Solid-state EV batteries<\/a> are now being tested on the road in North America for the first time, promising longer range, faster charging, and lower costs.<\/p>\n

Factorial, Stellantis test solid-state EV batteries in real life<\/p>\n

Jeep maker Stellantis and US-based Factorial Energy officially began testing the advanced new battery tech on the road, marking the first time solid-state batteries have been integrated into an EV in North America.<\/p>\n

Factorial\u2019s FEST (Factorial Electrolyte System Technology<\/a>) solid-state battery cells were used to power a Dodge Charger Daytona development vehicle.<\/p>\n

The milestone comes after Stellantis and Factorial validated that 77Ah FEST cells achieved an energy density<\/a> of 375 Wh\/kg with over 600 cycles last April. <\/p>\n

Factorial\u2019s advanced solid-state battery cells also proved ultra-fast charging from 15% to 90% in just 18 minutes, and maintained performance in extreme temperatures ranging from -22\u00b0F to 113\u00b0F (-30\u00b0C to 45\u00b0C). Plus, the cells deliver a discharge rate of up to 4C.<\/p>\n

Moving the new battery tech from the lab to the real world wasn\u2019t easy. Stellantis said transitioning the cells into a development vehicle \u201cdemanded advanced engineering solutions\u201d from both companies.<\/p>\n

Factorials FEST solid-state battery cells were integrated into Stellantis\u2019 STLA Large platform, while engineers modified the control systems and pack design to optimize safety and performance.<\/p>\n

With the battery pack now complete, Stellantis and Factorial have begun road testing for the first time in North America.<\/p>\n

\u201cWhat we have built together, from cell chemistry to pack architecture to enable real-world road testing, is exactly the kind of deep, full-stack collaboration that solid-state has always required,\u201d Factorial\u2019s CEO, Siyu Huang, said.<\/p>\n

He added that \u201cThis milestone doesn\u2019t just validate FEST; it sets a new bar for what automotive-grade solid-state batteries can deliver and supports the development of future vehicles designed to meet the evolving needs of drivers.\u201d<\/p>\n

Factorial is working with several major automakers, including Mercedes-Benz, Hyundai, Kia, and Stellantis, to commercialize solid-state EV batteries.<\/p>\n

Last September, Mercedes-Benz drove a modified EQS\u00a0over 745 miles<\/a>\u00a0(1,200 km) using Factorial\u2019s solid-state battery cells. Mercedes\u2019 tech boss, Markus Sch\u00e4fer, said Factorial\u2019s battery tech could be a real \u201cgamechanger\u201d for EVs.<\/p>\n

Beyond the automotive industry, Factorial plans to expand the battery tech to other segments, such as robotics, aerospace, and defense.<\/p>\n

Factorial said its solid-state battery cells deliver a 50% improvement in driving range, offering over 600 miles on a single charge. Earlier this week, Factorial began trading on Nasdaq<\/a> under the ticker symbol \u201cFAC\u201d following a business merger with Cartesian Growth Corp III (a SPAC). The merger is worth about $1.3 billion, and Factorial will receive roughly $110 million as it works to commercialize the next generation of batteries.<\/p>\n
