Major Milestone Paves the Way for Next-Gen EV Technology
Stellantis and Factorial Energy have reached a significant milestone in the development of next-generation electric vehicle batteries. By successfully validating automotive-sized solid-state battery cells using Factorial’s FEST® technology, the partnership has taken a crucial step toward commercializing this innovative energy solution. Unlike conventional lithium-ion batteries, these solid-state cells deliver higher energy density, faster charging, and improved safety. This breakthrough marks a major move in the automotive industry’s shift toward more efficient, cost-effective, and environmentally friendly electric vehicles.
High Performance Meets Practical Application
The validated FEST® cells demonstrated an impressive energy density of 375Wh/kg and a capacity of 77Ah, enabling over 600 charge cycles. These batteries reduce EV charging times dramatically—charging from 15% to 90% in only 18 minutes at room temperature. They also support high power output with discharge rates up to 4C, addressing the demands of modern electric vehicles. With temperature stability from -30°C to 45°C, these batteries can perform reliably in a variety of climates, solving a long-standing limitation in solid-state battery development.
Seamless Integration for Better Vehicle Performance
Stellantis and Factorial are actively refining battery pack design to maximize efficiency and reduce weight. This optimization directly translates into increased driving range and lower production costs—key factors in making electric vehicles more accessible and sustainable. Factorial’s advanced electrolyte formulation, supported by AI-driven engineering tools, enhances battery performance across all conditions. The goal is clear: integrate lighter, faster-charging, and more powerful batteries seamlessly into next-gen vehicles.
Looking Ahead: Commercial Deployment on the Horizon
This milestone builds on Stellantis’ $75 million investment in Factorial Energy made in 2021. The collaboration is now advancing toward integrating these solid-state batteries into a demonstration EV fleet by 2026. This phase will allow for further testing in real-world conditions, setting the stage for full-scale commercial deployment. As both companies continue to innovate, this achievement moves the automotive world one step closer to mainstream adoption of advanced, solid-state electric vehicle technology.
