My friend was able to get me a copy of the Nature article.

That's why fast chargers are DC like Chademo. I thought about building one with
batteries. Slow charge them while you are asleep or at work and then fast dump
them in the car when you need it. Lot of expense for something I only need once

I'm not discounting the importance of charge time. It's just my understanding
that the batteries today aren't the limiting factor in charging. Actually

The only person I can imagine who might think that a one-minute discharge is
a big deal is a drag racer. The rest of us generally want to drive o

David,
Typical aluminum-air cells have a power density of around 60-70 W/kg, so
40 W/kg didn't seem out of line. To the contrary, it's the 3000 W/kg number
that seems awfully high.

You can't compare Watts/kg with Watt-hours/kg. That's like comparing
horsepower to gallons.

It sure looks interesting, more information here:
http://www.nature.com/nature/journal/vaop/ncurrent/full/nature14340.html
If I did the math correctly it seems like it's in the 120-140 wh/kg range.
Certainly usable for EVs.
Hopefully it makes it out of the lab.
