In collaboration with Our Next Energy (ONE), BMW has pushed the capabilities of its iX. The German electric SUV traveled 980 km on a single charge.
A BMW iX powered by ONE batteries covers 980 km
Headquartered in Michigan, USA, the company Our Next Energy has succeeded in increasing the range of the BMW iX. The German electric model, announced with a combined cycle range of up to 630 km (WLTP standard), traveled 980 km on a single charge. The capacity of the battery is however consistent, since ONE announces 185 kWh on its site!
The most interesting concerns the technology. This iX was equipped with the Gemini system. This is a dual chemistry battery. The first pack is made of lithium iron phosphate (LFP) cells and only activates for short trips. The second, of which we do not know the exact composition, is free of anode and uses “ a high proportion of manganese, which reduces the percentage of nickel and graphite “. This is activated over long distances, once the LFP part is discharged. The interest is that the two chemistries are associated together, which limits the place in relation to the capacity.

Our Next Energy believes its dual chemistry battery pack is the most promising on the market. The one that manages to combine great autonomy and small size. This battery uses 20% less graphite and 60% less nickel and cobalt than traditional lithium-ion cells. So it’s a battery. more sustainable » than those which are marketed today and obviously more efficient.
Soon a tenfold increase in autonomy for electric cars?
Mujeeb Ijaz, CEO and Founder of ONE, states that “ electric vehicles will be mass adopted when they offer enough range for users to consider them their primary car “. He recognizes that we are not there yet, but that the Gemini battery implemented in the BMW iX “ proves that it is possible to double the autonomy of an electric model “. Enough to eliminate the biggest obstacle to the adoption of electric vehicles.

The performance of the BMW iX with this new battery obviously gives ideas to the German manufacturer. Jürgen Hildinger, head of high-voltage technologies at BMW, says that “ we enjoyed working with the ONE team on this project. We now look forward to taking the next steps together “. Progress still needs to be made to improve the efficiency of the converter that helps unite the two cell chemistries.
I believe this technology can make a difference. We must remain cautious but I welcome this initiative which consists of working with materials “ more durable “. Our planet is lacking nickel. Same thing for cobalt. Interest in manganese is relevant for two reasons: the abundance of the metal (fifth most abundant metal in the earth’s crust) and its ability to reduce the cost of batteries. This dual chemistry technology is still in its infancy, but I believe it is very promising. The Chinese Gotion is a leader on the subject with its LMFP (lithium-iron-manganese-phosphate) battery which promises a range of 1,000 km on a single charge.
