Trumpf & Cellforce announce strategic partnership
The battery cell joint venture between Porsche and Customcells, Cellforce, has entered into a strategic partnership with the machine manufacturer Trumpf from Baden-Württemberg. As part of the cooperation, high-precision laser technology from Trumpf will be used in battery cell production.
As reported in December 2021, Cellforce is building its factory in the inter-municipal economic area of Reutlingen-Nord/Kirchentellinsfurt. High-performance pouch cells for “special automotive applications” are to be produced there starting from 2024, primarily focusing on electric racing cars and particularly high-performance road vehicles from Porsche.
The joint venture between Porsche and Customcells says it is already using Trumpf lasers in a pilot plant. According to the statement, the laser technology has proven itself on the pilot plant and is also to be used in series production in Reutlingen-Nord/Kirchentellinsfurt in the future.
“Our goal is to produce one of the most powerful battery cells in the world,” says Markus Gräf, Chief Operating Officer of the Cellforce Group. “We want to raise the energy density, performance and fast-charging capability of the battery cell to a new level.”
The factory is known to initially produce cells with a production capacity of 100 MWh per year. According to Cellforce, this is equivalent to high-performance battery cells for around 1,000 vehicles. “The laser is the decisive tool for efficient production of battery cells, without which e-mobility would really not be possible” says Christian Schmitz, CEO of Trumpf Lasertechnik.
How exactly the lasers are used in cell production is not clear from the Cellforce announcement. There are currently more than 30 different laser applications in the production of cells, it says in general terms.
