Slate's upcoming electric pickup will launch with a 65-kWh lithium iron phosphate (LFP) battery instead of the nickel-based battery originally planned. The change helps lower manufacturing costs, increases driving range to 205 miles, and supports the company's goal of delivering one of the most affordable electric vehicles in the United States.
A Battery Strategy Focused on Affordability
As Slate prepares to begin deliveries of its first electric pickup later this year, the startup has made a significant change to one of the vehicle's most important components. Rather than using a nickel manganese cobalt (NMC) battery as initially proposed, the company has adopted an LFP battery supplied by Gotion.
The move aligns with Slate's broader mission of keeping vehicle prices low. With a starting price of $24,950, the truck is positioned to become both the least expensive new EV and the most affordable new pickup available in the U.S. market.
The battery packs will be produced at Gotion's facility in Illinois, while vehicle assembly will take place in Indiana, creating a relatively short supply chain that could help reduce transportation expenses.
Why LFP Batteries Became the Better Option
Several factors influenced Slate's decision.
When the company began developing the truck, federal EV incentives placed strict requirements on battery sourcing. Automakers seeking to qualify for the $7,500 federal tax credit had to ensure battery materials and components met domestic-content rules and avoided certain foreign supply chain connections.
At the time, meeting those requirements with LFP technology was difficult. Much of the global LFP battery industry was concentrated in China, and North American production capacity remained limited. As a result, Slate originally selected an NMC battery sourced from South Korea's SK On.
However, changes in federal policy altered the equation. With the tax-credit landscape shifting and domestic LFP manufacturing becoming more accessible, the company gained greater flexibility to reevaluate its battery strategy.
At the same time, LFP technology continued to mature. Production capacity expanded, costs declined, and battery performance improved enough to make it a practical solution for a value-focused vehicle.
How the New Battery Improved Range
One of the more notable outcomes of the switch is that the production truck now offers a longer estimated driving range than originally expected.
The finalized 65-kWh battery pack allows the vehicle to reach approximately 205 miles on a full charge. Earlier estimates for the truck were closer to 150 miles, meaning the production version significantly exceeds initial projections.
Part of this improvement comes from the battery's design. Slate uses prismatic cells and a module-free architecture that places cells directly inside the battery pack rather than grouping them into separate modules first.
This approach helps maximize available space within the vehicle's compact platform and improves overall energy packaging efficiency. Many established automakers are pursuing similar cell-to-pack strategies in their newest EV programs.
The proximity between battery manufacturing and vehicle assembly also contributes to lower logistical costs, supporting the company's affordability goals.
Trade-Offs of the LFP Approach
The transition to LFP is not without compromises.
Compared with NMC batteries, LFP cells typically provide lower energy density. They often require more physical space to store the same amount of energy and may deliver lower performance in some applications.
In Slate's case, peak output declined from 201 horsepower to 181 horsepower following the battery change. Despite the reduction, the company says acceleration performance remains effectively unchanged, with the truck still reaching 60 mph in roughly eight seconds.
For many buyers, especially those prioritizing cost and practicality, the trade-off may be acceptable.
LFP chemistry also offers advantages that are particularly useful in a lower-range vehicle. Owners can routinely charge the battery to 100% and discharge it more deeply without causing the same level of long-term degradation concerns often associated with nickel-rich battery chemistries.
A Single Battery for Launch
Earlier development plans included a higher-range version expected to travel around 240 miles per charge. That option is no longer part of the launch strategy.
According to company leadership, the new LFP pack already occupies the available battery space beneath the vehicle. Achieving substantially greater range would likely require a different chemistry with higher energy density.
Instead of offering multiple battery choices, Slate has decided to introduce the truck with a single configuration and evaluate market demand after production begins.
The company appears confident that 205 miles of range will satisfy many drivers, particularly those using the truck for commuting, local transportation, or commercial fleet operations.
Market Acceptance Remains the Key Question
The battery transition reflects a broader industry trend toward balancing cost and practicality rather than pursuing maximum range at any expense.
By combining a relatively simple vehicle design, domestic production, and lower-cost battery technology, Slate is attempting to reach buyers who may have been priced out of the current EV market.
Whether consumers embrace that formula remains uncertain. Interest appears strong, and reservations have already opened. The next major test will come when production starts in the fourth quarter of this year and customers decide whether affordability outweighs the compromises associated with a smaller battery and fewer premium features.
FAQ
Why did Slate replace its original battery plan?
Slate switched from an NMC battery to an LFP battery primarily to reduce costs and improve overall value. The company also gained more flexibility after changes to federal EV incentive rules.
What battery does the Slate truck use now?
The production vehicle uses a 65-kWh LFP battery pack supplied by Gotion and manufactured in Illinois.
How much range will the Slate EV truck offer?
Slate estimates the truck can travel approximately 205 miles on a full charge, an increase from earlier projections of around 150 miles.
Does the LFP battery affect performance?
Yes. Output decreased from 201 horsepower to 181 horsepower. However, the company says acceleration remains about eight seconds from 0 to 60 mph.
Why are LFP batteries becoming more popular?
LFP batteries are generally less expensive, more durable, and can be charged to full capacity more frequently. These characteristics make them attractive for affordable EVs.
Will Slate offer a larger battery later?
The company has not announced a larger battery version. Executives indicated that achieving significantly higher range would likely require a different battery chemistry.
