Factorial Inc., a leading innovator in solid-state battery technology, has successfully scaled its first Solstice™ all-solid-state battery cells to a 40Ah capacity. This milestone showcases the technical maturity of automotive-grade A-sample cells produced using Factorial’s innovative dry cathode coating process. These cells deliver the high energy density previously announced, marking significant progress toward commercial availability for various electric mobility industries.
Revolutionizing Battery Manufacturing with Dry Coating Technology
The 100% dry cathode coating process represents a paradigm shift in battery production. Unlike conventional methods that rely on carcinogenic solvents and energy-intensive recycling processes, this novel technique eliminates hazardous chemicals and significantly reduces energy consumption. Additionally, Factorial’s all-solid-state design does away with the formation process, one of the most resource-heavy stages in traditional lithium-ion battery manufacturing. This dual innovation cuts operating costs, minimizes environmental impact, and positions Factorial as a leader in sustainable battery technology.
Advancing Commercial Viability and Performance
Dr. Siyu Huang, Factorial’s Co-Founder and CEO, emphasized the importance of scalability:
“Breakthrough solid-state battery performance is only relevant if it can be scaled to a size viable for commercial use. Our 40Ah Solstice™ cells demonstrate the technical and process advancements necessary to meet the stringent requirements of the automotive sector.”
Developed at Factorial’s advanced Massachusetts facility, these batteries underwent rigorous lifecycle testing. Preliminary results indicate smaller prototypes achieved over 2,000 cycles, reinforcing the durability and reliability of this cutting-edge technology.
Advantages in Safety, Cost, and Efficiency
Factorial CTO and Co-Founder Alex Yu highlighted the transformative potential of the dry cathode coating process:
“This innovation improves cell performance, accelerates production timelines, and lowers costs. Coupled with our Solstice™ cells’ long cycle life and high energy density, this breakthrough meets automakers’ demands for enhanced safety, range, and affordability.”
