ProLogium; First Gigafactory for 75 kWh solid-state ceramic EV batteries is opened by solid-state battery manufacturer.

ProLogium, a partner of Mercedes-Benz, is building the first solid-state battery Gigafactory and another $6 billion plant in France. In the first stage, Gigafactory, ProLogium’s solid-state battery plant, will supply enough lithium ceramic cells for 26,000 electric vehicles.

ProLogium, a partner of Mercedes-Benz, has launched the first Gigafactory for electric vehicle batteries in Taiwan, with the aim of producing solid-state batteries in large quantities. The corporation also decided to build a larger, $6 billion solid-state battery factory in Europe rather than the US; it will open in 2027 and use the Taoke Gigafactory as a model for its development.

When ProLogium’s Taiwan operation reaches its anticipated 2GWh yearly output, it will begin selling solid-state batteries with an average capacity of 75kWh, which will be sufficient for 26,000 electric cars to customers. Hence, the Gigafactory moniker.

ProLogium showcased its exclusive 106Ah solid-state lithium ceramic cells during the inauguration ceremony, which was also attended by Mercedes-Benz and French officials in charge of the $6 billion Dunkirk factory. Presenting ProLogium’s patented process for manufacturing solid-state batteries, the CEO said, “We have overcome the bottlenecks in traditional batteries and this breakthrough combines performance, cost efficiency, and resource circulation, manifesting a new universe for the battery industry.”

While ProLogium appears prepared to begin supplying solid ceramic electrolyte packs to customers immediately, Samsung recently made significant progress in the mass manufacture of solid-state batteries. Toyota is anticipated to introduce its first electric vehicles (EVs) with solid-state batteries in 2027.

If it seems like a low amount, keep in mind that Toyota also anticipates producing only a few thousand EVs using its solid-state battery at launch, most likely under the Lexus brand. “The 26,000 electric vehicle capacity estimate is based on 2 GWh divided by 75 kWh per vehicle,” advises ProLogium.

Although the carmaker that will receive the first solid-state battery packs from ProLogium is yet unknown, Mercedes, a frequent investor, is undoubtedly a top contender.


Founded in 2006, ProLogium is a global leader in innovative next-generation battery technologies for vehicle, consumer, and industrial applications.

ProLogium is the first battery company in the world to mass-produce solid-state lithium ceramic batteries. Its proprietary technologies cover over 500 (applied or awarded) patents worldwide.

ProLogium’s automated pilot production line has provided nearly 8,000 solid-state battery sample cells to global car manufacturers for testing and module development.

ProLogium Technology’s GWh level solid-state lithium ceramic battery plant will be the first in the world to go online in early 2023, and it aims to begin scaling up by the second half of the year, followed by capacity expansion plans in major markets worldwide.
