BMW Gen6 Battery System

.....
46120
Nominal energy: 148 to 180Wh
Mass: ~0.53kg
Diameter: 46mm
Height: 120mm

The 120mm high cell is definitely for the larger SUV’s as this will result in a battery pack height of around 155 to 170mm (6.7") at best.

.....
Several OEMs such as BMW and GM as well as start-ups like Nio, Rivian and Lucid Motor have announced their intention to use large cylindrical cells for future vehicle generations. More precisely, BMW plans to use 4695 (420-450 g, ~140 ml, 32-36 Ah) and 46120 (530-560 g, ~180 ml, 40-46 Ah) cells in its upcoming next-generation "Neue Klasse" electric cars, expected by 2025.

Potentials of 46 mm cylindrical cells: On the way to the new standard format
by Dr. Christoph Neef / April 11, 2023
https://www.isi.fraunhofer.de/en/bl...potenziale-standardformat-batteriezellen.html

.....
Comparing the different cell versions from 4640 to 46120, it can be assumed that the overall manufacturing effort is quite similar. Even the production of the longer cells with a height of 120 mm likely does not lead to any significant reduction in assembly cycle times compared with the shorter formats. Only the electrolyte wetting process is likely to scale significantly with the cell length. The bottom line is that the higher energy per cell in the comparison between 4680 and 46120 could nevertheless result in cost savings of up to 20% in assembly. At the level of total cell costs, however, this saving is again put into perspective, since the share of assembly costs in total costs is likely to be only 5 to 7% due to the currently very high material prices.

Samsung SDI expands battery factory to manufacture 46120 batteries in Europe
18 August 2023
https://batteryindustry.tech/samsun...ory-to-manufacture-46120-batteries-in-europe/

.....
Samsung SDI, the South Korean battery maker, is planning to expand its battery factory in Goed, Hungary within the year. The expansion, called stage two, will allow the company to manufacture batteries with a diameter of 46mm. Customer BMW has specifically requested Samsung SDI to produce 46120 batteries, which are 46mm in diameter and 120mm in length.

.....
In addition to the 46120 batteries, Samsung SDI is also anticipated to manufacture 4680 and 4695 batteries. The 4680 batteries, popularized by Tesla, are gaining traction among electric vehicle manufacturers. Samsung SDI will start by developing the 4680 batteries before moving on to produce 4695 and 46120 batteries.

To support this expansion, Samsung SDI already operates a pilot line for the batteries in Cheonan, South Korea, and it is expected to commence production in Malaysia as well.
