American solid-state battery developer Factorial Energy has announced that it has received investment from Mercedes-Benz and Stellantis. Each of the automakers intends to work with Factorial Energy to develop solid-state batteries for electric vehicles, following the lead of Hyundai and Kia, which invested in Factorial Energy in early November.

According to Factorial Energy, its specialists have succeeded in making a breakthrough in solid-state batteries for electric vehicles, capable of increasing mileage on a single charge by 20-50%.
The proprietary FEST (Factorial Electrolyte System Technology) technology, which features a solid electrolyte, provides a safer and more reliable operation of a large-capacity cell at the same price as traditional lithium-ion batteries. The development has already been implemented in cells with a capacity of 40 Ah, operating at room temperature. The production of such batteries can be mastered at most of the existing industries engaged in the production of lithium-ion batteries.
