Michigan-based startup Our Next Energy (ONE) this week unveiled a prismatic anode-free battery cell it claims will lay the inspiration for 600-mile EVs.
The prototype cell can be built-in right into a BMW iX prototype later this 12 months as a part of a dual-chemistry battery pack. ONE stated in a press launch that it is aiming for a volume-produced model of the dual-chemistry setup, referred to as Gemini, in 2026 that may allow 600 miles of vary “in a wide range of vehicle platforms” together with vans and SUVs.
ONE revealed its 600-mile check iX earlier this 12 months however hadn’t but detailed the chemistries. The startup now says it’s going to pair the anode-free chemistry with lithium iron phosphate (LFP) much like the sort popularized by Chinese automakers, and now utilized by Tesla in sure autos.

The 1007 Wh/L anode-free cells eradicate the necessity for graphite and manufacturing gear related to anodes, enabling cell prices of $50 per kwh at scale, or about half the price of present lithium-ion cells, ONE claims.
Anode-free cells sometimes have a decrease life cycle than typical lithium-ion cells, which might usually make them unsuitable for automotive use. But ONE claims its Gemini dual-chemistry packs remedy that downside with a 90% discount in cycle and peak energy necessities, including {that a} proprietary DC-DC converter permits the anode-free and LFP chemistries to be built-in into one pack.
Each chemistry is used for a particular perform—LFP for each day driving, and anode-free for long-distance journeys. With this association, ONE anticipates a 250,000-mile service life.

LFP cells permit constant charging and diminished demand for difficult-to-source elements, however they seem to be a bit heavier and want a lift in chilly climate—doubtless all remedied with this dual-chemistry method.
ONE seems to be the one entity attempting to take dual-chemistry battery packs mainstream, though it is actually not the one firm interested by it. For occasion, Nissan has been working by itself solid-state cells, and inside that undertaking it hasn’t dominated out combining chemistries inside packs.
Drivers of long-range electrical autos have a tendency not often to faucet into the complete vary and battery capability of their EV. So whereas many startups are betting on faster-charging cells, this method would possibly show not solely higher for automakers however the finish consumer as effectively.
