This may have been reported before, but it looks promising. Key is that the theoretical chemistry may have an unlimited number of charge-discharge cycles.
The original Edison batteries effectively never wore out (if the chemicals degraded because the battery was not maintained, they could flush and refil with fresh electrolyte and they worked fine). This newer version with nano-stuff seems to suffer some degradation over time, but perhaps they will find a way to fix it.
"Efficient" compared to what? If the electricity you use comes from a plant that is 3 times as efficient as burning the same fuel in your vehicle for propulsion, then a battery 50% efficient is better than fueling up with gasoline.
I'm hoping these batteries do well. I've always liked the technology behind them. They are about the only "forever" battery. They were good enough for the Germans to use them to power their V2 bombs in WW2.
Obviously, I was comparing their efficiency to other type batteries. The lower efficiency won't be a major concern for most EV applications but should be considered. It was a major concern for an off-grid application I was once working on. Even 80% efficiency for NiFe is a long way from the almost 100% charge/discharge efficiency of LiFePo4.

I agree. The big thing to me is the improvement in surface area. I believe these batteries have the potential for much higher energy density if not using large thick flat plates, but they will probably never be ideal for EVs.
The supplier I got my lithium battery from did show a nickel iron flooded prysmatic type (among a wide variety of other battery chemistries). Weight and efficiency concerns kept me from enquiring about them. I thought it was interesting to see a modern source was available.
