Studies have shown that the 21700 4500mah battery produces more heat during high-current charging and discharging, so the polarization of the battery is correspondingly smaller. At the same time, the energy density can be increased by about 6% due to the decrease in the proportion of inactive materials such as the casing.
In the case of appropriately increasing the energy density, conventional materials with stable performance and high cost performance can be selected.
The multi-electrode mechanism can be appropriately designed to reduce the internal resistance. Under the same energy density, the fast charging characteristic graphite can be selected to improve the fast charging performance.
Appropriately increasing the diameter and height can get a more effective volume. The capacity of the single cell increases, the proportion of auxiliary components decreases, and the battery component cost decreases.
