Factorial Energy announces breakthrough capacity retention results for 40Ah solid-state battery

Factorial Energy, Woburn, MA, United States, has announced breakthrough capacity retention testing results of the company’s first-of-its-kind 40 Amp-hour (Ah) solid-state cell technology. The company’s initial round of cell cycle behavior testing at 25 degrees Celsius demonstrated a 97.3% capacity retention rate after 675 cycles.

Solid-state batteries have struggled in the past to scale up cell capacity. Factorial’s successful cell performance results prove that the company has overcome this challenge and is leading the field in solid-state battery electric vehicle (EV) application. The testing marks a major performance milestone for Factorial’s technology as the company speeds to market and continues discussions with several automakers on supporting the research and manufacturing of EV battery cells.

“Factorial’s initial cycle testing behavior proves that our solid-state battery technology is in advanced stages of development, offers superior levels of performance and is positioned to make a major impact on the battery market. Scaling up cell capacity has been a major impediment for solid-state batteries and we are thrilled that our proprietary technology has broken through this critical performance barrier,” said Factorial Energy CEO Siyu Huang. “We are proud to be the first company to announce a 40 Ah solid-state cell performing at room temperature, and we’re working closely with our global leading strategic partnerships to bring the technology to the electric vehicle market.”

Factorial is developing solid-state battery technology that can improve energy density, safety, charging rates and costs over existing batteries. The company’s breakthrough Factorial Electrolyte System Technology™ (FEST™) is a proprietary solid electrolyte material, which enables safe and reliable cell performance with high-voltage and high-energy density electrodes. Unlike any others on the market, Factorial’s drop-in battery technology also can be easily integrated into the existing lithium-ion battery manufacturing infrastructure.

Factorial emerged from stealth mode in Q2 2021 and has assembled a powerhouse leadership team. Former Chairman and CEO of Panasonic Corporation of North America Joe Taylor serves as Factorial’s executive chairman. Dieter Zetsche, the former chairman of the Board of Management of Daimler AG and Head of Mercedes-Benz; Mark Fields, former Ford Motor Company CEO; and Harry Wilson, former senior advisor to the Obama Administration’s Presidential Task Force on the Auto Industry, serve on Factorial’s advisory board.
