Mercedes-Benz signs supply deal with Rock Tech Lithium for EV-ramp up.

Starting in 2026, including a qualification period, this allows the Stuttgart-based luxury carmaker to get its battery partners supplied with raw material to rapidly scale up its production of fully electric vehicles.

Mercedes-Benz plans to go all electric by the end of the decade, wherever market conditions allow, requiring the brand with the three-pointed star to open new sources of raw materials with new partners. As part of the agreement, Rock Tech Lithium plans to supply battery-grade lithium hydroxide to Mercedes-Benz battery partners from a converter based in Guben, Brandenburg, Germany. Lithium hydroxide is needed for the production of lithium-ion batteries which are used in Mercedes-Benz electric vehicles.

The strategic partnership between Rock Tech and Mercedes-Benz was announced during a German-Canadian summit in Toronto in August this year following the signing of a Memorandum of Understanding between Mercedes-Benz AG and Canada to explore deeper cooperation across all stages of the automotive value chain, focusing on natural resources development.

The supply agreement provides that both companies will cooperate in creating a roadmap to achieving CO₂ neutral production of lithium hydroxide by the end of 2030. Additionally, it requires that all lithium hydroxide supplied by Rock Tech shall be sourced from mining sites audited by the Initiative for Responsible Mining Assurances ("IRMA").

Responsibly mined and processed raw materials provide the foundation for a sustainable all-electric Mercedes-Benz vehicle fleet. Respect and protection of human rights as well as of the environment are decisive criteria for choosing sourcing partners. In close cooperation with its suppliers the Stuttgart-based luxury car maker with the three-pointed star is therefore working on finding levers for the consistent reduction of CO₂ as well as joining forces in order to reduce the amount of rare earth metals per electric drive significantly.

Rock Tech  is a cleantech company on a mission to produce lithium hydroxide for EV batteries. The company plans to build converters at the door-step of its customers, to provide supply-chain transparency and just-in-time delivery. Furthermore, Rock Tech has gathered one of the strongest teams in the industry. It holds itself accountable to strict ESG standards and plans to source raw material from its own mineral project in Canada as well as procuring it from responsibly producing mines. In the years to come, the company aims to extract its material from discarded batteries. Rock Tech’s goal: to create a closed-loop lithium company.
