Mercedes-Benz develops solid-state batteries with ProLogium

Daimler's subsidiary Mercedes-Benz is also focusing on the development of solid-state batteries and is deepening its collaboration with specialist ProLogium for faster development of next-generation battery cells. The first jointly developed solid-state batteries are set to be used in test vehicles in the coming years. As part of the partnership, technological milestones have been agreed upon that aim to integrate solid-state technology into selected models within the second half of the decade, according to the manufacturer. The Stuttgart-based company states it will be "ready to go fully electric by the end of the decade, where market conditions allow."

The company is actively advancing its research and development activities in the rapidly evolving field of solid-state technology to secure access to the latest technologies. With the expertise of the new partner, the company even sees its leadership claim in battery technology strengthened.

"Efficiency and range are the new industry benchmarks for electric cars. Solid-state technology has the potential to significantly reduce the size and weight of the battery," says Markus Schäfer, Member of the Board of Management of Daimler AG and Mercedes-Benz AG, Chief Technology Officer responsible for Development and Procurement.

He points out that they have been testing battery cells for electric vehicles since 2016, as outlined by Vincent Yang, CEO and founder of ProLogium Technology. They are convinced that innovative technology must be supported by scalable production and aim to ramp up a new plant by the end of 2022 to initiate mass production. As part of the development partnership, the Swabians will take a seat on ProLogium's Board of Directors and deepen the collaboration through equity participation.

Solid-State Battery as Beacon of Hope

With solid-state technology, there is hope for a reduction in costs, scalability, and energy density. The solid electrolyte allows the use of materials with high storage capacity, high ionic conductivity, and higher chemical stability, according to outlines. The innovative materials and design of solid-state batteries have the potential to nearly double the range of today's conventional lithium-ion battery cells, believe Daimler engineers. The Swabians recently initiated a strategic shift and aim to accelerate the transition from "Electric first" to "Electric only" under this claim.
