Factorial unveiled its first 100 Amp-Hour (Ah) solid-state battery cell at CES 2023 in the Stellantis exhibit. This cell is the result of the joint development agreement between Factorial and Stellantis, which was announced in November 2021. The collaboration aims to bring solid-state battery technology to electric vehicles.
Factorial has already successfully developed automotive-sized cells with a capacity of 40 Ah, and is now introducing even larger cells to meet the performance requirements of their top global automotive OEM partners.
“Factorial is excited to showcase our large format solid battery cells in an automotive battery pack concept application at this year’s CES,” said Siyu Huang, CEO of Factorial. “Solid-state battery technology is rapidly advancing, and Factorial is proud to be at the forefront of cell development. We are immensely grateful to Stellantis for their close collaboration and partnership in bringing our technology to market.”
“We are thrilled to be partnering with Factorial, as part of our Dare Forward 2030 strategic plan, to develop a proprietary technology that uses less cobalt,” said Carlos Tavares, Stellantis CEO. “The solid-state battery is expected to deliver up to 30% higher energy density compared to conventional lithium ion, which could enable an even longer driving range or less weight. ‘More with less’ is the way to lead the way the world moves.”
Factorial Energy, based in Woburn, Massachusetts, has developed solid-state batteries that offer up to 50% longer range per charge, improved safety, and cost competitiveness with traditional lithium-ion batteries. Their proprietary FEST™ (Factorial Electrolyte System Technology) uses a quasi-solid electrolyte material that allows for safe and reliable cell performance with high-capacity cathode and anode materials.
FEST™’s electrolyte can be used in 100Ah cells, operates at room temperature, and can be produced using most existing lithium-ion battery manufacturing equipment. The company has received strategic investments and entered into joint collaboration agreements with Mercedes-Benz, Stellantis, and Hyundai Motor Company.
