Stellantis Combines Innovative Solid-State Battery Technology with New Development Vehicle for Road Testing

Stellantis Integrates Advanced Battery Technology into Development Vehicle

Stellantis, a leading global automaker, has made a significant advancement in sustainable mobility by incorporating Factorial's cutting-edge solid-state battery cells into one of its development vehicles. This marks the first application of solid-state battery technology in an automotive setting within North America, a major milestone in the thrilling journey towards electric vehicle evolution.

The collaboration between Stellantis and Factorial has resulted in the integration of the innovative FEST® (Factorial Electrolyte System Technology) solid-state battery into a Dodge Charger Daytona development vehicle. This collaboration not only demonstrates the commitment of both companies to advancing battery technology but also sets a new standard for performance, safety, and reliability in electric vehicles (EVs).

Real-World Testing Underway

With the vehicle now equipped with the advanced battery system, road testing has begun. This comprehensive testing program is crucial for verifying the battery's performance and safety under real driving conditions. Engineers from both Stellantis and Factorial have worked collaboratively, using their expertise to ensure that the battery not only meets but exceeds automotive standards for durability and efficiency.

Ned Curic, Stellantis' Chief Engineering and Technology Officer, highlighted the importance of balancing various performance metrics in battery development. He emphasized that simply optimizing a single aspect is not effective; instead, a holistic approach that delivers tangible benefits is essential. Curic noted, “This milestone signifies our commitment to bringing solid-state batteries closer to our customers, offering the potential for longer ranges, quicker charging, and reduced costs.”

Revolutionary Battery Characteristics

The FEST® cells, which were previously validated in automotive-scale tests, boast impressive specifications, including an energy density of 375 Wh/kg and an ultra-fast charging capability that can replenish the battery from 15% to 90% in just 18 minutes. Furthermore, these batteries are designed to operate reliably in extreme temperatures, functioning safely in environments ranging from -30°C to 45°C. This level of performance is crucial for consumer acceptance and the wide adoption of electric vehicles.

Transitioning the FEST® cells from testing to an actual development vehicle involved significant engineering innovation. The Stellantis team designed a new mechanical architecture for the battery pack, seamlessly integrating the solid-state technology into the existing battery framework, thereby optimizing cell performance under routine driving conditions. This adaptation process also required modifications to the vehicle's control systems and design elements to guarantee that all automotive safety standards were met.

A Collaborative Effort for Future Innovation

Siyu Huang, CEO of Factorial, expressed excitement about the collaboration, stating, “Working with Stellantis, one of the world's leading mass-market automakers, has been an honor. Our partnership has led to the development of a full-stack approach, from cell chemistry through to pack architecture, enabling real-world testing. This milestone is not just a validation of FEST®; it's a breakthrough moment for what automotive-grade solid-state batteries can achieve.”

The successful integration of this advanced battery technology is a critical step forward in a larger demonstration program between Stellantis and Factorial. It signifies a commitment to ongoing development, calibration, and the industrial process needed for solid-state batteries for widespread automotive application.

Looking Forward

As the testing program proceeds, Stellantis aims to fine-tune the battery pack's performance and reliability, showcasing the possibilities of solid-state technology in electric vehicles. This collaboration lays the groundwork for future innovations and paves the way for vehicles that embrace this groundbreaking battery technology, meeting the needs of modern drivers looking for efficiency and sustainability.

By validating the capabilities of solid-state batteries in real-world conditions, Stellantis and Factorial are setting the stage for a new era in electric mobility, one that promises to deliver longer ranges, faster charging times, and lower production costs for a more robust electric vehicle market in the future.
