What are the advantages and disadvantages of cylindrical lithium battery packs?

Although in the first half of this year, the number of cylindrical lithium battery assembly machines is not comparable to that of square lithium battery packs, with the development of some foreign electric vehicles, cylindrical lithium battery packs have also been advanced. Let's talk about some of the advantages and disadvantages of cylindrical lithium battery packs. The advantages of cylindrical lithium battery packs: 1. As mentioned above, the monomer has good consistency; 2. The mechanical properties of the monomer itself are good. Compared with square and soft-pack batteries, the closed cylinder can be of approximate size. Obtain the highest bending strength; Third, the technology is mature and the cost is low, but at the same time, the space for cost optimization has been consumed almost; the disadvantages of cylindrical lithium battery packs: 1. In the context of electric vehicles, the cylindrical battery system The number of bodies is very large, which greatly increases the complexity of the battery system. Regardless of the organization or the management system, the cost of the cylindrical battery at the system level is relatively high for the other two types of batteries. Second, in the uneven temperature environment, a large amount of electricity The probability of alienation of core characteristics increases; Statement: Some pictures and content of articles published on this site are from the Internet.
