A cylindrical cell that is 46mm in diameter and 80mm high. Capacity tests : 26.5Ah (estimate based on 21700 5Ah volumetric energy density) and this fits with capacity of the Model Y pack that uses this cell. The Laboratory for Energy Storage and Conversion carried out the testing and data analysis of the two 4680 cells reported in this article.
Fig 2: 4680 vs. 2170 cell Tesla battery pack. More energy storage in the same battery pack space. Credits: MunroLive.com. 2170 cell is 5000 mAh and Munro’s analysis says the 4680 new Tesla cell will be around ~9000 mAH.
1. Energy Density: The 4680 battery boasts a significantly higher energy density than conventional cylindrical cells. This means it can store more energy per unit volume, enabling electric vehicles to achieve longer ranges on a single charge and enhancing the efficiency of energy storage systems.
The Tesla 4680 cell has intrigued ever since it was announced. A cylindrical cell that is 46mm in diameter and 80mm high. Capacity tests : 26.5Ah (estimate based on 21700 5Ah volumetric energy density) and this fits with capacity of the Model Y pack that uses this cell.
The visionary electric vehicle and energy company Tesla introduced the 4680 battery cell during its Battery Day event in 2020. Tesla's CEO, Elon Musk, highlighted its potential to revolutionize electric vehicles (EVs) and grid energy storage. 1. Energy Density:
Another cost and time savings with the usage of new 4680 cells will come from reducing the number of connections between the cells. With a significant number of fewer cells, the new battery pack will require around 1,800 connections compared to the current packs with ~8,800 wire tabs.
