Dodge Charger Daytona EV to Feature Solid-State Batteries

As the automotive world eagerly anticipates the arrival of the Dodge Charger Daytona EV, Stellantis is making bold moves to enhance the future of electric vehicles (EVs). Among the most intriguing developments is the introduction of solid-state battery technology, a next-gen advancement that could revolutionize the performance and safety of EVs. While there’s plenty of excitement around the potential of this technology, there are also some caveats. Let’s dive into what this means for the Charger Daytona and the future of electric mobility.

What is Solid-State Battery Technology?

If you’re unfamiliar with the term “solid-state,” let’s break it down. Traditional EVs rely on lithium-ion batteries that use a liquid electrolyte to transport lithium ions between the positive and negative electrodes. While these batteries have become the standard due to their efficiency and widespread availability, they have several drawbacks—chief among them are safety risks and performance limitations.

In contrast, solid-state batteries replace the liquid electrolyte with a solid or quasi-solid material. The primary benefit? They are far less prone to the issues that plague conventional lithium-ion batteries, like electrolyte leakage or the dreaded thermal runaway (where the battery overheats, leading to potential fires). Additionally, solid-state batteries promise increased energy density, faster charging times, and lighter weight, making them a sort of "holy grail" in the EV world.

Enter FEST: Factorial's Quasi-Solid State Technology

The solid-state batteries that Stellantis plans to introduce in the 2027 Dodge Charger Daytona EV are developed by Factorial, Inc. This company has been at the forefront of battery innovation since its beginnings at Cornell University. Factorial’s battery technology, called the Factorial Electrolyte System Technology (FEST), is not entirely solid-state but rather a quasi-solid solution. It moves away from the conventional aqueous (liquid-based) electrolyte while still maintaining some fluidity in its design.

Despite not being a fully solid-state battery, the FEST technology is a major leap forward. Stellantis has announced that the 2027 Charger Daytona will feature FEST batteries with an energy density of 177 Wh/pound, a significant improvement over today's best aqueous lithium-ion batteries.

The Benefits of FEST in the Charger Daytona EV

One of the most exciting aspects of the FEST battery technology is the promise of significantly higher energy density. For context, traditional lithium-ion batteries with Nickel Manganese Cobalt (NMC) chemistry offer about 70 to 100 Wh/pound, while Lithium Iron Phosphate (LFP) variants manage around 40 to 60 Wh/pound. By comparison, FEST batteries are estimated to deliver 177 Wh/pound, representing a substantial leap forward.

This higher energy density means that the Charger Daytona will likely have increased range, faster charging capabilities, and reduced overall weight. A lighter battery means the vehicle could perform better in terms of handling and acceleration while consuming less energy. For enthusiasts of the Charger’s legacy as a performance muscle car, these advancements bring the promise of maintaining its aggressive reputation in the EV era.

To put this into perspective, consider that a conventional lead-acid car battery weighs about 40 pounds and has a paltry energy density of 30 Wh/pound. In contrast, a FEST battery of the same weight could hold up to 7 kWh of energy. For a larger battery pack like the one in a Tesla Model S, which has a capacity of about 100 kWh, a FEST-equipped Charger would require far fewer pounds of batteries to achieve the same or even better performance.

The Drawbacks: A Slow Road to Reality

As promising as it sounds, not everything about Stellantis’ plan for solid-state technology is without concern. The company has set a target for the 2027 Dodge Charger Daytona to feature FEST batteries, but that timeline comes with several caveats.

Firstly, Stellantis has only committed to producing a small demonstrator fleet using this new battery technology. This means it will likely take several years before solid-state batteries become widely available across Stellantis' full EV lineup. Secondly, the information available on FEST’s performance and reliability is still relatively sparse, which makes it difficult to predict just how well this technology will perform in real-world conditions. Factorial has been tight-lipped about some of the specifics, particularly regarding the cathode material used in their battery packs.

There are also concerns about Stellantis' ability to meet its aggressive deadlines. With delays already affecting other Stellantis electric models, like the Jeep Wagoneer S, there’s skepticism about whether the 2026 debut timeline for the Charger Daytona will hold up.

The Future of EVs with Solid-State Batteries

If Stellantis and Factorial can deliver on the promises of their quasi-solid state battery technology, it could signal a major breakthrough in the EV market. The benefits of solid-state batteries extend beyond just range and performance—they are also safer and more sustainable, offering fewer risks of overheating or dangerous chemical reactions compared to current lithium-ion technology.

For the Dodge Charger Daytona, a model known for its muscle car heritage, the introduction of solid-state batteries could help bridge the gap between old-school performance and modern electric efficiency. The Charger has long been a symbol of American automotive power, and if Stellantis can successfully bring these innovations to market, the Charger Daytona EV could redefine what it means to be a high-performance vehicle in the electric age.

Stellantis' decision to implement solid-state battery technology in the 2027 Dodge Charger Daytona EV is a bold and potentially game-changing move for the future of electric vehicles. With higher energy density, faster charging, and improved safety, the FEST batteries developed by Factorial hold the potential to make the Charger Daytona a true electric muscle car icon. However, with production delays and limited information still casting a shadow over the project, it remains to be seen whether Stellantis can deliver on these promises in the timeline they've set.

One thing is certain, though: the EV revolution is only accelerating, and solid-state batteries could very well be at the forefront of that transformation. For now, we’ll have to wait and see if Stellantis and Factorial can turn the dream of a solid-state Charger Daytona into a reality.
