Factorial Energy, a developer of solid-state battery technology, has announced the introduction of Solstice™, a new all-solid-state battery designed to improve the performance of electric vehicles (EVs). Developed in partnership with Mercedes-Benz, Solstice has a high-energy density that could potentially increase EV range by up to 80%.
The battery incorporates an innovative dry cathode design that is expected to improve manufacturing efficiency and sustainability. Solstice further complements Factorial’s existing FEST (Factorial Electrolyte System Technology) for automotive and electric mobility applications, while also expanding the company’s market reach into consumer electronics.
Key features of Solstice include:
- Energy density up to 450Wh/kg
- Targeted EUCAR safety rating of 2
- Stability at operating temperatures above 90 °C
- Potential reduction in cooling system requirements
Factorial Energy expects Solstice technology to be implemented by OEMs before the end of the decade. The battery manufacturing process eliminates hazardous solvents and energy-intensive steps common in traditional cathode manufacturing, potentially reducing operating costs and environmental impact.
Mercedes-Benz, a key development partner and customer, has expressed its support for the technology. Markus Schäfer, Chief Technology Officer of Mercedes-Benz Group AG, said that Solstice represents a significant advancement in the partnership with Factorial.
This announcement follows Factorial’s recent delivery to Mercedes-Benz of B samples of its solid-state battery cells using the FEST platform. Mercedes-Benz initiated a joint development agreement with Factorial in 2021, and led a $200 million investment round in the company in 2022.
Factorial expects Solstice to be available to customers in the electric mobility and consumer electronics industries by the end of the decade.
