Factorial has launched an all-solid-state battery developed with customer Mercedes-Benz to extend EV driving range.

Solstice incorporates a dry cathode design for more efficient production. It delivers specific energy of up to 450 Wh/kg while reducing vehicle weight and increasing efficiency, which can extend EV range by up to 80%, according to the company.

The battery’s sulfide-based all-solid-state electrolyte system is designed to address safety concerns associated with more flammable and volatile liquid electrolyte designs, maintaining stability at operating temperatures over 90° C. This also has the potential to reduce the cooling system requirements within the battery pack, in turn reducing costs.

Factorial expects OEMs in the EV and consumer electronics industries to introduce the technology before the end of the decade.

The launch follows Factorial’s delivery of B-samples of its solid-state battery cells to Mercedes-Benz.

“Solstice offers further improvements in energy density and safety features that will help us develop electric vehicles that set new standards in range, cost, and performance,” said Markus Schäfer, Chief Technology Officer and Member of the Board of Management at Mercedes-Benz.
