Mercedes will receive 46100 cells from LGES in 2028. Production is set to begin in Wrocław.
LG Energy Solution is set to supply Mercedes with new cylindrical 46100 cells starting in 2028, intended for the next generation of electric vehicles. The first production line of this type is expected to be established at LGES’s factory in Wrocław, Poland, but neither company has officially confirmed these plans yet.
The 46100 cells have a diameter of 46 mm and a height of 100 mm. They represent a new variant in the family of large cylindrical cells that LG Energy Solution has not previously introduced.
The Polish line is scheduled to begin deliveries in 2028
According to the South Korean website The Elec, construction of the production lines is set to start in 2027, with mass deliveries planned for 2028. Mercedes-Benz is expected to be the main buyer of cells produced at the Polish facility.
LGES is also considering an investment in module assembly. At this stage, it is unclear whether only individual cells will be produced in Wrocław or whether ready-made modules prepared for installation in Mercedes powertrains will also be manufactured there. The information comes from industry sources at The Elec and has not yet received official confirmation.
Before launching production in Poland, LG Energy Solution plans to set up a pilot plant at its Ochang facility in South Korea. Its purpose will be to adapt the process to meet the requirements of the future mass production line in Wrocław.
The 46100 format will add to the growing family of cells with a diameter of 46 mm. The best-known are the 4680 cells, which are 80 mm high and primarily used by Tesla. Variants such as 4695 and 46120 have also appeared on the market, with heights of 95 mm and 120 mm respectively. A cell exactly 100 mm high was not previously mentioned in LGES’s plans.
Mercedes Sources Cells from Multiple Manufacturers
The Korean conglomerate began producing 4695 cells in Ochang at the end of 2025. Earlier reports from April 2026 indicated that LGES’ factory in Arizona would start manufacturing various 46 series cells, from 4680 to 46120, by the end of 2026.
However, Mercedes does not rely solely on one supplier for its future electric vehicles. Since October 2024, the manufacturer has signed four long-term contracts with LG Energy Solution, but in April 2026 it also entered its first such agreement with Samsung SDI. CATL is also part of its supplier network, and previously Mercedes used cells from SK On and Farasis.
The biggest unknown remains the vehicle that will receive the 46100 format. The available information does not specify which platform, package capacity, or Mercedes model is involved. For now, we have the specific cell size, estimate, and delivery date, but without an official statement from both companies.
