>After completing its business merger with Cartesian Growth Corp III (A SPAC company) on June 8, 2026, Factorial began trading on **Nasdaq under the ticker symbols “FAC” and “FACWW.”** The merger is expected to be worth $1.3 billion.
Its solid-state batteries have already proven capable of delivering over **745 miles (1,200 km)** of real-world driving range. Now, US-based solid-state battery maker Factorial Energy is tapping into public markets to fund its next phase of growth.
“We built Factorial to solve one of the hardest problems in energy – making solid-state real at scale,” CEO Siyu Huang said after announcing the company is now a publicly listed company.
Last September, Mercedes-Benz drove a modified EQS over 745 miles (1,200 km) on a single charge, using solid-state battery cells from Factorial. According to Mercedes’ tech boss, Markus Schäfer, Factorial’s new battery tech could be a true “gamechanger” for electric vehicles. Mercedes said the usable energy of the solid-state battery increased by 25%, while the weight and size were roughly the same as those of a standard EQS.
Factorial has partnerships with Mercedes-Benz, Hyundai, Kia, and Stellantis to develop and bring the next generation of solid-state batteries to market.
Beyond EVs, Factorial plans to supply its solid-state battery cells to other industries, including defense, aerospace, and robotics. Factorial said it will receive around $110 million in gross proceeds to support the continued commercialization of its next-generation batteries for defense & aerospace, hyperscale data centers, and e-mobility.”
