Porsche and Customcells to produce high-performance batteries

Luxury sports car manufacturer Porsche AG and battery manufacturer Customcells have announced a joint venture called Cellforce Group GmbH, which will produce high-performance batteries near the Weissach Development Centre in Germany.

The Federal Republic of Germany and the state of Baden-Württemberg are funding the project with around 60 million euros, while Porsche has invested a “high double-digit million” amount into the venture.

Porsche Executive Board Chairman Oliver Blume says the new Porsche subsidiary will be instrumental in driving forward research, development, production, and sales of high-performance battery cells.

“This joint venture allows us to position ourselves at the forefront of global competition in developing the most powerful battery cell and make it the link between the unmistakable Porsche driving experience and sustainability. This is how we shape the future of the sports car,” Blume said.

Porsche will hold an 83.75 per cent stake in the new venture, and the new battery tech will be tested in the motorsport arena while its electric Taycan sports car also receives leading technical features from the racetrack.

The new high-performance Cellforce battery cell reportedly uses silicon as the anode material, which the companies say are likely to provide a significant boost to the power density compared to current batteries. Thus, the battery can offer the same energy content, while being smaller in physical size.

The companies claim the new chemistry also reduces the internal resistance of the battery, allowing it to absorb more energy during its recuperation phase and offer improved performance for fast charging.

International chemical company BASF has been chosen as a cell development partner for the next generation of lithium-ion batteries. As part of the collaboration, BASF is providing high-energy HED NCM cathode materials for high-performance cells that enable fast-charging and high energy densities.

The goal for the planned production plant is to reach a minimum annual capacity of 100Mwh, the equivalent of high-performance batteries for 1,000 vehicles.

“With the founding of Cellforce today, Porsche and Customcells are sending an important signal: electrification is one of the central pillars of the energy and transport transition and modern storage technology is a key technology of the future,” said Baden-Württemberg Minister-President Winfried Kretschmann.

Porsche is aiming for 2030 to achieve overall carbon neutrality throughout the entire production process and life cycle of its new vehicles.
