The American Our Next Energy (ONE) presented a completely anode-less batterywhich they claim is extremely high, practically its energy density is a record.
Supposedly it is half the price of the batteries used today.
Promising, special, problematic
A ONE batteries fundamentally questions what we thought we knew about batteriesbecause at all there is no anode in itcontains only cathode.
The special battery It uses LiMnO chemistry and is scheduled for mass production in 2026. That’s a good sign in one year, they were able to develop a 240 Ah prismatic cell operating from a 2 Ah bag cell, and traditional battery production equipment is said to be suitable for production. Due to the anode-less design, reduced graphite and other materials, and manufacturing processes, ONE predicts that when mass production comes, the price of the cell per kWh may drop to as low as $50.
In addition to the special structure and cheapness, the battery has another remarkable feature, namely its volumetric energy density of 1007 Wh/l. In comparison, for the better-known NMC cells used today, this value is roughly 670-740 Wh/l.
And then we arrived for the small print partwhich by the way is not so fine print, since the manufacturer is so aware of the drawbacks of the technology that you don’t even want to put the cell in a battery pack.
The anode-free design in itself is not an unknown solution, but such batteries have it many disadvantages, which is why they did not spread. Although their energy density is high, their production costs are low, and they do not really age simply with the progress of time – without use – but their more traditional counterparts only they are able to deliver more modest power, have a low number of cycles and are not as safe like say LFP.
In Hungarian, if only such a cell is installed in a car, it will not have a very long service life.
Therefore, LiMnO cells are a ONE designs it in a battery pack called Geminiwhere these only make up a part of the battery pack, they are supplemented by the more traditional ones LFP their variant siblings.
Normal in daily use, the car uses the LFP cellsand in the case of high-performance accelerations, it mainly loads them, but there are also cells without anodes for energy storage, which allow a longer range. Thus, the strain on these more delicate cells is reduced by 90%.
According to ONE, the LFP cells enable the first 240 kilometers of the journey, but with their anode-less counterparts The total range of the car can increase to 720 kilometers. The lifespan of the hybrid battery pack is predicted to be 400,000 kilometers, reports InsideEVs.
