ProLogium and Mercedes-Benz agree on developing solid-state battery cells for EVs
27 January 2022, 02:29:46
ProLogium, a leader in solid-state batteries, and Mercedes-Benz have signed a technology cooperation agreement to develop next-generation battery cells. The first Mercedes-Benz test vehicles equipped with solid-state batteries co-developed with ProLogium are expected to be introduced in the coming years. The companies also agreed on milestones that would enable the integration of the solid-state battery technology into a range of passenger vehicles in the second half of the decade.
ProLogium focuses on the development of next-generation batteries, including solid-state batteries with silicon anode, lithium metal anode, and bipolar technology. Since its origins, ProLogium has engaged on a technology path with safety, performance, and scalability in mind, and has planned a technology development roadmap that spans across the next generations of battery technology. Armed with 15 solid years of R&D and manufacturing experience, ProLogium's technology will be a strong force to contribute to the acceleration of the global energy transition.
Mercedes-Benz plans to go all-electric by 2030 wherever market conditions allow. With its solid-state battery R&D and manufacturing know-how, ProLogium is a strong partner for Mercedes-Benz to maintain its role as a leader in battery technology. Under the agreement, Mercedes-Benz will take a seat on the ProLogium board of directors. The investment by Mercedes-Benz will be used to support the development of the technology and ProLogium's plan of establishing production capacity in Europe.
