Mercedes-Benz, ProLogium Boost Solid-State Battery Development
Taiwan's ProLogium Technology grants Mercedes-Benz priority access to Gen4 solid-state cells, deepening their partnership for electric vehicle power units.

Partnership Deepens on Battery Tech
ProLogium Technology, a Taiwanese battery producer, has signed a joint testing agreement with Mercedes-Benz. This accord gives the German vehicle manufacturer preferential entry to ProLogium's newest Gen4 solid-state battery cells. The objective focuses on advancing power unit technology for future electric vehicles.
This development builds on a nearly decade-long working relationship between the two companies in advanced battery solutions.
Priority Access to Gen4 Cells
Under the agreement, Mercedes-Benz will gain early evaluation access to ProLogium's Gen4 solid-state cells. This arrangement ensures the automaker remains at the forefront of battery innovation. ProLogium has developed these advanced cells to offer improved energy density and safety characteristics compared to conventional lithium-ion batteries. The testing phase is expected to provide critical data for integrating this technology into production models.
Long-Term Focus on EV Innovation
The extended collaboration between Mercedes-Benz and ProLogium Technology demonstrates both companies' sustained investment in electric vehicle battery innovation. Their nearly ten-year partnership shows a long-term focus on developing next-generation power units.
This continued effort aims to bring solid-state battery technology closer to mass production, a key step for the wider adoption of electric vehicles.
This partnership reveals how Taiwanese battery technology continues to attract significant global automotive investment. The agreement could prompt further European automakers to seek similar development partnerships with Asian battery manufacturers, particularly those in Taiwan and South Korea, to secure access to advanced solid-state cell capacity.
Companies in these Asian economies should prepare for increased demand for specialised engineering talent and manufacturing infrastructure to support such high-tech collaborations over the next five years.
