrode ear of the cylindrical battery is easier to weld than the square lithium battery; Square lithium battery is easy to generate soldering, which affects the battery quality.
6.PACK group: cylindrical battery is easier to use, so PACK technology is simple, good heat dissipation effect; The problem of heat dissipation should be solved when packing the square lithium battery.
7. Structure features: the chemical activity at the corners of the square lithium battery is poor, the energy density of the battery is easy to decay after long-term use, and the battery life is short.
