      Dodge and Factorial have commenced tests on solid-state batteries, with production expected to start after 2028.

      These batteries promise quicker charging, increased energy density, and enhanced range.

      Factorial's technology also ensures better performance even in extremely cold conditions.

      Stellantis, particularly its Dodge brand, is in dire need of a success right now. Solid-state batteries represent a promising new technology that could offer the necessary boost. Factorial, the company developing these advanced batteries, has partnered with Dodge to conduct real-world tests. If everything goes as planned, Dodge might introduce vehicles featuring this technology between 2028 and 2032.

      The two companies have collaborated since 2021, but this is the first instance where Dodge will evaluate prototypes on public roads. Starting in 2026, they will launch a fleet of Chargers fitted with Factorial's solid-state batteries to refine and resolve any issues.

      A Major Milestone for Cell Performance

      “What happened with Stellantis is a crucial milestone for cell performance validation,” stated Factorial CEO Siyu Huang to Autonews. “It’s not solely about enhanced energy density, but also about cycle life and rapid charging. Above all, this is the first comprehensive validation shared by automakers.” The potential advantages are extensive and crucial for the electric vehicle movement.

      For example, solid-state batteries enable speedier charging. The batteries being tested by Dodge can deliver 375 watt-hours per kilogram and can charge from 15 percent to 90 percent in only 18 minutes. Additionally, they have a higher energy density, which translates to increased range compared to traditional batteries.

      Lighter Batteries, Enhanced Range, and Cold Weather Performance

      Conversely, an automaker could theoretically provide a smaller, lighter battery that still achieves the range typical of today’s EVs. Factorial has also made strides in solid-state battery technology for cold weather. Importantly, these batteries are safer as they utilize a solid, non-flammable electrolyte. “We can deliver strong performance not just at room temperature but also at conditions as low as -30 degrees Celsius. This capability was not achievable until just a few months ago,” she mentioned.

      Additionally, Factorial is not exclusively collaborating with Stellantis; it is also engaged with Kia, Hyundai, and Mercedes-Benz. The German automaker is currently testing these batteries on the road as of February this year.

      In summary, all these automakers will gain advantages as solid-state batteries become standard. Increased range, improved charging speeds, and potential weight savings are all exciting prospects. We hope the testing proceeds successfully and that we witness this technology mature sooner rather than later.
