Compared with soft packs and square batteries, cylindrical batteries have the longest development time, the highest degree of standardization of production process equipment, the most mature technology, the highest yield rate of production, and the lowest production cost. 1. The production process is mature, the equipment is highly mechanized, the battery product yield is high during the production process, and the process production cost is lower than that of soft packs and squares. 2. The assembly cost of the PACK is low, the surface area of the cylinder is large, and the battery pack is assembled into a battery pack, and the heat dissipation performance of the battery pack is good. 3. The battery shell has high pressure resistance, and there will be no phenomena such as square, flexible packaging battery expansion during use and transportation. 4. The steel shell battery has a hard outer shell, which is less prone to be pierced by sharp objects than a soft pack battery, which may cause safety problems. |
