What are the benefits of increasing the battery from 18650 to 21700?

The size is increased from 18650 to 21700, and the benefits are as follows: 1) When the energy density is appropriately increased, conventional materials can be selected, the battery performance is stable and cost-effective; 2) The multi-electrode mechanism can be appropriately designed to reduce internal resistance; 3) The same Under energy density, you can choose fast charging characteristic graphite to improve fast charging performance; 4) Appropriately add diameter and height to obtain more effective volume. 5) The capacity of the battery cell is increased, the proportion of auxiliary components is reduced, and the pack cost is reduced. In the new national standard 'GB/T34013-2017 Electric Vehicle Power Battery Product Specifications and Dimensions' issued by the Ministry of Industry and Information Technology, only 18650 and 32650 in the original draft for comments have been revised into 4 specifications including 21700, which are also counted as A major benefit of 21700.
