Compared with soft packs and square lithium batteries, cylindrical lithium batteries have the longest development time, with higher standardization, more mature technology, high yield and low cost.

· Mature production technology, low PACK cost, high battery product yield, and good heat dissipation performance

· Cylindrical batteries have formed a series of internationally unified standard specifications and models with mature technology and suitable for continuous mass production.

· The cylinder has a large specific surface area and a good heat dissipation effect.

· Cylindrical batteries are generally sealed batteries, and there are no maintenance problems during use.

· The battery shell has high pressure resistance, and there will be no phenomena such as square, flexible packaging battery expansion during use
