Firstly, this is still very much at the theoretical and experimental stage; they are still experimenting with different materials and aren't even remotely close to any kind of commercial product.
For metal-air batteries, of course there have been commercial applications for ages (zinc-air for instance), but specifically for Al-air batteries, that's right, and I never said otherwise. Just said it was certainly an interesting topic to keep an eye on.
Secondly, there is no mention of practical engineering issues like mass/volume increase when adding oxygen to aluminium in the kind of quantities that would make a practical vehicle electrical storage cell.
Maybe not in the very limited stuff I linked to, but this was not meant as a complete SoA. I clearly said it was just a start and that you could further look up many other references on the subject. Sorry about that, but I don't think Thunderf00t has made anything close to a decent SoA either here.
But I have definitely seen this kind of issues discussed in other papers.
Thirdly, there's no mention of any kind of recharging method, let alone one that would be safe and practical in the implied applications; indeed the only mention of even a rechargeable version of this technology is using highly exotic materials which are difficult to produce. Most of the technologies mentioned appear to be for primary cells, which are ridiculously inefficient compared to rechargeable ones.
There isn't, and this is exactly what I said earlier. The whole idea behind potentially using Al-air batteries from everything I've seen, is to indeed use them as "refillable" primary batteries. You'd basically get to a station equivalent to a gas station and replace the anode(s). The used ones would get recycled. Whether this would be inefficient on a large scale depends on many factors, but it's not as ridiculous as it may look if we can find efficient ways of recycling the anodes. Compare the cost of producing electricity, distributing it, the efficiency of chargers, the cost of extracting Lithium and Cobalt, the cost of producing Li-ion batteries, the cost of recycling them when they are dead, etc. What's going to be more expensive in the end? It's not necessarily as clear cut as it seems.
As I said, I think that should be seen as something similar to fuel cells, with similar benefits and constraints.
OTOH, any organization/company claiming electrically rechargeable Al-air batteries would just be a scam indeed, and any that would claim anything close to being ready to get to the market, even more so. That we can fully agree on.
Lastly, the whole article opens with a patently disingenuous statement that the energy density of Al - air is far superior to Li -ion, while the table further down the page clearly shows that comparable (ie Li - air) Li technology would have an energy density more than 50% greater than Al - air.
So? Are you sure you got the idea? Yes the energy density is far superior to Li-ion, which is currently the SoA kind of batteries used in EVs. Other metal-air batteries may pack even more energy density than Al-air, but have you considered the point? Al is one of the most common metals on Earth, far more pervasive and cheaper than Lithium. Li-air batteries would definitely be completely unpractical here, because again the whole idea is to be able to replace the anodes and easily recycle them. So the above comment missed the point completely IMO.
That it's currently not ready for commercial applications is obvious, that it may never see the light is probable too. But that it's a completely stupid approach not even worth considering, I don't quite agree here, and that was my point. And as I said in the previous post, if on top of that it conveys the idea that metal-air batteries don't even work, that's completely silly, and that would be where I think some Thunderf00t's videos, even though he does a good job overall, are overly clickbaity and misleading for the less informed viewers.
I again never claimed it was anywhere near ready for any commercial application. Would it even be worth funding a startup for this at this point? Not at all, would be ridiculous indeed. But is funding (reasonably) some research on metal-air batteries in general worth it? I think so.
And as I said earlier, the title "The battery that just won't die", is completely silly.
