Recently, Mercedes-Benz announced that the new all-solid-state battery technology developed in cooperation with the American company Factorial has achieved a significant breakthrough and is expected to increase the cruising range of electric vehicles by 80%.

It is reported that Factorial focuses on the research and development of all-solid-state battery technology and claims that its technology can significantly improve the endurance and safety of electric vehicles and reduce costs compared with existing technologies on the market.

In 2022, Factorial successfully raised US$200 million, with investors including Mercedes-Benz, Stellantis and Hyundai Motor. Factorial has been advancing its proprietary solid-state FEST (Factor Electrolyte System Technology) platform for several years. This summer, the company delivered all-solid-state batteries based on the FEST platform to Mercedes-Benz, and on Tuesday launched its latest breakthrough product, Solstice. The new all-solid-state battery was co-developed with Mercedes and is designed to power Mercedes' next-generation models. Factorial said its sulfide-based system effectively solves the design problems of flammable liquid electrolytes in traditional lithium-ion batteries and remains stable at temperatures exceeding 90 degrees Celsius. This safer design reduces the need for heavy-duty cooling systems, helping to reduce costs. Factorial's new all-solid-state battery has an energy density of 450 Wh/kg. It claims that the new technology can significantly improve the range of electric vehicles, reduce weight and improve overall efficiency. The company aims to provide future electric vehicles with a driving range of more than 600 miles (approximately 965.61 kilometers) while reducing weight by 40% and reducing battery size by 33% compared to traditional lithium-ion batteries. Factorial expects this new all-solid-state battery to be put into production by 2030, marking a major advancement in electric vehicle technology and heralding future electric vehicles with longer range and higher performance.
