Highlights
- Mercedes-Benz and Factorial are developing a solid-state battery called Solstice, expected to be ready for production by the end of the decade.
- The Solstice battery aims to extend electric vehicle range by about 80% with an energy density of 450 Watt-hours per kilogram.
- Factorial has developed a quasi-solid-state battery that is being tested by automakers, including Mercedes, and is expected to be in EVs by 2026.
- Mercedes has invested in Factorial, which raised $200 million in 2022, alongside other automakers like Stellantis and Hyundai.
- Challenges in developing solid-state batteries include poor performance in cold weather and the tendency of the battery pack to expand.
Perspectives
- Mercedes Chief Technology Officer Markus Schaefer expressed confidence in Factorial's ability to develop solid-state batteries at scale by the end of the decade, highlighting the potential for significant improvements in energy density and vehicle cost.
- Despite the advancements, there are concerns regarding the challenges of developing solid-state batteries, particularly their performance in extreme weather conditions and the physical expansion of battery packs.
