Factorial Energy announces impressive capacity retention testing results

1 min read

US company, Factorial Energy, has announced what it is describing as breakthrough capacity retention testing results for its first-of-its-kind 40 Amp-hour (Ah) solid-state cell technology.

According to the company, an initial round of cell cycle behaviour testing at 25 Celsius demonstrated a 97.3% capacity retention rate after 675 cycles.

Solid-state batteries have struggled to scale up cell capacity and Factorial’s successful cell performance results suggests that it is in a strong position to address the market for solid-state battery electric vehicle (EV) applications. The testing marks a major performance milestone for the company's technology and it is currently in discussions with several car manufacturers 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 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 emerged from stealth mode in Q2 2021 and is developing solid-state battery technology that can improve energy density, safety, charging rates and costs over existing battery technologies.

The company’s 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.
