Next-generation solid-state battery cells.

January 27, 2022 – Mercedes-Benz and ProLogium, a leader in solid-state batteries, 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 integration of the solid-state battery technology into a range of passenger vehicles in the second half of the decade.

Mercedes-Benz plans to go all electric by 2030 wherever market conditions allow. By partnering with leading companies in the fast evolving field of solid-state technology, Mercedes-Benz is pushing ahead its research and development activities, fostering further leaps in battery technology and continuously expanding its network of top-flight tech partners to ensure that it has access to the most up-to-date technologies.

We believe that range and efficiency are the new industry benchmarks for electric cars. Solid-state technology helps to cut down battery size and weight. This is why we are partnering with companies like ProLogium to ensure that Mercedes-Benz continues to break new ground in the automotive sector - for the benefit of our customers.

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.

Solid-state technology

Solid-state battery cells are one of the key levers for determining cost, scalability and energy density in the area of electric vehicle batteries. The solid-state electrolyte allows for the use of materials with high storage capacity, high-ionic conductivity, and higher chemical stability. The innovative materials and design of solid-state batteries can almost double the range of today’s conventional Li-ion battery cells.
