About
Factorial Energy is a Billerica, MA-based company pioneering solid-state battery technology to address the growing energy demands of eMobility, defense systems, and AI-driven robotics. Conventional lithium-ion batteries have hit a ceiling — they are heavy, capacity-limited, and pose safety concerns. Factorial's solid-state batteries push beyond these constraints, offering superior energy density, enhanced safety, and long-range performance, including a milestone 1,200+ km single-charge drive powered by its solid-state cells. The company has accumulated over 150 patents and patent applications, backed by more than a decade of dedicated research and development. Factorial's manufacturing strategy is engineered for scale: its technology is 80% drop-in compatible with existing lithium-ion production lines, dramatically lowering the barrier for automotive and industrial partners to transition. Its proprietary dry-coating process further reduces manufacturing costs and improves efficiency. Factorial partners with top-tier global automotive OEMs and has expanded into drones, robotics, and defense sectors. The company positions itself as a champion of American Technology Leadership, Economic Resilience, and domestic industrialization — making it a critical player in the U.S. energy independence and national security landscape. Factorial is targeting commercial-scale production and public market readiness, with strategic partnerships and board leadership from industry veterans like Dr. Dieter Zetsche.
