Daimler’s Mercedes-Benz unit is taking an equity stake in European battery cell manufacturer Automotive Cells Company (ACC) – a joint venture set up by Stellantis and TotalEnergies.

Mercedes-Benz is planning to go fully electric by the end of the decade – wherever market conditions allow – and to reach its target, the company needs a total battery production capacity of more than 200 Gigawatt hours by the end of the decade. It plans to build eight cell factories worldwide together with partners, four of them in Europe.

Joining ACC is the next step on Mercedes’ strategic course, it said.

“Mercedes-Benz pursues a very ambitious transformation plan and this investment marks a strategic milestone on our path to CO2 neutrality. Together with ACC, we will develop and efficiently produce battery cells and modules in Europe – tailor-made to the specific Mercedes-Benz requirements,” said Ola Källenius, CEO of Daimler AG and Mercedes-Benz AG. “This new partnership allows us to secure supply, to take advantage of economies of scale, and to provide our customers with superior battery technology. On top of that we can help to ensure that Europe remains at the heart of the auto industry – even in an electric era: With Mercedes-Benz as a new partner, ACC aims to more than double capacity at its European sites to support Europe’s industrial competitiveness in the design and manufacturing of battery cells.”

The entire ACC project will require an investment volume of more than seven billion euros – in a combination of equity, debt and subsidies – to reach a capacity of at least 120 Gigawatt hours in Europe by the end of the decade.

Mercedes-Benz will invest a mid-three-digit-million euros amount next year. In total, the investments are expected to remain below one billion Euros. The transaction is subject to customary closing conditions, including agreement on definitive documentation and regulatory approvals.

Yann Vincent, CEO of ACC says: “To have Mercedes-Benz join us as a new shareholder is a major milestone for ACC. Mercedes-Benz will bring a vote of confidence in our technology roadmap and product competitiveness that significantly strengthens ACC’s business potential and underpins our ambitious growth plans. This is our contribution to an electric and sustainable future.”

“Mercedes-Benz will take a strategic 33 percent equity stake in ACC. Following the investment, we will hold two out of six seats on ACC’s Supervisory Board alongside TotalEnergies and Stellantis as equal shareholders,”said Markus Schäfer, Member of the Board of Management of Daimler AG and Mercedes-Benz AG; responsible for Daimler Group Research and Mercedes-Benz Cars COO. “Our goal is to continue to integrate the most advanced and sustainable battery cells in our EQ models. Therefore, we will provide our technological and production know-how to ACC. Mercedes-Benz will further complement high end cell development with its newly planned pilot plant ‘Drive Systems Campus’ in Stuttgart from 2023 onwards.”

ACC will supply Mercedes-Benz with high-performance battery technologies from its production locations from the middle of the decade. The battery cell manufacturer is examining the expansion of its production network to include further locations in Europe.

Mercedes-Benz is pursuing widespread research and development activities in the field of battery technology. The company will contribute this expertise and support the expansion of ACC’s production network based on the brand’s benchmark quality standards. With Saft, an affiliate of TotalEnergies, Mercedes-Benz has a partner with over 100 years of experience in the field of long-life batteries and battery systems for applications critical to safety, back-up power and electric and hybrid drives. Stellantis brings industrialisation expertise to the joint venture through its brand diversity, size and global footprint. Together with its partners, Mercedes-Benz customers can benefit from the joint venture’s unique combination of technological know-how, production experience and scale.

Modular and standardised battery kit

Mercedes-Benz relies on a modular, highly standardised battery kit that allows the integration of battery cells and modules from different development partners through uniformly designed components and interfaces. The aim of the partnership is the joint development of cells and battery modules that meet the high energy density, charging power and performance requirements of Mercedes-Benz. The joint expertise of the partners in cell technology and cell production means that distinctive variations in the modular system can be optimally realised with respect to cell chemistry and cell height. The partners are also exploring further leaps in battery technology, for example with regard to high silicon anode and solid-state batteries.

With Ambition 2039, Mercedes-Benz is pursuing the goal of CO2 neutrality along the entire value chain. The CO2 neutral production of battery cells is an important component, and a specific requirement for all partners. ACC will therefore primarily use electricity from renewable energies for the production of high-performance battery technologies. Other important sustainability aspects are the responsible sourcing of raw materials and the intelligent use of resources. For the battery cells, only battery raw materials which were extracted from certified mines will be used. In addition, the partners are reducing critical materials with the use of new technologies. For a closed raw material cycle, ACC battery cells will be over 95% recyclable. The battery cell manufacturer is an important partner for the European Union to implement the sustainability requirements for a green battery in Europe as part of the Green Deal.

About ACC

ACC was founded in 2020 and to date combines the expertise of Stellantis, TotalEnergies and Mercedes-Benz with complementary skills and experience. ACC’s goal is to become the European market leader for car battery cells and modules that allow clean and efficient mobility for all. The R&D center in Bordeaux (France) is operational and the pilot site in Nersac (France) will start production at the end of this year.
