Factorial announced the introduction of Solstice, an all-solid-state battery that can revolutionize the safety, performance and sustainability of the next generation of electric vehicles. The battery was developed in partnership with Mercedes-Benz.
An all-solid-state Solstice battery is designed to achieve energy densities of up to 450Wh/kg and features a novel dry cathode design for more efficient and sustainable manufacturing.
Solstice's high energy density can extend EV range by up to 80% while significantly reducing vehicle weight and increasing vehicle efficiency. Its sulfide-based all-solid-state electrolyte system addresses safety concerns associated with more flammable and volatile liquid electrolyte designs, targeting an EUCAR safety rating of 2 and maintaining stability at operating temperatures above 90°C. This also has the potential to reduce cooling system requirements within the battery pack to lower overall vehicle costs.
Solstice is poised to improve battery manufacturing. Through a novel dry coating process, Solstice eliminates the need for hazardous solvents and energy-intensive steps commonly used in traditional cathode manufacturing. The technology also bypasses the formation process, the most energy-intensive step in lithium-ion battery manufacturing.
The announcement follows the delivery of B-samples of the solid-state battery cells to Mercedes-Benz. The automotive group entered into a joint development agreement with Factorial in 2021 and led a $200 million investment round for Factorial in 2022. Stellantis also participated in this round. There is also a development agreement with Hyundai-Kia.
