Building on its nearly 10-year history, Mercedes-Benz secured first rights to ProLogium’s latest Gen4 solid-state EV battery cells.
Battery tech is already light-years ahead of where it was just a few years ago. The next generation of batteries will be even safer and more efficient.
Solid-state batteries are widely considered the gold standard for next-gen EV batteries, promising drastically higher energy density, enabling faster charging times, longer driving ranges, and superior safety.
Mercedes-Benz continues advancing the new battery after announcing a joint test agreement with ProLogium on Thursday.
The agreement gives Mercedes priority access to ProLogium’s latest Gen4 Superfluidized Inorganic Lithium Ceramic Battery cells.
Mercedes will test the solid-state battery cells’ electric, thermal, and safety performance at “specialized external testing institutes” and facilities.
ProLogium’s Gen4 battery platform is designed to overcome some of the biggest hurdles in bringing solid-state batteries to market, including scalable manufacturing and a competitive cost structure.
Using a non-flammable inorganic electrolyte, ceramic separator, and ProLogium’s proprietary safety mechanism, the architecture supports fast charging, high power output, and superior performance in cold temperatures.
Mercedes and ProLogium have been working together since 2016, moving from early hybrid-solid-state batteries to its latest Gen4 cells.
The two companies have validated multiple lithium ceramic battery formats, including pouch cells, the first next-generation prismatic cells, and ProLogium’s Bi-Polar technology.
ProLogium opened its first GWh-class gigafactory in Taiwan in May 2024. In February, it held a groundbreaking ceremony for its second battery gigafactory in Dunkirk, France.
0 GWh of annual production capacity, which is expected to be “progressively achieved” by 2030.
