According to Electrive, Mahle officials said that the goal of the collaboration is the development of highly efficient, dense and fast-charge-capable batteries that have a long operational lifetime. Engineers at the two companies will also look into how batteries age and what causes early failures in EV-grade cells.

Vincent Yang, CEO and founder of ProLogium Technology, said that "I believe ProLogium’s joint forces with Mahle propel the commercialization of reliable and efficient solid-state battery solutions that advance electric vehicles to the next level. With the collaboration, we are on track to achieve a net-zero future."

In June, ProLogium showcased a new type of solid-state battery for EVs, which has double the energy density, meaning that it can store twice as much power in a cell of a certain size and at the same time, it was able to reduce the weight and the number of individual cells that make up a battery pack for EVs.

ProLogium also plans to build a battery plant in France and this could be the company's first outside Taiwan. Mercedes-Benz and Vinfast are some of the companies that invested in ProLogium, who currently has a production capacity of 3 GW in its home country.
