Industry-leading Efficiency
At present, in order to increase the energy density of the battery system and reduce the number of battery cells, thereby reducing the cost, whether it is prismatic, cylindrical or pouch batteries, there has been a development trend of increasing the size of single cells. It is more obvious that there is a phenomenon of upgrading from 18650 to 21700/26650 in the field of cylindrical batteries.
Advantages
Capacity Improvement >
The battery cell capacity is increased by 35%. After switching from the 18650 model to the 21700 model, the battery cell capacity can reach 3 to 4.8Ah, which is a substantial increase of 35%.
Energy Density Increase >
The energy density of the battery system increases by about 20%. The energy density of the 18650 battery system used in the early days was about 250Wh/kg, while the energy density of the 21700 battery system was around 300Wh/kg.
Weight Reduction >
The weight of the system is expected to drop by about 10%. The overall volume of 21700 is greater than 18650. 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.
