Stellantis validates solid-state battery that charges 90% in 18 minutes, plans 2026 debut (X @FactorialEnergy)
Stellantis has announced the validation of its new solid-state battery cells for electric vehicles, developed in partnership with U.S.-based Factorial Energy.
These batteries promise significant advances over traditional lithium-ion technology, offering higher energy density and much faster charging times — reaching over 90% charge in just 18 minutes at room temperature.
The new cells have an energy density of 375 Wh/kg and can endure more than 600 cycles, while delivering high power and operating between -30°C and 45°C, thanks to an electrolyte formula developed using artificial intelligence. This set of innovations aims to meet higher performance demands and improve reliability under various climate conditions, overcoming previous solid-state battery limitations.
Stellantis and Factorial are currently working to optimize battery pack architecture to reduce weight, increase range, and make electric vehicles more sustainable and accessible.
The technology is expected to debut in a demonstration fleet by 2026, aligning with Stellantis’ $75 million investment in the strategic partnership established in 2021.
