Revolutionizing EVs: Mercedes-Benz and Factorial's Innovative Solid-State Battery

Mercedes-Benz and Factorial are partnering to develop Solstice, a solid-state battery projected to significantly enhance electric vehicle (EV) range by 80% and be ready for production by the end of the decade. The technology aims to reduce fire risks, production costs, and improve overall EV performance.

In a groundbreaking initiative, Mercedes-Benz and U.S. battery startup Factorial are collaborating to produce a revolutionary solid-state battery named Solstice, expected to dramatically enhance electric vehicle (EV) range by 80% and be ready for production by the decade's end.

Solstice boasts an energy density of 450 Watt-hours per kilogram, a game-changing feature that promises to reduce fire risk and enable lighter, more cost-effective cars. This innovation addresses the urgent need for increased EV range and cost reduction as sales stagnate in critical markets like Europe.

Factorial has already developed quasi-solid-state batteries, undergoing testing by automakers including Mercedes, with potential road deployment in 2026. CEO Siyu Huang highlighted the benefits of using existing lithium-ion battery production lines for quicker scaling. Overcoming challenges like poor cold-weather performance and battery expansion, the collaboration holds promise for a future where EVs are more efficient and sustainable.
