Mercedes partners Factorial to develop solid-state batteries

The new Solstice solid-state battery offers up to 450 Wh/kg energy density, boosting EV range by up to 80% and reducing environmental impact with its eco-friendly design.

USA-Factorial Inc., solid-state battery technology collaboration with Mercedes-Benz has developed the Solstice-solid-state battery that can revolutionize the safety, performance, and sustainability of the next generation of electric vehicles (EVs).  Solstice is set to achieve a breakthrough energy density of up to 450Wh/kg and incorporates a novel dry cathode design for more efficient and sustainable production.

Solstice high energy density can extend EV range up to 80% while significantly reducing vehicle weight and increasing vehicle efficiency.

Mr. Siyu Huang, CEO and Co-Founder of Factorial, said, “Solstice embodies our team’s technology leadership and highlights the potential of solid-state batteries to overcome the most significant hurdles to electric vehicle adoption. Solstice not only will enhance the range and performance of electric vehicles but also aligns with our vision for a more sustainable future. We’re grateful to have Mercedes-Benz’s continued support, which underscores our ability to meet the needs of global automakers now and in the future."

Solstice is revolutionizing battery manufacturing with its eco-friendly dry coating technology, which eliminates hazardous solvents and the energy-intensive formation process. This technology cuts costs, reduces energy use, and lessens environmental impact, paving the way for a more sustainable future in battery production.

Mr. Markus Schafer, Chief Technology Officer and Member of the Board of Management at Mercedes-Benz Group AG, said, "The Solstice solid-state battery technology represents another landmark milestone in our partnership with Factorial, which is a cornerstone of Mercedes-Benz's strategy and commitment to leading the charge in battery development. 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.”
