Electrive reports that the new battery, called Solstice, has an energy density of up to 450 Wh/kg, which could increase the range by up to 80%, as well as make the vehicles lighter. Because of the collaboration between the two companies, Mercedes-Benz is seen by Factorial as a key customer in the future.

The solid-state cell developed by Factorial Energy uses a dry cathode design, making production more sustainable and efficient compared to other solid-state cells. Factorial Energy also wants to implement the new batteries in consumer electronics, such as phones and laptops.

Siyu Huang, CEO and co-founder of Factorial, said that "Solstice not only will enhance the range and performance of electric vehicles but also aligns with our vision for a more sustainable future."

Markus Schäfer, Chief Technology Officer and Member of the Board of Management of Mercedes-Benz Group AG, added that "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."

Back in 2022, Mercedes-Benz led a 200 million USD funding round for Factorial, which saw participation from other important carmakers, such as Stellantis. The battery developer also signed supplying agreements with Korean car group Hyundai-Kia.
