Under the strategic cooperation arrangements,ProLogium plans to provide solid-state battery cells to VinFast starting from 2024 to support its next generation line-up. ProLogium's first major solid state battery plant,which is slated to launch in early 2023,will devote a significant portionof the facility's production capacity to supply VinFast. In the future,ProLogium and Vinfast may also establish a joint-venture solid-state battery factory in Vietnam.

Solid-state batteries are among the most promising technologies to offer advantages in terms of safety,energy density,hyper fast-charging capability,recyclability,weight optimization,costs,and lifetime.

The partnership with ProLogium is an integral part of VinFast's battery strategy. Through this strategic arrangement,VinFast aims to secure the battery supply with world's leading technology,enhance control over the quantity and type of its battery supply to meet the needs of each VinFast EV line and the market's demands for high-tech,high-performance,safe,and environmentally friendly batteries.

"VinFast has focused on investing and building strategic partnerships with leading companies in the industry and breakthrough technology companies to quickly grasp and apply technologies for smart and sustainable mobility solutions," said Ms. Le Thi Thu Thuy,Vingroup Vice Chairwoman,and VinFast Global CEO. "ProLogium is one of our key partners,helping VinFast quickly master the supply of solid-state batteries while continuing to deliver EV products with advanced battery technology for a more enjoyable and safer driving experience."
