Michigan-based startup Our Subsequent Power (ONE) this week unveiled a prismatic anode-free battery cell it claims will lay the inspiration for 600-mile EVs.
The prototype cell might be built-in right into a BMW iX prototype later this 12 months as a part of a dual-chemistry battery pack. ONE mentioned 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 can allow 600 miles of vary “in a variety of car 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 should pair the anode-free chemistry with lithium-iron phosphate (LFP) much like the type popularized by Chinese language automakers, and now utilized by Tesla in sure automobiles.

The 1007-wh/l anode-free cells remove 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. However 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.
Every chemistry is used for a selected operate—LFP for every day driving, and anode-free for long-distance journeys. With this association, ONE anticipates a 250,000-mile service life.

LFP cells enable constant charging and decreased demand for difficult-to-source components, however they are a bit heavier and want a lift in chilly climate—probably all remedied with this dual-chemistry strategy.
ONE seems to be the one entity attempting to take dual-chemistry battery packs mainstream, though it is definitely not the one firm fascinated with it. For example, Nissan has been working by itself solid-state cells, and inside that challenge it hasn’t dominated out combining chemistries inside packs.
Drivers of long-range electrical automobiles have a tendency hardly ever to faucet into the total vary and battery capability of their EV. So whereas many startups are betting on faster-charging cells, this strategy would possibly show not solely higher for automakers however the finish person as effectively.
