Factorial Inc. (“Factorial”), the US-based solid-state battery developer pushing the boundaries of next-generation energy storage solutions, and Cartesian Growth Corporation III (“Cartesian III”) announced that Factorial has entered into a Memorandum of Understanding (MOU) for a strategic manufacturing partnership with Philenergy, a leading battery equipment and infrastructure solutions provider in Korea. The partnership aims to facilitate the mass production of Factorial’s Solstice all-solid-state battery technology.
Through the collaboration, the companies will evaluate the integration of Philenergy’s advanced manufacturing infrastructure and established battery production supply chain with Factorial’s proprietary solid-state battery architecture. The joint effort is intended to bridge the gap between breakthrough laboratory innovation and repeatable, large-scale commercial manufacturing.
“The companies that win in next-generation batteries won’t just have breakthrough technology – they’ll have production partners experienced in battery manufacturing and capable of delivering at scale,” said Siyu Huang, CEO of Factorial. “Philenergy brings proven production expertise and infrastructure that matches the ambition of Solstice™.”

“Factorial has established itself as a true technology leader in the solid-state battery space, with deep materials expertise and a clear path toward scalable commercialization,” said Kim Kwang-il, CEO of Philenergy. “The Solstice™ platform represents one of the most advanced solid-state architectures in the industry, combining high energy density with manufacturability. We are proud to support Factorial’s vision and contribute our manufacturing capabilities to help bring this breakthrough technology to global markets.”
Solstice™ is engineered to provide capabilities that go beyond the traditional lithium-ion battery capabilities, offering up to 80% greater energy density with the ability to function within a stable temperature range of 90°C. The Solstice™ platform has the potential to unlock new applications in the electric mobility, aerospace, and energy sectors due to its ability to operate within a much higher temperature range than current battery systems.
In addition to its performance, the Solstice™ platform is designed with manufacturability and sustainability in mind. The technology brings a faster formation process and a solvent-free process with a novel dry-cathode design. This design cuts down on energy-intensive manufacturing processes, reduces the complexity of production, and significantly lowers the environmental footprint of conventional lithium-ion battery manufacturing.
