BMW To Test Long Range Battery Made By Michigan Based Startup In Its Electric SUV

BMW will test a long-range battery made by Michigan-based startup Our Next Energy in the car manufacturer’s iX electric SUV, the companies announced Tuesday. ONE’s Gemini battery will use two types of battery cells, including one featuring advanced chemistry that can store more energy and enable vehicle range of at least 600 miles between charges, the company said.

The prototype automobile is expected to be finished by the end of the fiscal year, ONE said. The Gemini battery looks to cut down on the use of traditional electric vehicle battery materials like cobalt, nickel, graphite and lithium, ONE founder and CEO Mujeeb Ijaz said. Ijaz said ONE is testing a range of different electrode chemistries in Gemini while also analyzing possible tradeoffs in cost, energy and sustainability.

ONE may offer a production version of the battery in three varying sizes and prices. This would include a low-end version costing the equivalent, or potentially lower, as nickel- and cobalt-based batteries, Ijaz said. A BMW iX Flow with color-shifting material is displayed during CES 2022 at the Las Vegas Convention Center in Las Vegas, Nevada, U.S. January 6, 2022.

The battery maker is talking to other companies about similar prototype testing of its Gemini battery. BMW’s corporate venture department in March led a $65 million funding round in the battery company. The round’s other investors included Coatue Management, Breakthrough Energy Ventures, Assembly Ventures, Flex and Volta Energy Technologies.

ONE said in December that an early prototype of the Gemini battery modified in a Tesla Model S offered more than 750 miles of range, significantly more than the best production electric vehicles on the market. The logo of German car manufacturer BMW is pictured on a BMW car prior to the earnings press conference in Munich, Germany, Wednesday, March 20, 2019.

After ONE was founded in 2020, the company has centered its attention on a long-range battery that uses safer and more sustainable materials while also putting more energy into a smaller, cheaper package. BMW executive Juergen Hildinger said in a statement that the automaker is looking for opportunities “to integrate ONE’s battery technologies into models of our future BEV (battery electric vehicle) product lineup.”

Carmakers grapple with conflicting goals in designing electric-car batteries. They want high energy density for long range, but they also want to reduce the costly metals that provide that capacity.

Michigan battery startup Our Next Energy (ONE) claims to have a better way to optimize across all these factors. Now, BMW will fit an early prototype of ONE’s Gemini “Dual-Chemistry” battery into a test version of its iX EV luxury SUV to see if the claims—a heady 600 miles of range, nearly double the stock iX xDrive50’s EPA range estimates—are borne out in a variety of real-world uses. The test iX will be on the road by the end of this year, both companies say.

BMW is the logical vehicle partner to test ONE’s technology, because its investment arm—BMW i Ventures—was one of several backers in a $25 million round of financing for the battery startup last October.

Traction + Long Range

The Dual-Chemistry label on ONE’s Gemini battery refers to the pairing of two different types of battery cells, each with a different purpose.

The “Traction” portion has cells that use a lithium iron-phosphate (LFP) cathode, known to have a lower energy density than chemistries based on cobalt, nickel, manganese, or aluminum. LFP batteries are rare in North America, but common in Chinese EVs. Their use of cheap and easily available iron in the cathode leads battery analysts to suggest LFP cells will surge in popularity as their energy density rises, even though it remains below that of advanced cobalt-nickel cells.

The “Long Range” portion of ONE’s Gemini battery, on the other hand, uses a higher energy-density chemistry based on a proprietary material rich in manganese, with only minimal cobalt and nickel. During the current R&D phase, ONE founder and CEO Mujeeb Ijaz told Car and Driver, the company is still experimenting with blends of the three metals to enhance performance. Unusually, it has only a bare copper current collector—rather than separate anode material—a design known in academic circles as “anode-free.”

The LFP “Traction” cells will provide close to 99 percent of the vehicle’s overall miles, Ijaz said, while the “Long Range” cells kick in for the 1 percent of usage that requires extreme power, reducing stress on and deterioration of the LFP cells.

ONE says it can thus provide a battery with energy density that’s claimed to be double that of those in today’s EVs, while focusing on “safer” and “sustainable” battery chemistries created via a “conflict-free supply chain” that includes appropriately sourced and inexpensive manganese.

Lab Tests, Meet Real World

Hundreds of battery chemistries show at least some promise in lab tests, but far fewer make it into production—or even extended testing. The Gemini-powered BMW iX prototype will hit the road by the end of this year. It will be used as a demonstrator first, to prove the Gemini battery concept can store and deliver energy.

After that, BMW and ONE will work together on further testing. As Ijaz notes, ONE needs to “work with BMW to understand their requirements” for his company to become a long-term supplier. That’s an arduous path, but one every battery startup needs to travel before its products find a market.

The ONE-powered BMW iX will mark a new milestone for the company: Powering an actual vehicle, rather than simply showing bench-test results. The actual cells that will go into this early prototype pack will be fabricated by one or more of four separate supplier partners, both in Asia and North America, that are working with ONE on prototyping and production scale-up of its new cells.

When the iX is shown to run, charge, and cover the promised distances, ONE will have moved a large step away from its press stunt last December. In that effort, which ONE called a proof of concept, it stuffed cells with twice the energy capacity as a standard Tesla Model S into that car’s pack and ran it for more than 750 miles—or twice the usual range.

But those weren’t Gemini cells, whereas the BMW iX coming by the end of the year is expected to use very early and experimental versions of ONE’s new cells. This will count as definite progress, presuming it happens on schedule. Stay tuned.
