In a significant stride towards revolutionizing electric vehicle (EV) technology, Stellantis, the global automotive giant behind iconic brands like Jeep, Ram, and Dodge, has officially initiated real-world testing for an experimental semi-solid-state battery. This pioneering energy storage unit is currently integrated into a Dodge Charger Daytona EV prototype, marking a critical phase in its development.

The multinational corporation, which oversees a portfolio of 14 automotive marques, announced on Thursday that the rigorous testing aims to evaluate the viability and performance of these advanced batteries under authentic driving and charging scenarios. This move positions Stellantis at the forefront of exploring next-generation battery solutions, crucial for the broader adoption and enhanced capabilities of electric vehicles.

Pioneering Battery Technology in Action

The specific Dodge Charger EV undergoing these evaluations is outfitted with a sophisticated semi-solid-state battery pack developed by Factorial Energy, a Massachusetts-based startup renowned for its innovative work in battery chemistry. This partnership is central to Stellantis’ commitment to push the boundaries of electric mobility.

Engineers and technicians are meticulously fine-tuning and validating the battery pack’s inherent safety features, overall performance metrics, and long-term reliability. These tests are conducted across a diverse range of actual charging and driving conditions, providing invaluable data for future commercial applications.

Ned Curic, Stellantis’ chief engineering and technology officer, underscored the transformative potential of this development. He stated, “This milestone shows we are bringing solid-state batteries closer to our customers with the potential for longer range, faster charging, and lower costs.” His comments highlight the strategic importance of this technology in shaping the future electric vehicle landscape.

Understanding Semi-Solid-State Batteries

While the promise of solid-state batteries has long captivated the automotive industry, their development and large-scale manufacturing have proven notoriously challenging. Traditional lithium-ion batteries, despite continuous improvements and well-established supply chains, inherently face limitations in energy density, charging speed, and safety characteristics.

Semi-solid-state batteries represent a crucial intermediary step, addressing some of these challenges. Unlike conventional lithium-ion batteries that use a liquid electrolyte, or true solid-state batteries that use an entirely solid electrolyte, semi-solid-state variants typically incorporate a gel-like or polymer-based electrolyte. This hybrid approach aims to combine the benefits of both technologies, offering enhanced safety and performance without the full manufacturing complexities of all-solid-state designs.

Factorial’s innovative FEST cell, central to the Dodge Charger EV prototype, exemplifies this advancement. It boasts a semi-solid-state chemistry with an impressive energy density of 375 watt-hours per kilogram (Wh/kg). This figure stands in stark contrast to conventional lithium-ion batteries, which typically fall within the 200-300 Wh/kg range, signifying a substantial leap in energy storage capability.

Performance Benchmarks and Real-World Advantages

The performance metrics of Factorial’s battery are particularly compelling. Stellantis reports that the pack is engineered to charge from 15% to 90% capacity in a mere 18 minutes. This represents a significant improvement over the current lithium-ion pack found in the Dodge Daytona, which requires approximately 30 minutes to charge from 10% to 80%.

Furthermore, the battery demonstrates robust operational capabilities across a broad temperature spectrum, functioning effectively from -22 degrees Fahrenheit (-30 degrees Celsius) to 113 degrees Fahrenheit (45 degrees Celsius). This wide temperature tolerance is critical for electric vehicles operating in diverse global climates, addressing a common concern for EV owners in extreme weather conditions.

Siyu Huang, CEO of Factorial, emphasized the collaborative effort inherent in this progress. “Real-world road testing is exactly the kind of deep full-stack collaboration that solid-state has always required,” Huang stated, highlighting the necessity of comprehensive testing to bring such advanced technologies to fruition.

The Road Ahead: From Semi-Solid to All-Solid-State

The integration of Factorial’s semi-solid-state cells into the Dodge Charger EV prototype utilizes a new, patented mechanical architecture. This design is specifically engineered by Stellantis to extract maximum performance from these advanced cells, optimizing their efficiency and longevity within the vehicle’s existing framework.

Factorial has previously communicated that the insights garnered from these semi-solid-state tests will directly inform the development of its forthcoming all-solid-state Solstice battery. This iterative approach underscores the importance of the current real-world evaluations, making them equally crucial for Factorial’s long-term battery innovation roadmap as they are for Stellantis’ immediate EV advancements.

This is not the first instance of Factorial’s batteries being deployed outside laboratory settings. Last year, semi-solid-state cells from Factorial were successfully installed in a Mercedes-Benz EQS prototype. During a cross-country journey across Europe, this EQS notably covered an impressive 749 miles on a single charge, with an additional 85 miles of range still remaining, demonstrating the significant range potential of this nascent technology.

A Global Race for Battery Dominance

The pursuit of next-generation battery technology extends far beyond Stellantis and Factorial, reflecting a global race among leading automakers and tech firms. The industry wide push towards more efficient, safer, and faster-charging electric vehicle batteries is intensifying, with various companies exploring different avenues.

Last year, BMW, another major player in the luxury automotive segment, initiated testing of all-solid-state cells from Colorado-based startup Solid Power in a prototype i7. The German automaker has also engaged Samsung SDI, a prominent battery manufacturer, to assist in the development and validation of Solid Power’s advanced cells.

Japanese automotive giant Toyota has its own dedicated solid-state program underway, signaling its deep commitment to this revolutionary technology. Concurrently, several prominent Chinese automakers, including BYD, Nio, and MG Motor, are actively investing in and developing their own solid-state battery solutions, indicating a widespread global consensus on the importance of this technological frontier for sustainable mobility.

The ongoing real-world tests of the Dodge Charger EV with Factorial’s semi-solid-state battery represent a tangible step forward in this competitive and rapidly evolving landscape. Success in these evaluations could significantly accelerate the commercialization of more efficient and sustainable electric vehicles, bringing the promise of next-generation battery performance closer to consumers.
