The 100% dry cathode is a novel battery manufacturing process that can eliminate all hazardous solvents in cathode coating. These solvents are not only carcinogenic but also require an energy intensive process to evaporate the chemicals in order to recycle them. In addition to dry coating, Solstice™ eliminates the need for the formation process due to its unique all-solid-state cell design. The coating and formation processes are typically the most energy intensive processes in lithium-ion battery manufacturing. Factorial’s use of the dry coating and all-solid-state chemistry innovations together lower operating costs, reduce energy consumption, and minimize battery production’s environmental impact.

“Breakthrough solid-state battery performance is only relevant if it can be scaled to a size that is viable for commercial use,” said Factorial Co-Founder and CEO Dr. Siyu Huang. “This achievement underscores our team’s technical leadership and unmatched expertise in bringing innovative battery technologies to the high standards of the automotive sector. At 40Ah capacity, our all-solid-state, Solstice™ cells demonstrate the technical maturity, process validation, and scalability required for commercial applications.”

Factorial developed the 40Ah Solstice™ cells at its advanced development center in Massachusetts utilizing custom equipment to establish an in-house dry cathode coating process. Results from lifecycle testing demonstrate that smaller prototypes have already reached over 2,000 cycles.

“The dry electrode coating process is transforming battery manufacturing, introducing significant benefits – such as improved cell performance, faster lead times, and lower costs,” said Factorial CTO and Co-Founder Alex Yu. “Factorial is a leader in advancing this novel manufacturing process for larger-sized cells, which has been a significant challenge for the rest of the market on the road to unlocking one of the most important innovations in battery manufacturing. Coupled with the long cycle life and high energy density, Factorial’s Solstice™ all-solid-state battery cell is poised to give advancements in safety, range, and cost that automakers are looking for.”

This news follows the launch of Solstice™, developed in partnership with Mercedez-Benz to complement Factorial’s industry-leading FEST® (Factorial Electrolyte System Technology). In addition to passenger vehicles, Solstice™ can be used for other applications such as energy storage, consumer electronics and commercial vehicles.
