Stellantis validates Factorial Energy solid-state battery cells

April 24 (Reuters) - Carmaker Stellantis STLAM.MI announced on Thursday the successful validation of U.S. startup Factorial Energy's automotive-sized solid-state battery cells with FEST (Factorial Electrolyte System Technology).

Stellantis invested 75 million euros ($85.34 million) in Factorial Energy in 2021, and will introduce the company's solid-state batteries into a demonstration fleet by 2026 as announced last year.

Unlike traditional lithium-ion batteries, solid-state batteries offer higher energy density and faster charging, allowing a charge from 15% to over 90% in just 18 minutes at room temperature, according to the joint statement from Stellantis and Factorial Energy.
