Stellantis will test solid-state battery cells from Massachusetts-based Factorial in a fleet of Dodge Charger Daytona electric vehicles from 2026the two companies announced on Wednesday.
The test fleet will “enable the validation of Factorial's technology and the evaluation of its performance in real-world driving conditions,” the companies said. It will also help Stellantis measure whether solid-state factorial cells can be integrated into a larger EV-focused STLA—which supports the Charger, Jeep Wagoneer S, and other future models—at a commercial scale.

It is yet another step in the commercialization of Factorial's battery technology, which the company has been developing steadily over the past few years. Factorial began supplying test cells to automakers in 2022. The following year, Factorial opened what it called the largest EV battery plant in the US however in the suburbs of Boston.
Stellantis invested $75 millionn eFactorial in 2021. Other car manufacturing investors include Hyundai and Mercedes-Benz. Earlier this year, Factorial announced that its Solstice solid-state cell developed in collaboration with Mercedes could improve EV range up to 80% by using high energy density.

Some automakers are also funding solid-state battery technology. Volkswagen is partnering with QuantumScape, while Nissan and Toyota are developing in-house development programs. Earlier this year, Toyota confirmed plans to start to produce solid-state cells in 2026 or soon after, although it is possible for small amounts of low-volume EVs.
Meanwhile, the Daytona Charger is expected to arrive at dealerships before the end of the year with a base price of $61,590 for the entry-level R/T model. It is also expected to return a range of 317 miles with a 100.5-kwh battery (93.5-kwh usable) combined with conventional lithium-ion cells.
