A breakthrough in solid-state battery technology has been announced with ‘first-of-its-kind’ capacity retention results.

Factorial Energy revealed the testing results of the company’s 40 Amp-hour (Ah) solid-state cell technology, with 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. The claimed results 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 aims to improve energy density, safety, charging rates and costs over existing batteries. The company’s breakthrough Factorial Electrolyte System Technology is a proprietary solid electrolyte material, which enables safe and reliable cell performance with high-voltage and high-energy density electrodes. Factorial’s drop-in battery technology also can be easily integrated into the existing lithium-ion battery manufacturing infrastructure.
