At the end of last month Factorial Energy issued a press release which announced that:

Factorial Energy, Hyundai Motor Company and Kia Corporation are partnering to test Factorial’s novel solid-state battery technology and its integration in Hyundai electric vehicles. Under the Joint Development Agreement, which includes a strategic investment, the companies will integrate Factorial technology at the cell, module, and system levels, perform vehicle-level integration, and co-develop specifications for manufacturing Factorial’s batteries. The announcement is Factorial’s first major strategic investment from a major automotive Original Equipment Manufacturer (OEM) group and deepens its existing research relationship with Hyundai.

Factorial has developed breakthrough solid-state technology that addresses key issues holding back widescale consumer adoption of electric vehicles: driving range, and safety.

Factorial’s advances are based on FEST™ (Factorial Electrolyte System Technology), which leverages a proprietary solid electrolyte material that enables safe and reliable cell performance with high-voltage and high-capacity electrodes and has been scaled in 40Ah cells that perform at room temperature. FEST™ is safer than conventional lithium-ion technology, extends driving range by 20 to 50 percent, and is drop-in compatible for easy integration into existing lithium-ion battery manufacturing infrastructure.

Earlier today Stellantis issued a press release which also announced an investment in Factorial Energy:

Stellantis N.V. and Factorial Energy announced today the signing of a joint development agreement to advance Factorial’s high-voltage traction solid-state battery technology. The agreement also includes a strategic investment from Stellantis.

“Our investment in Factorial and other highly recognised battery partners boosts the speed and agility needed to provide cutting-edge technology for our electric vehicle portfolio,” said Stellantis CEO Carlos Tavares. “Initiatives like these will yield a faster time to market and more cost-effective transition to solid-state technology.”

Factorial has developed breakthrough solid-state technology that addresses key issues holding back wide-scale consumer adoption of electric vehicles: driving range and safety.

“It is a great honor to partner with Stellantis, a leading global mobility player, which has some of the most iconic auto brands in the world,” said Siyu Huang, Co-founder and CEO of Factorial Energy. “It is an incredible opportunity for us to advance the adoption of our clean, efficient and safe solid-state battery technology to the mass market.”

Stellantis announced during its EV Day program in July 2021 its target of having the first competitive solid state battery technology introduced by 2026.

One cannot help but wonder how well this exciting new battery technology will handle the modest cycling requirements of V2G technology!
