Porsche establishes a new joint venture subsidiary for high-performance battery cellsInnovative use of silicon instead of graphite anodes to significantly boost the battery power density
In the initial phase, the new
The goal for the planned production plant is to reach a minimum annual capacity of 100 MWh, equivalent to high-performance battery cells for around 1,000 vehicles.
The new high-performance battery cells, which rely on silicon as the anode material, offer the same energy content in a smaller size, with improved fast charging performance and high temperature resistance.

Parliamentary State Secretary at the Federal Ministry for Economic Affairs and Energy Thomas Bareiß: “I am delighted that the founding of the Cellforce Group joint venture has taken the decisive step towards this ambitious battery project. The project is a prime example of what we wanted to achieve with the IPCEI battery cell production initiative. We are pleased that we, as the Federal Ministry for Economic Affairs and Energy, can provide the necessary boost with this contribution to get another battery cell production started in Germany. Baden-Württemberg is increasingly becoming a battery hotspot and thus securing qualified workers at a highly innovative location. I wish all employees of the company all the best."
Mayor Boris Palmer: “In Tübingen, excellent research has always been ideally complemented by economic implementation and market readiness. We are pleased that another building block for more environmentally friendly mobility is to be built in our city in the future. The high-performance battery cells also fit perfectly with our ambitious climate protection programme to become CO2-neutral by 2030. This is the only way it can work: economic growth combined with ecological progress.”
The chemistry of the new high-performance cells relies on silicon as the anode material. With this material, it now seems possible to significantly boost the power density compared to current good series batteries. The battery can offer the same energy content in a smaller size. The new chemistry reduces the battery’s internal resistance. This allows it to absorb more energy during energy recuperation and at the same time it offers improved performance for fast charging. Another special feature of the Cellforce battery cell is the fact that it is better able to withstand high temperatures. These are all qualities which are highly valued in motorsport. In addition, use on the race track does not necessarily require the battery to function in sub-zero temperatures nor remain stable for years over many charging cycles – goals which have yet to be achieved with this new cell technology.
The world-leading chemical company BASF has been chosen as a cell development partner for the next generation of lithium-ion batteries. As a part of the collaboration, BASF is exclusively providing high-energy HEDTM NCM cathode materials for high-performance cells that enable fast charging and high energy densities. At BASF’s manufacturing facilities for primary products of cathode materials in Harjavalta, Finland, and for cathode materials in Schwarzheide, Brandenburg, Germany, BASF will be able to produce battery materials with an industry-leading low carbon footprint from 2022.
