"VinFast and ProLogium will become long-term strategic partners in the future and will enter into commercial agreements to develop battery pack designs using ProLogium's proprietary solid-state battery technology, "adhering to strict specifications on the parameters, quality, and safety for VinFast."
As part of the agreement, ProLogium plans to provide solid-state battery cells to VinFast starting from 2024 for the automaker's next-generation lineup.
A significant capacity of ProLogium's first major solid state battery plant, which is scheduled to launch in early 2023, will be devoted to supply VinFast. That facility will have a total annual output of 3 GWh of power at full capacity, enough to power 30,000 EVs with 100-kWh batteries. The two parties said they may also establish a joint-venture for a solid-state battery factory in Vietnam in the future.
