German sports car manufacturer Porsche announced Monday it will build a battery plant through a joint venture with compatriot Customcells, Kallanish reports.

The so-called Cellforce Group is 83.75% owned by Porsche and headquartered in Tübingen, Germany, which the JV partners consider to be a location candidate for the battery factory. The plant will have a minimum capacity of 100 megawatt-hours, which would supply batteries to around 1,000 vehicles, Porsche says in a statement.

The carmaker claims its “double digit million” investment in high-performance battery cells reflects its “electric offensive.” The project has received €60 million ($71.4m) in grants from the German government and the Baden-Württemberg state.

“The battery cell is the combustion chamber of the future. As a new Porsche subsidiary, the Cellforce Group will be instrumental in driving forward the research, development, production and sales of high-performance battery cells,” comments Oliver Blume, chairman of Porsche. “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.”

The companies are betting on silicon anodes to deliver the high-energy density to power sport motors.

“With this material, it now seems possible to significantly boost the power density compared to current good series batteries,” the carmaker says. It notes the chemistry gives the same power with smaller size batteries, has reduced battery internal resistance and withstands high temperatures.

Basf has been picked as the exclusive provider of the so-called HEDTM NCM cathode materials for the high-performance cells. The German chemical manufacturer is the cell development partner for the next generation of lithium-ion batteries for Porsche, through its upcoming production in 2022 at both facilities in Finland and Germany.

Porsche plans to be a carbon neutral carmaker by 2030, with the target covering the entire production process and lifecycle of its new vehicles.
