Cylindrical Cell Comparison 4680 vs 21700 vs 18650

In this Article, we will compare different Cylindrical Cell Sizes used in electric Vehicles. 4680 vs 21700 vs 18650. if you are interested to learn about Cells, different Cell Formats, Cell Manufacturers, Battery Cell Manufacturing process please click the links.

The Table is live and I will edit along with Nigel as we get more data and information on the particular cell Size. If you want to read in detailed analysis for various Vehicle model please go to Benchmarking section.

Tesla particularly uses Cylindrical cells in their Electric Vehicles. As per recent announcement Tesla is moving to 4680 from 21700 and the older 18650. Tesla various vehicle Models: Model S, Model Y, Model 3, Model X, Roadster. Read about Tesla 4680 cell design.

Rivian and Lucid Motors are also using cylindrical cells 21700 in their vehicle models (R1T, R1S and AIR Dream, Air GT respectively). BMW along with CATL and EVE energy have announced that its NEUE KLASSE type models will use the 46mm diameter geometry cylindrical cells too. The contract awarded are in the double digit billions euro range.

Thus, in this article we thought to compare the various cell sizes and see the different specification for 4680 vs 21700 vs 18650.

Whenever you look at a new design of pack it is important to some benchmarking of that design in the context of other packs. Any new pack will be measured against some key pack metrics and hopefully using a standard list of benchmarking data. Hence a key part of is to collect together some of the benchmarking material available for some of the important packs.
