Lionano, now operating as Factorial Energy, is a Massachusetts-based battery technology company established in 2013. Founded by PhDs, MBAs, and a distinguished electrochemistry professor from Cornell University, the company started by developing advanced materials for lithium-ion batteries. Their initial focus was creating nano-engineered electrode materials that improved battery capacity and performance while reducing costs. Since their transformation into Factorial Energy, the company has redirected its efforts toward solid-state battery development, aiming to enhance safety and efficiency in electric vehicles and energy storage systems.
Battery Technology
Factorial Energy’s technology portfolio combines their foundation in nano-engineered materials with modern solid-state battery innovations. Their original electrode materials technology increased energy capacity threefold and durability fourfold while reducing charging time by 66% compared to traditional materials. These improvements came with a 20% cost reduction and enhanced safety features.
Currently, the company concentrates on solid-state battery development, which offers significant advantages over conventional lithium-ion batteries. These solid-state systems eliminate liquid electrolytes, resulting in improved safety characteristics and higher energy density. The technology serves multiple applications, from electric vehicle powertrains to residential energy storage solutions. Their manufacturing process integrates advanced materials science with efficient production methods, enabling scalable manufacturing while maintaining consistent quality standards.
Recent Projects
As of early 2025, no public announcements about recent projects are available. The most recent documented development was the company’s $22 million Series B funding round in 2018, which supported scaling up production and global deployment of their cathode materials. This funding helped establish their manufacturing capabilities and market presence.
Investors
Factorial Energy has attracted substantial investment support throughout its development. Notable investors include Wave Equity Partners, Helios Capital Ventures, and NXT Ventures, who led the Series B funding round. The company secured $17.19 million in venture funding in February 2021, followed by a significant $200 million Series D round in January 2022. Their total funding reached $288.2 million as of mid-2023, demonstrating strong investor confidence in their technology and market potential.
