Factorial Inc., a leader in solid-state battery technology, announced today the successful scaling of its Solstice™ all-solid-state battery cells to a 40Ah capacity. These A-sample cells, designed for automotive applications, are produced using an innovative dry cathode coating process, showcasing the impressive energy density the company unveiled in September. This achievement marks a key step toward making the technology available for various electric mobility industries.
The new 100% dry cathode process eliminates the use of hazardous solvents in cathode coating, which are both carcinogenic and energy-intensive to recycle. In addition to eliminating solvents, the Solstice™ cells’ all-solid-state design removes the need for the energy-consuming formation process typically required in lithium-ion battery manufacturing. By combining dry coating with solid-state chemistry, Factorial reduces operating costs, lowers energy consumption, and minimizes the environmental impact of battery production.
“Breakthrough solid-state battery performance is only valuable when it can be scaled for commercial use,” said Dr. Siyu Huang, Factorial’s Co-Founder and CEO. “This milestone demonstrates our team’s technical leadership and our ability to meet the high standards of the automotive industry. At 40Ah, our Solstice™ cells show the technical maturity, process validation, and scalability needed for real-world applications.”
Factorial developed the 40Ah Solstice™ cells at its advanced development center in Massachusetts, using custom equipment to establish an in-house dry cathode coating process. Early lifecycle testing indicates that smaller prototypes have already achieved over 2,000 charge cycles.
“The dry electrode coating process is revolutionizing battery manufacturing by offering improved performance, faster lead times, and lower costs,” said Alex Yu, Factorial’s CTO and Co-Founder. “As a leader in advancing this innovative process for larger cells, Factorial is overcoming challenges faced by the industry to unlock one of the most significant innovations in battery manufacturing. With long cycle life, high energy density, and enhanced safety, our Solstice™ all-solid-state battery cells are poised to deliver the advancements automakers need in terms of range, safety, and cost.”
