      Advantages of cylindrical cells

  1) As mentioned above, the consistency of the monomer is better;

  2) The mechanical properties of the monomer itself are good. Compared with the square and pouch batteries, the closed cylinder can obtain the highest bending strength under the approximate size;

  3) The technology is mature and the cost is low, but at the same time, the space for cost optimization has been almost consumed;

  4) The energy of the monomer is small, and the form is easy to control when an accident occurs, but this is also becoming the reason for its replacement (how about that popular saying, what makes you will also destroy you, and what cannot kill you will also make you You are strong, so it makes sense)

  Advantages and disadvantages of cylindrical cells

  1) In the context of electric vehicles, the number of cylindrical cells in the battery system is very large, which greatly increases the complexity of the battery system. Regardless of the mechanism or the management system, compared with the other two types of batteries, the cost of the cylindrical battery at the system level High;

  2) Under the condition of uneven temperature environment, the probability of a large number of cell characteristics dissimilation increases. Of course, the reason why Tesla chose 18650 at the beginning of the design is believed to be a helpless choice, because 10 years ago, it was possible to mass-produce Qualified power batteries, only cylindrical batteries. The safety and thermal management requirements of the battery are, on the contrary, the driving force for the development of its powerful electronic control system.

  3) There is very little room for improvement in energy density. According to the news in 2016, Chaowei achieved a single capacity of 4050mAh and a battery specific energy of 306Wh/kg. Since then, no higher record has been seen. In a given space, there are only dead materials, which is recognized as a difficult road.
