BOSTON, massachusetts – In early January, Siyu Huang, CEO of Factorial Energy, received a succinct but significant text message: “Wheels turning.” The message included a brief video depicting a car on rollers within a testing facility.
While seemingly unremarkable to the untrained eye, the video represented a major milestone for Huang and her team at Factorial Energy. They have dedicated years to developing a solid-state battery, a technology poised to potentially revolutionize the electric vehicle (EV) industry.
The Promise of Solid-State Batteries
Huang, along with her husband, Alex Yu, and their colleagues, believe this new battery technology could reshape consumer perceptions of EVs, provide a competitive edge for the United States and Europe against China, and contribute significantly to environmental sustainability.

Factorial Energy is among numerous companies striving to create batteries that charge faster,offer extended range,and reduce the cost and complexity of electric vehicles. Given that transportation is a leading contributor to global greenhouse gas emissions, advancements in EV battery technology are crucial in combating climate change and improving urban air quality.
Mercedes-Benz’s Validation
The video Huang received came from Uwe Keller, head of battery growth at Mercedes-Benz, a company that has invested in and collaborated with Factorial Energy. The clip showcased a Mercedes sedan, equipped with factorial’s solid-state battery, undergoing testing at a research lab near Stuttgart, Germany. The accomplished movement of the vehicle’s wheels marked a significant step forward.
This achievement stems from research initiated during Huang and Yu’s graduate studies at Cornell university. Until recently, their work had been confined to laboratory settings. Huang expressed excitement about seeing their innovation applied in a real-world scenario.
The Road Ahead
Despite the progress, challenges remain. The Mercedes test vehicle had not yet been road-tested, a crucial step in validating the technology’s durability and performance. While many companies have developed solid-state battery prototypes, few, if any, American or European automakers have publicly demonstrated the technology’s ability to withstand the rigors of real-world driving conditions.
Keller proposed the road test to Huang in late 2023. “We are car people,” Keller said. “We believe in things that really move.”

Huang’s Leadership Style
Huang’s approach contrasts with the demanding culture often associated with Silicon Valley. She prioritizes a healthy work-life balance, stating, “Having a clear mind to make the right decision is more crucial than the amount of hours you work.”
Her office in Billerica, overlooking a wooded area, reflects a practical and focused approach. The space is minimally decorated, with technical books from a previous tenant lining a simple bookshelf. Her doctorate in chemistry and MBA diplomas from Cornell University hang on the wall.
From China to Cornell
Huang’s interest in environmental issues began during her childhood in Nanjing, China, where she participated in a program focused on collecting environmental data. This experience sparked her interest in chemistry and raised her awareness of the impact of vehicular emissions and industrial pollution. “We need to create a healthier planet for human beings,” she recalls realizing.
While studying chemistry at the University of Xiamen, she discovered a Swedish exchange program. After two years in Sweden, she and Alex, her longtime acquaintance from China, were accepted into doctoral programs in chemistry at Cornell University. They arrived in Ithaca, New York, in 2009. Today, both are U.S. citizens.
Cornell Roots
“They were star students,” said Héctor Abruña,a Cornell professor known for his electrochemistry research. He still keeps a photo of himself with Yu and Huang in their graduation robes.
Based on an idea developed in abruña’s lab and with initial funding from New York State, Yu and Huang founded what would become Factorial Energy while huang was completing her business studies.
“They are extremely dedicated and extremely shining,” said Abruña, who continues to advise Factorial.”direct. Zero nonsense.”
Yu serves as Factorial’s Chief Technology Officer.Huang is private about her personal life.
Focus on Solid-State
Initially, the company focused on improving battery materials for energy storage. However,a 2021 investment from Mercedes-Benz shifted the company’s focus to solid-state battery technology.
Solid-state batteries replace the flammable liquid electrolyte found in conventional lithium-ion batteries with a solid or gel-like electrolyte, enhancing safety. This also allows for greater energy density and faster charging times.
A fully functional solid-state battery could significantly improve the performance and safety of electric vehicles, potentially accelerating their adoption and contributing to a more enduring transportation future.
Solid-State Battery Breakthrough: Q&A with Factorial Energy and mercedes-Benz
The electric vehicle (EV) industry is constantly evolving,with battery technology at the forefront of innovation. Recently, Factorial Energy and Mercedes-Benz achieved a meaningful milestone, sparking interest and excitement across the automotive world. Let’s dive into the details with a Q&A session.
