Stellantis, the parent company of iconic brands like Jeep, Dodge, and Ram, has made a significant breakthrough in electric vehicle (EV) technology with its solid-state batteries, capable of fast charging in just 18 minutes. This achievement is the result of a partnership with startup Factorial, which has developed a new battery design that balances high density with rapid charging speeds.

The new batteries, dubbed Factorial Electrolyte System Technology (FEST), use a lithium-metal anode, quasi-solid electrolyte, and high-capacity cathode to achieve an energy density of 375Wh/kg with over 600 charging cycles. This milestone marks a significant improvement over traditional lithium-ion batteries, which have been the standard in the EV industry.

The implications of this technology are far-reaching, with the potential to revolutionize the EV landscape. Faster charging times will make long-distance travel more practical, reducing range anxiety and increasing the appeal of EVs to a wider audience. Additionally, the higher power output of these batteries, with discharge rates up to 4C, will enable greater EV performance, making them more competitive with their gas-powered counterparts.

Factorial's technology has also demonstrated its ability to perform well in a variety of weather conditions, including extreme cold and heat, making it a reliable choice for EV manufacturers. The company's CEO, Siyu Huang, noted that "battery development is about compromise," and that achieving a balance between high energy density, cycle life, fast charging, and safety in an automotive-sized battery is a breakthrough.

Stellantis is not the only company making progress in solid-state battery technology. Hyundai and Mercedes, both investors in Factorial, are also working on similar projects. Honda plans to introduce solid-state EVs in the latter half of the decade, while Toyota aims to mass-produce solid-state batteries that enable over 621 miles of range by 2028. Volkswagen is also working with Quantum State, which has recently achieved its own milestone in solid-state battery development.

However, the US is in danger of being left behind by China, where companies like CATL and BYD are pushing the boundaries of EV technology. These companies have teased new tech that allows EVs to fast charge in just five minutes, a significant leap ahead of the current state of the art.

As the EV industry continues to evolve, breakthroughs like Stellantis' solid-state batteries will play a crucial role in shaping the future of transportation. With its partnership with Factorial, Stellantis is well-positioned to take advantage of this emerging technology, and its demonstrator fleet, set to debut in 2026, will be an important milestone in the development of solid-state batteries for automotive use.

As the world moves towards a more sustainable and environmentally friendly transportation system, innovations like Stellantis' solid-state batteries will be essential in driving progress and making EVs a viable option for consumers.
