Do we know who makes the cells in the new J1.2 battery. We know they switched to a 8-1-1 chemistry, and I've seen mentioned that they dumped LG. Who makes the new modules?

I just queried ChatGPT…


As of February 2025, the Porsche Taycan’s new J1.2 battery is produced by LG Chem. The battery pack comprises 33 modules, each containing 12 LG Chem pouch cells, totaling 396 cells.

I asked “ Who makes the 2025 Porsche Taycan’s J1.2 battery?”

ChatGPT response:

Porsche has been actively investing in advanced battery technologies. In May 2022, Porsche announced plans to produce lithium-silicon EV battery cells in collaboration with Group14 Technologies, aiming for production in Germany by 2024. Additionally, in August 2024, Porsche agreed to provide capital in a restructuring deal with German battery maker Varta, securing access to high-performance batteries for its hybrid and electric sports cars.

However, as of now, the Taycan’s J1.2 battery continues to utilize cells from LG Chem.

So it appears we may begin to hear more about Porsche’s partnership with German battery maker “Varta” moving forward but apparently Porsche is still using LG Chem cells.
