Solid-state EV batteries, considered the 'holy grail' of battery tech, are making progress towards reality in the US. Factorial Energy, a US-based company, is at the forefront of solid-state EV battery development and has partnered with major automotive brands to advance this technology.
The latest milestone achieved by Factorial is the launch of its first commercial solid-state battery program in the US through a collaboration with Karma Automotive. This partnership will see Factorial supply its FEST quasi-solid-state batteries to be used in Karma's upcoming lineup of ultra-luxury electric vehicles, including the highly anticipated Karma Kaveya super-coupe EV.

Factorial's technology has already demonstrated real-world results, including a record-breaking 745-mile drive by Mercedes-Benz in a modified EQS equipped with its solid-state battery cells. The partnership between Factorial and Karma will validate the solid-state technology in production passenger vehicles, paving the way for further development and adoption of this innovative technology.
This collaboration also highlights the growing importance of the US as a hub for next-gen battery tech, with Factorial's plans to list on the Nasdaq exchange through a business merger providing a significant boost to the company's growth prospects.
The partnership between Factorial and Karma is a significant step forward for solid-state EV batteries, demonstrating the potential for this technology to deliver improved range, reduced weight, and increased compatibility with existing manufacturing equipment. As the US continues to invest in next-gen battery tech, we can expect to see more innovative partnerships like this one drive progress towards a more sustainable transportation future.
