- Factorial Energy began trading on Nasdaq under "FAC" and "FACWW" on June 8, 2026, after completing a business merger with SPAC Cartesian Growth Corp III valued at $1.3 billion.
- Factorial will receive approximately $110 million in gross proceeds to commercialize solid-state batteries for e-mobility, defense & aerospace, and hyperscale data centers.
- Mercedes-Benz drove a modified EQS over 745 miles (1,200 km) on a single charge using Factorial's solid-state cells last September, with Mercedes tech boss Markus Schäfer calling the tech a potential "gamechanger."
- Stellantis verified Factorial's 77 Ah solid-state cells at 375 Wh/kg energy density over 600+ cycles, cutting charging time from 10% to over 90% in 18 minutes.
- Factorial's Fest battery pack is roughly one-third the size of a traditional Li-ion pack and 40% lighter (580 lbs vs 800 lbs), delivering 50% longer driving range exceeding 600 miles.
- Factorial has development partnerships with Mercedes-Benz, Hyundai, Kia, and Stellantis, and earlier this year launched the first US commercial solid-state battery program with Karma Automotive.
- CEO Siyu Huang told the New York Times in December that Factorial's batteries could be powering EVs as soon as 2027.
Why it matters: Factorial's Nasdaq debut unlocks $110 million in public capital to scale a solid-state battery technology already validated by four major automaker partners and a 745-mile real-world Mercedes test. The Stellantis-verified 375 Wh/kg energy density and 18-minute fast-charge to 90% represent concrete specs that differentiate Factorial from lab-stage solid-state competitors, with production EVs targeted for 2027.
