FEV and ProLogium will market solid ceramic electrolyte batteries in 2023

German engineering services provider FEV has teamed up with Taiwanese solid electrolyte battery specialist ProLogium to develop dedicated ceramic electrolyte-based battery systems for its customers. Their automated plantin which the prototypes of these solid cells are already being manufactured, will start operating in 2023. The agreement also includes the creation of the sales network and a cell and module verification system based on SSB technology.

ProLogium has a story behind seven years in the manufacture of solid batteries. Those presented at CES 2020 used the “Multi Axis BiPolar +” MAB technology that improved the energy density of its previous developments. The company claimed to have eliminated the NMC 811 cathodes, unstable in terms of supply and performance, for a new design that maximized the advantages of solid-state batteries, improving “assembly efficiency”.

At the same event, the Taiwanese supplier announced its strategic cooperation agreement with several automobile manufacturers to mount the new solid-state battery packs with ceramic electrolyte in their electric cars. Since January, Mercedes has become one of its biggest investors, along with VinFast and Nio who also have ties to the company.

ProLogium “ideally complements our 360-degree battery development,” says Professor Stefan Pischinger, President and CEO of the FEV Group. “Thanks to our unique development and testing capabilities, we are able to design state-of-the-art technology that meets all regulatory requirements and customer demands around the world,” he added, explaining FEV’s participation in this agreement. Engineering manages a large test and development center independent battery manufacturer near Leipzig, Germany, dedicated specifically to high-voltage batteries.

Pischinger lists the common advantages that solid electrolyte based batteries have over liquid solution lithium ion batteries and specifically over their SSB technology: “they offer an advantage in additional autonomy, due to their lower weight and volume for the same energy capacity. “. In this sense, FEV adds to the chemical innovation of these batteries, the package-level integration and the algorithms to control and manage its operation.

ProLogium claims that on its automated pilot production line it has manufactured nearly 8,000 sample cells of solid state batteries. These have been sent to car manufacturers around the world for testing and module development. Its ceramic electrolyte lithium battery plant will reach “a level of production that will be measured in GWh” and will be the first in the world to be operational, since it is expected to start operations in early 2023. Its goal is to start scaling production from the third quarter of that year with the intention of expanding its market throughout the world.

Until now, ProLogium’s ceramic solid electrolyte batteries in real life mainly power small devices like watches. The first advance in electric mobility can be seen in the scooter developed with Gogoro. The project is in the prototype stage with a current capacity of 2.5 kWh, an increase of 47% over the liquid electrolyte lithium-ion battery.
