Advantages of 21700 lithium battery：
1. The capacity of 21700 lithium battery cells is increased by 35%.
2. The energy density of the 2.21700 lithium battery system is increased by about 20%.
3. The cost of the system is expected to drop by about 9%.
4. The weight of the system is expected to drop by about 10%. The overall volume of the 21700 lithium battery is larger than that of the 18650 lithium battery. As the monomer capacity increases, the energy density of the monomer is higher, so the number of battery monomers required under the same energy can be reduced by about 1/3.
5. The energy density of the battery is increased by more than 20%, and the energy density of the 21700 battery is better than that of the 18650 battery.
