Factorial Energy Inc.

US-based Factorial Energy and Korea's SK On have signed a non-binding Memorandum of Understanding to evaluate manufacturing synergies for solid-state batteries. The partnership will assess whether SK On's global lithium-ion battery production network, which exceeds 200 GWh of annual capacity including roughly 100 GWh in the United States, can support Factorial's FEST solid-state battery technology. Factorial CEO Siyu Huang emphasized that the collaboration aligns with the company's capital-light industrialization strategy by leveraging existing manufacturing infrastructure. SK On's Head of Future Technology Ki-soo Park noted the opportunity to evaluate technical feasibility and manufacturing readiness, drawing on the company's expertise. The collaboration targets mobility and high-performance markets and marks Factorial's first manufacturing-focused partnership with a global battery producer.

Factorial Energy and SK On have signed a Memorandum of Understanding to explore the future development of solid-state battery manufacturing. The partnership will evaluate the technical feasibility and manufacturing considerations for Factorial's FEST solid-state battery technologies, leveraging SK On's global manufacturing network and pilot capabilities. SK On operates more than 200 gigawatt-hours of annual production capacity worldwide, including approximately 100 gigawatt-hours in the United States. The collaboration reflects Factorial's capital-light approach to industrialization, aiming to integrate its next-generation batteries into established manufacturing ecosystems. The MOU is non-binding except for certain customary provisions, with definitive agreements expected to follow.

Factorial Energy and Tulip Tech Group have formed a strategic partnership to accelerate commercial deployment of solid-state and lithium-metal batteries for next-generation drones. Initial customer flight testing delivered more than a 30% increase in flight range before any engineering optimization. The companies have established a commercialization framework that includes joint customer engagement and a roadmap toward volume production. Factorial's solid-state and lithium-metal platforms provide higher energy density for longer mission profiles, while Tulip brings proven UAV integration expertise and production scale, having delivered over 100,000 battery packs in a single month to more than 250 customers including NASA. The global UAV market is projected to exceed $160 billion by 2034, with battery performance seen as the defining limiter on unmanned systems.

Stellantis and Factorial have launched the first North American road testing of an electric vehicle powered by advanced solid-state battery technology. The battery, integrated into a Dodge Charger Daytona, uses Factorial's FEST system with a patented mechanical architecture for high energy density and ultra-fast charging. The ongoing test program aims to tune system performance, safety, and durability, marking a shift from laboratory validation to real-world application. The project demonstrates compatibility with existing lithium-ion manufacturing processes, providing a path toward scaling high-performance, cost-effective solid-state batteries for future mass-market vehicles.
